127 Mitacs Globalink (GRI) research projects for Summer 2027.
1. 48-hour fasting as a lever for metabolic health: is it effective and feasible across all ages? / Le jeûne de 48 h comme levier de santé métabolique: est-il efficace et applicable à tous les âges?
Intermittent fasting is gaining popularity both in the general community and in clinical settings due to its potential benefits, including weight management, improved vascular health, glycemic control, and immune function. However, few studies have specifically investigated its effects in older adults, limiting our understanding of both clinical benefits and feasibility in this population.
This project aims to evaluate the feasibility and acceptability of a 48-hour fasting protocol in healthy young adults and older adults. We will recruit 15 young adults (20–35 years) and 15 older adults (55–70 years) to complete a 48-hour fast (no caloric intake). Assessments will be conducted before, during, and after the fast. The primary objectives are to measure adherence, tolerance, and any adverse effects associated with the fast. Secondary objectives include examining metabolic responses (e.g., continuous glucose monitoring), vascular health (e.g., endothelial function and stress responses assessed in the lab), immune function (assessed via ex vivo cellular assays), subjective perceptions (e.g., fatigue, hunger, mood), and compensatory behaviors, monitored via accelerometry to assess changes in physical activity during and after fasting.
This project integrates a wide range of clinical measurements – such as blood pressure, capillary glucose, and continuous glucose monitoring – with mechanistic assessments, including cellular assays and vascular function testing. This multidisciplinary approach provides the intern with hands-on experience across diverse research techniques and equipment. In addition, related projects, including meta-analyses and large-scale epidemiological studies, offer the intern opportunities to engage in complementary analyses depending on their interests.
Research area, student roles & skills
Research area: My research focuses on human physiology and metabolic health, with a particular emphasis on nutritional interventions such as fasting and ketogenic approaches, as well as exercise strategies (e.g., high-intensity interval training, exercise snacks). My work aims to better understand the metabolic, inflammatory, and vascular mechanisms underlying short- and long-term adaptations to these interventions. I employ a translational research approach that integrates epidemiological studies, randomized controlled trials, and ex vivo experiments to evaluate their impact on the prevention and management of cardiometabolic diseases.
Student roles: During this internship, the student will receive personalized guidance tailored to their skills and objectives. Roles and responsibilities may vary depending on the student’s interests. The internship takes place at the Research Center on Aging, a large-scale research institute bringing together a diverse group of researchers and students, providing a stimulating and multidisciplinary research environment. For the proposed project, the student will be actively involved in all stages of implementation, including participant recruitment, collection of physiological data and questionnaires, and data management and organization. This will include, among other tasks, measuring blood pressure, capillary glucose monitoring, and laboratory experiments on cells, including whole blood cultures and immune cell stimulation. The student will also contribute to preliminary data analyses and the interpretation of results in relation to defined research sub-questions. They will participate in team meetings and may propose additional analyses or ideas based on their interests. Additionally, the student will have the opportunity to engage in related ongoing projects at the center, such as studies using large epidemiological datasets (e.g., NHANES) or meta-analysis projects. This exposure to diverse research activities will allow the student to develop a wide range of skills, from clinical data collection to statistical analysis and scientific synthesis.
Skills required: We are looking for a motivated and curious student eager to gain practical research experience! A background in kinesiology, physiology, nutrition, biomedical sciences, or a related field is preferred, but not mandatory Prior research experience, including data collection or participation in projects/stages, is an asset. Skills in data analysis and/or scientific writing (French or English) are valued. The student should be organized, methodical, able to work independently while collaborating effectively within an interdisciplinary team, and comfortable interacting with human participants.
2. Bio-conjugate therapeutics for Alzheimer's disease.
The objective of this project is to develop a therapeutic bio-conjugate that will reduce the amount of glutamate in the brain to a `normal' level, over a period of 1 -3 weeks after a single administration. Re-administration of the bio-conjugate at regular intervals will contribute to maintaining `normal' levels of brain glutamate, which could stop or slow the progression of AD.
Research area, student roles & skills
Research area: Alzheimer's disease (AD) is the most common age-dependent neurodegenerative disorder, and afflicts more than 44 million individuals worldwide. One of the hallmarks of AD is the presence of excess glutamate in the brain. Glutamate, a neurotransmitter, is the most abundant free amino acid in the central nervous system. Unfortunately, when present in excessive amounts, glutamate becomes toxic and, via a complex set of processes, leads to cognitive impairment. The latter can involve problems with memory, language, thinking, and judgment, which are greater than normal age-related changes.
Student roles: Read associated literature, conduct experiments (under supervision of senior lab member), interpret results, write a final internship report (10 pages), and make a final oral presentation to lab members (10 min).
Skills required: All associated techniques will be taught on-site. Background in chemistry, biochemistry, or biology are seen as most appropriate for capitalizing upon this learning experience.
3. Biochemical Analysis of Saskatchewan (Canada) Prairie Medicinal Plants
Our first objective is to perform a survey of approximately 10 native plant species growing in Southern Saskatchewan: After identifying organic compounds within each species to provide a chemical “fingerprint” for general identification, we will compare abundant molecules to known privileged structures. We intend to characterize the plants through their chemical bioactive components. Traditional Indigenous medicine is holistic in nature and characterizing their chemical bioactive compounds is inclusive of these active components in the plant. Crude metabolites of the species selected will be obtained using Soxhlet and orbital shaker extraction with methanol at low temperature using environmentally benign techniques where green solvents are used or relatively non-toxic solvents are recycled for repeated use. Filtration, preparative column chromatography, and recrystallization will then be implemented to prepare both crude and pure extracts for biochemical analysis.
Another objective is to perform a thorough investigation of medicinally interesting components and their associated structure for secondary metabolites that are present in abundant quantity. This will allow us to use selected plants in our survey as sources for complex molecules which would otherwise be prohibitively expensive to synthesize through traditional organic chemistry methodology. The plant metabolite-analysis stage will provide insight into the most chemically diverse and promising species.
Research area, student roles & skills
Research area: In light of the decrease in the native prairie plants, our research objective is to study Saskatchewan native prairie plants and how their bioactive components relate to their traditional and medicinal uses. Our research objectives are 1) to perform a biochemical survey of metabolites of native plant species growing in Saskatchewan and 2) to investigate medicinally interesting secondary metabolites and compare them to other privileged structures useful in drug discovery. This research will help to preserve these indigenous plants through better appreciation of their bioactive compounds, their traditional uses and future potential.
Student roles: The student will help us in the lab during these analyses: - Soxhlet extraction - Silica gel column chromatography - Biochemical assays - Literature analysis The student will participate in plant harvesting with Elders. The student will write a report at the end of the internship.
Skills required: The student should have the following skills/background: - An interest to learn about chemistry, biocheemistry and plant biology. - An interest to learn about Indigenous knowledge and culture. - Chemistry experience/knowledge with these methods/instruments: - Soxhlet extraction - Silica gel column chromatography - Plant harvest on the land - Processing harvested plants - Working with Indigenous Elders and Traditional Knowledge keepers in the field and on campus
4. Biochemical characterization of novel carbohydrate active enzymes

The student may use multi-step chemical synthesis to prepare a new substrate or inhibitor, or the student may develop an assay and measure the Michaelis-Menten parameters for a specific enzyme. Assays may involve UV, HPLC, TLC or NMR analysis. The research project will be written up by the student in English with a view to publishing novel research results.
Research area, student roles & skills
Research area: The research laboratory focuses on understanding the chemistry and biochemistry of enzymes involved in metabolizing carbohydrates in bacteria. Studying these enzymes will result in new insight into the mechanism of action, the structure and the function of these catalysts. These enzymes are potentially drug targets. Potent inhibition is a potential avenue towards developing new antibiotics. The laboratory uses a wide variety of chemical techniques, organic synthesis, carbohydrate chemistry, enzymology, HPLC, TLC, NMR, gene cloning and protein engineering. Students will be exposed to some or all of these techniques.
Student roles: The student will conduct all of the experiments, with assistance from a graduate student or post-doctoral fellow present in the laboratory to assist with day-to-day queries. The student will write up their research findings daily in their laboratory notebook. This will be reviewed by the supervisor and more senior researchers on a daily basis. The student will be required to present their research findings daily to their supervisor in English. They will be required to prepare weekly powerpoint presentations outlining their productivity and present to the research group (up to 10 graduate students and post-doctoral fellows). They will be required to write an end of experience report in English.
Skills required: Students need to have strong quantitative lab skills, understand the principles and practical aspects of organic synthesis, be familiar with TLC and HPLC, UV visible spectroscopy and 1D and 2D NMR spectroscopy. Understanding the theory of these techniques is a requirement. Potential students need to demonstrate in their application how their current experiences demonstrate this knowledge. Hands-on training for the techniques will, however, be provided.
5. Biophysical Characterization of Alpha-Synuclein Phase Separation
This project will leverage advanced biophysical and light microscopy approaches to dissect how α-syn structure influences phase separation and synaptic function. The successful applicant will:
• Utilize non-canonical fluorescent amino acids incorporated via genetic code expansion to generate α-syn variants optimized for FRET and FLIM-based structural monitoring.
• Combine recombinant protein assays with live-cell imaging to visualize α-syn condensate formation and conformational shifts in real time.
• Apply circular dichroism (CD), dynamic light scattering (DLS), and protein biochemistry to quantify structural rearrangements during LLPS.
• Assess how α-syn LLPS impacts SNARE complex assembly, vesicle clustering, recycling, and presynaptic organization.
Research area, student roles & skills
Research area: α-Synuclein (α-syn) is a presynaptic protein with diverse structural conformations. In solution, it is intrinsically disordered, while membrane-bound, it adopts a predominantly α-helical form. The intrinsically disordered regions of α-syn also render it capable of undergoing LLPS. LLPS has been implicated in the assembly of both the presynaptic active zone and the postsynaptic density, where it influences the release and reception of neurotransmitters. We therefore seek to define the role of α-syn-mediated LLPS in vesicle release and recycling at the presynaptic active zone.

Students interested in pursuing graduate studies and contributing to collaborative research projects are particularly encouraged to apply.
7. Cell-Matrix adhesion in tissue development & homeostasis 2026
Supervisor: Guy Tanentzapf
University: University of British Columbia (Vancouver campus)
Cell adhesion regulation plays a key role in animal development and tissue maintenance: Adhesion proteins of the integrin family are the core components of an adhesion complex that is important for attaching cells to the extracellular matrix (ECM). Integrins are involved in many biological processes including cell migration, organogenesis, and the maintenance of tissue integrity under conditions of mechanical stress. Our lab looks at how the regulation of the assembly, strength, and turnover of integrin adhesions contributes to animal development and tissue maintenance. My lab uses genome-engineering techniques to create animal models containing mutations that disrupt key regulatory mechanisms that control integrin-mediated Cell-ECM adhesion. We then analyse these mutants in diverse biological contexts. The MITACS funded project will involve analysing such animal models using advanced quantitative imaging, live imaging of primary cell culture and cultured whole embryos and explants. Moreover, histology and immunohistochemistry will be used to analyse functional defects that arise during embryonic development that effect the regulation of cell migration and stable cell adhesion. The work will be carried out in either the genetic model organism Drosophila Melanogaster or in mouse models. Working under the supervision of a senior member of the lab the student will learn cutting edge techniques of imaging to analyse the cell morphology, cell migration, and localization of intracellular components in different compartments within cells of interest. The work carried out by the student will provide novel insight into the physiological roles of different regulatory mechanisms that operate on integrin-based adhesions.
Research area, student roles & skills
Research area: The Tanentzapf Lab is located in an interactive, multi-lab setting in the new Life Sciences Institute at the University of British Columbia in beautiful Vancouver, Canada. Our lab studies a fundamental question of how cells in our bodies connect to the Extracellular Matrix (ECM), which is the material that makes up connective tissue. We use advanced imaging, genetic, and molecular tools to construct and analyse genetic models to study the regulation go how cells attach to the ECM. Cell-ECM adhesion has diverse and important roles during the development and life of an organism and determines its morphology and physiology.
Student roles: The student would set up and design genetic crosses and/or carry out cell culture work. The student will perform live imaging on mouse explants or whole flies of specific genotypes, the student will carry out immunohistochemistry and histological experiments on fixed tissue as well as make high resolution movies of in vivo developmental processes. The student will analyze the resulting images and movies using image analysis software. The student will be actively involved in developing methodologies of image gathering and analysis. Student will gain critical thinking and experimental design skills by working closely with other lab personnel.
Skills required: We are seeking an eager, hard-working student interested in the fields of developmental and cell biology, and advanced imaging technology. The project may involves genetics and/or cell culture techniques, a substantial amount a imaging work using a scanning laser confocal microscope and image analysis software. Familiarity with these techniques would be an advantage. Previous experience in a research lab and knowledge of developmental biology/genetics would be be an asset but not essential. The student must be comfortable with the application and use of math and physics to biological problems and we very much encourage applications from students with math/physics/engineering backgrounds.

10. Chromatin-based epigenetic mechanisms in gene expresssion and genome maintenance
Our work characterizes the structure and function of several protein complexes, identifying their intrinsic recognition modules for the epigenetic histone signature. Accurate writing and reading of these epigenetic marks lead to changes in chromatin dynamics, in a targeted manner within the genome. The project will aim to continue this work to understand the role and structure of multiprotein complexes modifying chromatin, controlling gene expression and maintaining the integrity of the genome in physiological or pathological context (see website). The model systems used are mammalian cells and the yeast Saccharomyces cerevisiae. The techniques used are at the cutting edge of molecular biology and genetics as well as protein biochemistry and functional genomics (protein purifications, mutagenesis, CRISPR/Cas9-genome editing, recombinant proteins, Next-generation sequencing, molecular interactions, immunoprecipitations , cellular imaging, etc.).
Research area, student roles & skills
Research area: Our research aim is to understand chromatin dynamics associated with gene regulation and DNA repair. We study protein complexes that control acetylation and methylation of histones, and the composition of chromatin. We dissect the molecular mechanisms of epigenetics, in which signals to chromatin mark different genomic loci and are read by effectors to translate a biological response.
Student roles: The student will be responsible for his own research project, with of course initial supervision. The project will be better defined in May 2027 according to the progress of the current research of the lab.
Skills required: A student with laboratory work experience is sought for an internship from May to August 2027. A background in molecular biology is an asset and a good academic record is required (A). An interest in research and graduate studies is also very advantageous. An ability to communicate in English is also an advantage or a learning opportunity given that the laboratory has five non-French speaking people. Lab meetings are in English.
11. Cloning of a gene coding for an interesting stress-responsive protein
The research project is in the field of bioengineering, which will prepare the students to work or pursue graduate studies in biotechnology, synthetic biology, or environmental biology. It is about cloning a plant gene in an Escherichia coli strain commonly used in the laboratory to produce recombinant protein for biochemical characterization. We have recently identified very interesting protein candidates that may provide stress tolerance to plants or be useful in biotechnology or synthetic biology. We hypothesize that the variant of these proteins might be ones that make the plants sensitive to some abiotic stress factors. This present project aims to test this hypothesis. For this, we want two Mitacs interns to join our dynamic and talented team of young researchers to help us clone and express the recombinant proteins of two of these genes.
Research area, student roles & skills
Research area: Our research mainly focuses on the plant's response to abiotic stresses, including drought, cold, heat, and high soil salinity. Enzymes such as aldehyde dehydrogenases are strongly involved in detoxifying free radicals generated in the plant due to environmental changes. This detoxification activity is very crucial to the growth and survival of the plant under these adverse environmental conditions. We seek to characterize the function of these enzymes and of other plant stress proteins to make plants more resilient to climate change. We also study the mechanisms of signalling by free radicals through the oxidation of proteins in higher plants.
Student roles: The project is about cloning two genes. Therefore, we want to host two students on this project, and each student will clone one gene. The students will use the Polymerization Chain Reaction (PCR) to obtain a fragment of the gene. Then, the gene fragment will be cloned into a plasmid vector by using restriction enzymes and a ligase. The success of the cloning will be verified by colony-PCR, plasmid DNA extraction, and DNA restriction analysis on an agarose gel. If time permits, the students will express and purify the recombinant proteins by using affinity chromatography on a gravity column or with FPLC. The internship aims to familiarize the students with gene cloning, a fundamental skill required in any laboratory of cellular and molecular biology. The project will enhance the students' practical skills in molecular biology and biochemistry.
Skills required: The students should have a background in molecular biology, biochemistry, or plant biology.
12. Combination Therapy Using saRNA and Oncolytic Viruses for Brain Cancer
Combining therapeutic platforms is a promising strategy to overcome the limitations of single-agent treatments in aggressive cancers like glioblastoma. This project aims to investigate the synergy between RNA-based immunotherapies and oncolytic virotherapy.
The student will explore how saRNA constructs encoding immune modulators can enhance the efficacy of engineered oncolytic viruses developed in Dr. Azad’s lab. The central hypothesis is that RNA-mediated immune activation can complement viral oncolysis, leading to improved tumor cell killing and stronger anti-tumor immune responses.
The project will involve co-treatment experiments in glioma cell lines, comparing single-agent and combination approaches. Key readouts will include viral replication, transgene expression, immune signaling pathways, and tumor cell viability. The student will also assess markers of apoptosis and cytokine production to understand the mechanisms underlying any observed synergy.
Depending on progress, the project may extend to more advanced models to further evaluate therapeutic potential. The student will gain experience working with both RNA therapeutics and viral platforms, offering a unique multidisciplinary perspective.
This project is particularly well suited for students interested in innovative cancer therapies and translational research. It bridges multiple cutting-edge approaches and has strong potential to contribute to next-generation combination treatment strategies.
Research area, student roles & skills

Strong problem-solving skills, the ability to learn new techniques quickly, and good organizational habits are important. Students should also be able to work both independently and as part of a collaborative team.
13. Compatibilization of bio-based polymers for the development of bioactive nanocomposite films in food applications
This project aims to study the physical and/or chemical compatibilization of bio-based polymers and biopolymers to develop stabilized encapsulation devices such as bioactive packaging films, edible coatings, gelled microcapsules/microemulsions. Two (2) aspects will be investigated: 1) improvement of the device component interactions (optimization of the effect of components: polymers, plasticizers, crosslinkers, nanoparticles, compatibilizers) on the mechanical and barrier properties of devices; 2) improvement of interactions between the polymeric device and encapsulated bioactive agents (natural extracts, nanoemulsions, metal nanoparticles) by different methods (encapsulation, reactive extrusion, functionalization, grafting, etc.).
Hypothesis: The compatibilization of polymer components optimizes interactions with bioactive agent/nanoparticles and significantly improves the functional properties of the resulting bioactive polymeric matrix.
Objectives:
1) Optimize methods of compatibilization: physical (sonication, microfluidization, irradiation, compression molding, extrusion) and chemical (functionalization, grafting, crosslinking, hydrophobization, reactive extrusion) with applications in bioactive packaging films, patches, edible coatings, microemulsions/microcapsules.
2) Characterize the physical/chemical reactions by structure, rheological and physicochemical analyses.
3) Determine the in vitro antioxidant capacity of the polymeric matrix.
4) Determine the in vitro and in situ antimicrobial properties of the polymeric matrix.
5) Evaluate the effect of compatibilization on the controlled release of bioactive agents during storage.
Methodology:
Compatibilization and polymeric carriers will be developed according to procedures from our laboratories. Bioactive agents will be selected based on our previous studies. The molecular structure of the supports will be analyzed by FTIR spectroscopy, SEM analysis, contact angle and UV spectrophotometry. The mechanical properties, gas barriers properties and water resistance of the polymer matrices will be also measured to verify the effect of functionalization. The antioxidant properties of the films will be determined according to various methods (DPPD, DPPH, TBARS). The release of bioactive agents during storage will be assessed on the best formulations based on in vitro methods performed in simulated food media.

Essential: The student can work under a chemical hood, a biological safety cabinet and have received WHMIS and Biosafety trainings.
14. Computational Modeling of Bacterial Membrane Systems
Supervisor: Katie Wilson
University: Memorial University of Newfoundland (St. John's campus)
The World Health Organization has identified multidrug-resistant bacteria as a critical global health threat. One promising strategy to combat antibiotic-resistant infections is targeting the bacterial membrane—a structure essential for bacterial survival and distinct from mammalian membranes.This project will use computer-based techniques, specifically molecular dynamics simulations, to visualize and analyze how antimicrobial agents, such as antimicrobial peptides, interact with bacterial membranes. Bacterial membranes are composed of a variety of lipid species, including phosphatidylethanolamine (PE), phosphatidylglycerol (PG), cardiolipin (CDL), and glycolipids. In contrast, mammalian membranes primarily contain neutral lipids (e.g., phosphatidylcholine, PC) and cholesterol. The student will simulate and compare the structural effects of antimicrobial agents on different membrane compositions to identify features of drug molecules that enable selective targeting of bacterial membranes without harming mammalian cells. This research will provide insight into the molecular basis of membrane selectivity—an important step toward the rational design of new therapeutics. Through this project, the student will gain hands-on experience in computational biochemistry and contribute to efforts addressing the global antibiotic resistance crisis by helping to inform the development of safer, more effective antimicrobial agents.
Research area, student roles & skills
Research area: Research in the group sits at the interface of biochemistry, chemistry, biophysics and computer science. Through using computer models we can observe atomic interactions to obtain high-resolution structural, dynamical and mechanistic information about biochemical processes. The group used a multiscale computational modeling approach with techniques including density functional theory, machine learning, hybrid (QM/MM) calculations, atomistic molecular dynamics simulations, and coarse grain molecular dynamics simulations. Research in the group revolves around deciphering the inner workings of complex biochemical systems related to human health and disease.
Student roles: Students in my group learn computer modeling techniques that are routinely used in academic and industry research. Through performing research in the group, students will learn skills in scientific communication, critical thinking, problem solving and teamwork. I make mentorship of students a priority and interact with students regularly to ensure their success. Students will start their project by completing tutorials and sample calculations that introduce them to the skills and techniques that are required for their projects. The training will provide the students with a broad understanding of the practical aspects of computational biochemistry and related computer science skills. Student will then be given a small research project that is linked to a larger research project in the group. Throughout the position the student will be involved in running calculations, data analysis, and presenting their results through written and/or oral communication.
Skills required: Research in my group is multidisciplinary and therefore students should have knowledge in topics related to biochemistry (e.g., bimolecular structure), chemistry (e.g., physical chemistry) and physics. Prior knowledge in coding or computational modeling is helpful for the project but is not required. Students will be expected to be able to work both independently and as part of the team. The Wilson lab is dedicated to creating an inclusive and equitable environment where all members of the team are supported, and are able to participate both within the lab and in social work settings.
15. Computationally understanding vibrational features of noble metal and single molecule interaction mechanism
Supervisor: Nisha Rani Agarwal
University: Ontario Tech University (Oshawa campus)
Metal-protein interactions in a biological system is responsible for transport and transfer of materials in the body. In this project, we would like to understand the hemoglobin interaction with noble metals for sensing purposes. The sensing is done by detecting the detecting the intrinsic vibrational features of the molecule. Achievement of high plasmonic enhancements for reaching higher sensitivity of analytes is since ever at the forefront of research activity in the field of Surface Enhanced Raman Scattering (SERS). Hence, there is
a strong drive to fabricate efficient nanostructured substrates for SERS. The composition, size and nanostructure of an artificially roughened surface can be changed over wide ranges, depending on the technique and the process parameters used in the fabrication. Nevertheless, some special sites known as hot spots contribute to the strongest signal enhancement that can be as high as 10^10, thus allowing for the detection of Raman signals from single molecules.
Research area, student roles & skills
Research area: My expertise lies in development of novel characterization techniques for bio-sensing and plasmonic applications. Mostly, these characterization techniques deal with spectroscopy and force microscopy. Currently, I am using these techniques to understand interaction between noble metals and heavy metal carrying molecules in biological systems. For instance, hemoglobin interacting with gold nanostructured surfaces.
Student roles: 1. Understand the software ORCA or other to perform smulations 2. Design the system for understanding chemical interaction of the systems. 3. Test the model system. 4. Analysis of data and conclusion of results All data from different measurements will have to be evaluated and analyzed. Results will be interpreted logically and discussed scientifically. 5. Documentation and presentation of research project: A report has to be written at the conclusion of the research project. This will be considered an official document for the student. Furthermore, the student will be encouraged to present their results to the scientific community as an oral presentation.
Skills required: The project is best suited for graduate and undergraduate students in physics, chemistry and materials engineering seeking to enhance computation,laboratory, analytical and interpersonal skills. The students should possess excellent scientific acumen and theoretical knowledge of physical chemistry. The student will work in highly collaborative environment. Thus, good communication abilities are desirable. The nature of research stretches across multiple disciplines and hence strong background in the following areas are required: -Basics of atomic, molecular and optical physics (undergraduate physics) -Basics of inorganic and functional chemistry (undergraduate chemistry) -Basics of materials science and spectroscopy (undergraduate materials engineering) -General mathematics and chemistry
16. Constraint-based modelling of secondary metabolism
Many of the chemical products we are interested in making, such as biopolymers, are secondary metabolites, which means that they are not essential to microbial growth. As a result, their production is subject to specific resource constraints that are typically not captured in constraint-based modelling, such as flux balance analysis (FBA). In particular, proteomic constraints play a big role in determining the yield of secondary metabolites. Yet, such constraints cannot be easily integrated into FBA and its derivatives; current formulations require deep proteomic characterization that is expensive and time-consuming to carry out. This makes predicting the performance of secondary pathways difficult. We are developing a coarse-grained approach that will make evaluating secondary pathway performance much easier and more generalized across organisms and specific pathways. This tool will significantly enhance the metabolic engineering toolkit, while also helping us to make fundamental advances in understanding microbial metabolism.
Research area, student roles & skills
Research area: At the Laboratory for Anabolic Bioengineering (the LAB), our broad aim is to find ways to make chemicals sustainably using engineered microbial catalysts. Our work spans theory/computational tool development all the way to scale-up of bioprocesses making use of our engineered microbes. We have core research interests in developing new computational tools to help us make bettern predictions about how to design productive strains, and to advance our fundamental understanding of microbial metabolism/physiology.
Student roles: The student will be mentored by a PhD student who is leading the project. They will spend a majority of their time doing dry lab, or in silico, work. This will include conceptualizing and running test cases, building digital infrastructure to support package development, and developing new models for various biological scenarios within the framework we have developed. There may be opportunities to participate in wet lab characterization, but this will depend on the progress of the project. The student will have multiple opportunities to communicate their research to the group and/or within the department.
Skills required: The student should have good mathematics and coding skills. Some familiarity with linear programming would be very helpful, but is not critical. Familiarity with coding in Python is essential. The ideal student would also have a good background in biological principles. Above all, enthusiasm for the project and its outcomes is most important.
17. Contact killing of COVID-19 by copper-based nanoparticles.
The primary goal of this proposal is to decipher the virucidal efficacy of carboxymethyl cellulose copper (CMC-Cu) nanoparticles against COVID-19 (formally named SARS-CoV-2). The studies will be performed in partnership with a Canadian company. Microbes are rapidly killed on surfaces of copper and copper alloys through a process named copper-mediated "contact killing". Furthermore, a recent study has revealed that COVID-19 is not viable upon exposure to copper surfaces. Of significance, copper concentrations required to kill microbes are not toxic for humans. Creating "self-disinfecting surfaces" by coating inanimate surfaces with copper is difficult to apply for practical and economic reasons. However, an exciting avenue is the recent discovery of CMC-Cu as an effective alternative to one-step disinfectant agent that significantly reduces microbial levels on surfaces and inanimate objects. Using an innovative method enabling production of MLV-based COVID-19 pseudotyped particles in a biosafety level 2 (BSL-2) laboratory, we will investigate COVID-19 unstability and its inability to attach and infect target cells in the presence of CMC-Cu in the absence of other reagent or in the presence of selected disinfectant products.
Research area, student roles & skills
Research area: Our goal is to take advantage of the unique biocide property of carboxymethyl cellulose copper (CMC-Cu) nanoparticles to eliminate COVID-19 present on surfaces and inanimate. The recently emerged novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2/COVID-19) poses a striking challenge for public facilities. Public spaces become rapidly contaminated by human-to-human transmission. Given that cellulosic copper nanoparticles have been shown to be uniquely toxic for microbes and safe for human tissue, we will investigate the toxicological effects of CMC-Cu treatments to COVID-19 using a method enabling generation of non-infectious MLV-based COVID-19 pseudotyped particles in a BSL-2 setting.
Student roles: The student will be involved in a research projet in which he/she will have to apply molecular and cellular approaches to perform biological experiments. The student will develop her/his own sub-project to gain independence and autonomy skills.
The students involved in the proposed research program will learn a broad spectrum of experimental approaches, including new proteomics strategies and several applications involving next generation sequencing for genome-wide analysis of gene expression changes. Although each student will primary work on a specific aim, collaboration between students will be highly encouraged to ensure that they gain mastery over all the laboratory methods.
Each week, we have a: Lab meeting: a member describes her/his results and experimental problems in order to exchange ideas and receive constructive criticism. Journal club: to discuss and comment publications relevant to our field or other areas.
Departmental group seminar: the graduate students are exposed to "tell a story" and exchange about their results with other graduate students and professors of the Department.
Skills required: Highly interested student who is eager to learn molecular and cellular biology as well as yeast genetics. New generation sequencing (NGS) approaches (e.g. RNA-Seq) will be used and a combination of bioinformatics tools will be available for the trainees.
18. Contribution of alternative splicing to fibroblast biology
Supervisor: Jean-Philippe Brosseau
University: Université de Sherbrooke
Location: Sherbrooke, Québec
Start date: 2027-05-31 (flexible)
Disciplines: Biochemistry, Biological Sciences, Biology, Molecular Biology, Genetics, Health Studies, Medical Sciences, Medicine
Alternative splicing is a powerful mechanism that expands the proteome diversity by allowing the transcription of multiple messenger RNAs from a single gene. Numerous examples have illustrated the functional impact of alternative splicing in the literature. There is also a high level of understanding of the major factors influencing a splicing decision (e.g. RNA sequence in cis and RNA binding factors acting in trans), recently culminating into a "splicing code". However, there is not much known about the upstream mechanisms controlling the expression/activity of splicing factors and even less linking extracellular factors to alternative splicing regulation. Our laboratory is interested in deciphering the regulatory mechanisms upstream of an alternative splicing network orchestrating key developmental programs in humans.
Research area, student roles & skills
Research area: Our laboratory has an interest and expertise in elucidating gene expression programs involved in tumorigenesis, especially those involving cells in the tumor microenvironment.

In addition, we are developing molecules (antisense oligonucleotides) to reduce tumor growth in pre-clinical models.
Student roles: The student will follow established standard protocols to perform molecular biology and biochemistry techniques such as human cell culture (passage, transfection, phenotypic assay); gene expression determination at the RNA (RNA extraction, cDNA synthesis, real-time PCR) and protein (protein extraction, western-blot) level. Expect to communicate results and participate in lab meetings
Skills required: Background in life sciences or medicine. Coachable. Self-motivated. Easily adapt to a new situation. A desire for a career in research Interest in RNA processing and alternative splicing Interest in learning cell culture, gene expression analysis
19. Coordination based assemblies for electrochromic (EC), electro-optic, and photonic materials. (1)
Supervisor: Olena Zenkina
University: Ontario Tech University (Oshawa campus)
Coordination based SAMs (self-assembled monolayers) will be prepared and examined as robust functional EC materials and in molecular electronics. We will prepare a series of nitrogenous ligand -Fe2+ type materials covalently anchored on an appropriate support (TiO2, WO2, FTO/on glass; or silicon). Subsequently, we will fine-tune the colour of our assemblies by rational ligand modification.Varying the number of pyridine moieties and changing the nature of the organic functionalities in one or several pyridine rings, (introducing a conjugated organic moiety or fused aromatic ring), or metal moiety will significantly affect metal to ligand (M-L) charge transfer and as a result change the colour of the metal complex. Through this approach, we will access different colours (red to blue). From preliminary results with terpyridine-Fe2+ SAM covalently immobilized on FTO/glass, electrochemical switching the oxidation state from Fe2+ to Fe3+ results in complete decolouration of the material. We will explore chemical and electrochemical switching properties, stability, conductivity and colour efficiency of these novel materials. The ultimate goal will be to create applicable EC materials with high coloration efficiency, colour homogeneity, high contrast ratios and controllable switching time. Changes in molecular design and deposition procedures (SA in solution and vacuum deposition) will be used to explore different arrangements on the surface. Structural factors such as length and bulkiness of the organic spacer, sterics and electronics, and the nature of the metal moiety, will be varied in order to investigate their influence on the packing density and properties of the SAMs. Finally, molecular wire-like highly conductive materials on activated silicon surface could be achieved using vinyl-terminated molecules.
Research area, student roles & skills
Research area: The Zenkina research group in Materials Chemistry focuses on the development of novel nanostructures employing self-assembly of organic and organometallic compounds on metal and oxide surfaces with a heavy emphasis on their practical applications as metal ion sensors, protein receptors, and electrochromic materials.

20. DNA-based biosensors for the detection of molecules in complex matrices and in the body
The project will consist in the development of electrochemical DNA-based biosensors able to monitor molecules in complex matrices. The goal of the project is to monitor small molecules like, chemotherapeutics, antibiotics, drug of abuse or neurotransmitters using aptamer-based biosensors. This sensing platform uses a surface-attached aptamer (a DNA sequence specific for a molecular target) receptor modified with a redox reporter, which, following target recognition can undergo a binding-induced change in electrochemical signal measured using a potentiostat. To test the usefulness of the sensors, sensors are miniaturized and immersed directly in the relevant matrix (i.e., saliva, urine, blood, cerebral spinal fluid, etc.).
Research area, student roles & skills
Research area: Prof.’s Dauphin Ducharme’s research group uses electrochemistry to investigate the interface of biomolecule-modified electrodes in the hopes of developing biosensors. These are notably based on DNA and allow to measure the concentrations of molecules in complex matrices (like blood) and directly in the body to develop new tools for diagnostics and precision medicine (see recent publications : ACS Sensors 2019 4 2832-2837; J. Am. Chem. Soc. 2019 141 1304-1311; J. Am. Chem. Soc. 2017 139 11207-11213).

It will also be required by the student to develop a data analysis script using a simple coding algorithm in Python, Matlab or R. It will be required by the student to prepare vector-designed graphics using software like CorelDraw or Adobe Illustrator to convey the scientific message clearly. It will be required for the student to participate in group meetings by giving presentations and attend local conferences to disseminate the obtained results. Finally, student will be required to undertake a brief literature review to understand the novelty of their project and develop their own ideas.
Skills required: Good laboratory practice are required from the student. Prior laboratory experience is highly sought out. Experience or motivated students to learn electrochemistry, biomolecule handling, fabrication of biosensors and coding (Python, Matlab, R) would be highly desirable.

22. Determining the Molecular Mechanisms of Antibiotic Resistance Garnered by Ribosomal Protection Proteins
Antimicrobial resistance is a growing global crisis with the potential to reach pandemic levels, drawing urgent attention from the biomedical research community. The widespread misuse and overuse of antibiotics in both healthcare and agriculture have accelerated the spread of resistant pathogens, putting us at risk of losing the ability to treat even common infections.
About half of all antibiotics used today target the ribosome—a ribonucleoprotein complex responsible for producing proteins in all cell types, including harmful bacteria. Tetracyclines are a class of antibiotics that bind to ribosomes and block substrate binding, thereby reducing protein production in bacterial pathogens. However, resistance to tetracyclines has emerged through a family of proteins known as Ribosomal Protection Proteins (RPPs). These proteins are thought to confer resistance by removing tetracycline from the ribosome, but this mechanism has not been fully validated and may not apply to all RPPs. Understanding how RPPs mediate tetracycline resistance is a crucial first step toward developing next-generation tetracycline antibiotics that can evade these resistance mechanisms.
This project will involve the overexpression and purification of RPPs from bacterial cells to perform laboratory-based experiments. These in vitro assays will include basic biochemical assays as well as advanced fluorescence-based techniques, such as Förster Resonance Energy Transfer (FRET), to monitor interactions between RPPs and tetracycline. Additionally, we aim to explore the currently unknown structures of these proteins through cryo-electron microscopy to gain a detailed, atom-level understanding of how they function. By developing structures of these proteins in complex with ribosomes we will be able to identify the specific amino acids of the proteins that are critical for tetracycline resistance. These studies are pivotal for developing new strategies to combat antibiotic resistance and help prevent the next potential pandemic.
Research area, student roles & skills
Research area: Antimicrobial resistance is a looming, pandemic-level threat that has garnered the attention of the global biomedical community. Due to the overuse and overprescription of antibiotics in both medicine and agriculture, antimicrobial resistance is flourishing and threatens to make simple infections deadly once again. In the Girodat lab, we study the ribosome—a ribonucleoprotein complex responsible for protein synthesis in all cell types—as it is the target of half of all conventional antibiotics. Our aim is to understand how antibiotics inhibit ribosome function and to characterize resistance mechanisms, ultimately contributing to the development of next-generation antibiotics.
Student roles: During the internship, the student will participate in genetic engineering to modify genes encoding Ribosomal Protection Proteins (RPPs) to enable their overexpression and purification. Overexpression will be induced by adding IPTG, which activates T7 RNA polymerase. The expressed RPPs will then be purified using Ni²⁺-Sepharose affinity chromatography followed by size exclusion chromatography on an FPLC system. Protein quality and purity will be assessed using UV/Vis spectroscopy and SDS-PAGE. Once the RPPs are purified, the student will carry out stopped-flow assays using Förster Resonance Energy Transfer (FRET) between fluorophores attached to components in the system—such as the RPP, ribosome, or tetracycline. This will allow direct measurements of the kinetics and thermodynamics of RPP-mediated tetracycline resistance. Additionally, fluorescently labeled substrates (e.g., mant-GTP) may be used to assess substrate binding and enzymatic turnover, providing insights into how RPPs are regulated. To investigate protein structure, students will work with molecular models of RPPs in complex with ribosomes to evaluate possible interaction sites. Based on these models, specific protein variants can be designed to determine which amino acid residues are essential for RPP function. All activities will be carried out under the guidance of a graduate student in the lab. The graduate student will provide hands-on training for each technique and ensure that the student develops strong laboratory skills and generates reliable, high-quality data.
Skills required: Students should have a basic understanding of biochemistry, including foundational knowledge of protein structure and function, the 20 amino acids, and core lab techniques such as protein purification and SDS-PAGE. They will be expected to maintain a detailed lab notebook and keep accurate records of all experiments. Students will also assist with routine lab duties such as cleaning and sample preparation. Prior hands-on experience with these tasks is not required; all necessary laboratory procedures and assays will be taught as part of the training.
23. Developing an in vitro 3D organoid model for TB infection studies
Supervisor: Neeraj Dhar
University: University of Saskatchewan (Saskatoon campus)
One of the hallmarks of Mycobacterium tuberculosis infection is the aggregation of cells to form structurally organised lesions in the lungs called granulomas. Recent observations have highlighted the extremely heterogenous structural organization of these granulomas wherein the infecting bacteria are exposed to very different microenvironment. It has been postulated that within these microniche environments in the granulomas, subpopulations of M. tuberculosis are able to persist and survive the onslaught of antibiotics and immune responses. Understanding the physiology of mycobacteria surviving in these micro environments will allow us to develop new compounds to target these processes as well as to accelerate the treatment of TB, which is currently one of the huge challenges to global TB control. Currently, we know little about the phenotypic diversity of these subpopulations and their contribution to persistence. While cutting edge techniques such as PET-CT and mass spectrometry have been used to capture the lesion heterogeneity and diverse inflammatory responses within individual granulomas, it was not possible to capture bacterial heterogeneity. Towards this aim we would like to develop a 3d in vitro granuloma model that would allow us to capture host-pathogen interactions at unprecedented resolution in a dynamic manner. Exposing these granulomas to diverse immune regulatory molecules will also help us in generating functionally diverse structures which will help us recreate the different heterogenous lesions observed in vivo. The aims of the proposal are:
1) Use bioprinting or 3d printing approaches to create granuloma like structure in vitro. These can also be functionalized with some kind of vasculature which will allow us to perfuse the structures with neutrophils or T-cells.
2) Carry out high-resolution imaging and characterisation of the in vitro 3D organoids. In addition to high resolution confocal microscopy we can also use electron microscopy imaging to characterise these structures.
Research area, student roles & skills
Research area: Tuberculosis (TB) cased by Mycobacterium tuberculosis is a respiratory pathogen that causes severe complications in the lung and 1.5 million deaths annually. TB can persist in the lung for extended periods of time surviving antibiotic and immune pressures. While several animal models have been developed to study different aspects of host-pathogen interactions, these have severe limitations such as - cost, failure to recapitulate human tissue physiology, availability of reagents etc. Also, capturing the heterogeneity of host-pathogen interactions at the single-cell level is challenging in an animal model. We propose to build an in vitro 3D organoid model to study TB
Student roles: Initially the student will be provided background material and literature related to the research. Then, the student will learn how to plan, design and conduct experiments effectively and how to analyze the data to draw meaningful conclusions. In terms of techniques, the student can expect to be trained in bioprinting, micro fabrication, cell culture and imaging. Once the training period is completed, the student will initiate the project work independently under the immediate mentorship of a senior researcher in the lab. The student will be expected to design and execute the experiments independently and will be presenting the progress or discuss challenges during periodic presentations at lab meetings. During the stay in the lab, the student will not only get to learn the techniques being used in their own project but will be provided opportunities to acquire other techniques such as molecular biology, cloning, compound screening, assay design & antimicrobial discovery etc that are used routinely in our lab. The aim is not only to generate data for this specific project proposed, but to provide a broad exposure to various techniques as well as to showcase the research environment and scientific enterprise. Towards the end of the project the student will provide a written project report including motivation, methodology & conclusions. If the results are significant and reproducible these will be included and written up to be part of a scientific manuscript that will be submitted for publication in peer-review journals with the student listed as an author.
Skills required: The ideal applicant would have some background skills in bioengineering - use of 3d printers or bioinks. Material science, mechanical engineering or biomedical engineering background students are also welcome. Experience with cell culture techniques or imaging techniques would also be an asset. The student should be familiar with online repositories for scientific articles and how to source relevant background literature for reading up on the project and to be updated with the recent developments in the field.
24. Development and Evaluation of Multifunctional Implant Coatings for Porous Additively Manufactured Bone Implant Biomaterials
The research project focuses on the development and assessment of bioactive coatings for porous, additively manufactured titanium scaffolds for bone applications. Conventional metallic implants often face challenges, including poor osseointegration, infection, wear, and stress shielding, which are further compounded in diseased conditions such as osteoporosis (OP), which affects +2M Canadians. To address this, the Regenerative Biomaterials Innovation Group (RBIG) focuses on engineering biomimetic porous implant solutions with enhanced surfaces to improve peri-implant bone repair to meet patient-specific needs. The proposed project aims to investigate new multifunctional surface strategies developed to improve implant bio-functionality and peri-implant bone regeneration in both healthy and OP conditions.
The project is designed for two undergraduate researchers working collaboratively on complementary objectives. One will focus on developing and evaluating electrochemical layer-by-layer coating strategies for porous scaffolds using bioactive agents such as strontium and hydroxyapatite, among others. They will explore how tunable coating architectures and ion-release profiles can enhance surface bioactivity and better mimic the hierarchical structure of bone. The second will focus on the mechanical and surface assessment of coated scaffolds, including tribological behaviour and coating stability under physiologically relevant conditions. They will contribute to evaluating how surface modifications influence mechanical durability and implant surface interactions.
Both students will collaborate with graduate students within the RBIG and receive interdisciplinary training in state-of-the-art biomaterials and multiscale characterization techniques. Surface morphology, chemistry, and topography of coatings are planned to be assessed using laser profilometry, atomic force microscopy, scanning electron microscopy, energy-dispersive X-ray spectroscopy, and contact angle measurement techniques. Students will also contribute to in vitro biocompatibility workflows using osteoblast cell models to evaluate cell adhesion, proliferation, and metabolic activity relevant to bone regeneration.
Overall, this project will support the development of next-generation biomaterials with improved implant integration and long-term performance for orthopedic and dental applications.
Research area, student roles & skills
Research area: My research focuses on the design and multiscale characterization of biomaterials for hard tissue applications, including bone and dental implants. I develop biomimetic, patient-specific implant systems using additive manufacturing and bioactive surface engineering strategies to improve osseointegration and tissue repair. My work uniquely integrates advanced characterization techniques, including electron microscopy, liquid-phase microscopy, micro-CT, and mechanical analysis, to investigate biomineralization processes and the structure-function relationships of biomaterials across nano- to macro-length scales. Through this work, I aim to advance next-generation regenerative biomaterials and improve the performance and longevity of biomedical implants.
Student roles: The undergraduate researchers will join the RBIG to support ongoing projects focused on biomimetic implant design and bioactive surface engineering for bone repair applications. Students will work collaboratively with graduate trainees and their faculty mentor on projects involving porous additively manufactured titanium scaffolds, multifunctional coatings, and multiscale biomaterials characterization. One student will primarily focus on the development and optimization of bioactive electrochemical coating strategies for porous scaffolds, including coating synthesis, surface functionalization, and assessment of coating morphology and chemistry. The second student will focus on the mechanical and surface evaluation of coated scaffolds, including tribological assessment, mechanical testing, and analysis of coating stability under physiologically relevant conditions. Both students will gain hands-on experience with advanced characterization techniques, such as scanning electron microscopy, energy-dispersive X-ray spectroscopy, laser profilometry, atomic force microscopy, contact angle measurements, micro-computed tomography, among other techniques, pending project progress and needs. Students may also contribute to in vitro biomaterials workflows involving osteoblast cell culture to assess cytocompatibility and bone regeneration responses. Additional responsibilities may include data analysis, image processing, literature reviews, workflow development, preparation of laboratory documentation and standard operating procedures, and supporting collaborative laboratory activities. Students will receive interdisciplinary training in biomaterials, additive manufacturing, microscopy, and biomedical engineering research methods while contributing to the development of next-generation implant technologies. Overall, students will be supported through a unique international research exchange opportunity designed to foster professional growth, interdisciplinary research training, and cultural enrichment. In addition to developing technical and laboratory skills, students will strengthen their scientific communication, collaboration, and critical thinking abilities through regular team interactions and by presenting a summary of their research outcomes to the RBIG at the conclusion of the internship.
Skills required: Applicants should have a background in engineering, materials science, biomedical engineering, biology, or a related discipline, with strong motivation and organizational skills. Interest in biomaterials, bone research, surface engineering, or biomedical implants is encouraged. Previous exposure to materials characterization, microscopy, mechanical testing, CAD, electrochemistry, or in vitro cell culture would be considered an asset, but is not required. Prior research experience is beneficial; however, comprehensive training and mentorship will be provided within the RBIG. Students should be enthusiastic about interdisciplinary research and collaborative teamwork in a laboratory environment.
The goal of this research program is to de-risk the long-term goal of providing safe and efficient gene therapy to Neurofibromatosis Type I patients. Neurofibroma is a tumor type that manifested in Neurofibromatosis Type I patients with 99% penetrance. In addition to the important psychosocial consequence, these disfiguring tumors can severely affect mobility and day-to-day life. Surgery is the only treatment option but is not practical when facing hundreds of tumors or innervating a vital organ in a deep location. Gene therapy (i.e. to restore the function of a defective gene) is an attractive way to cure Neurofibromatosis Type I manifestations such as neurofibromas. Sequencing Schwann cells from neurofibroma reveal that NF1, a tumor suppressor gene, is the only gene mutated in multiple samples, and hence a monogenic disease highly suitable for gene therapy. Here, we propose to proof-of-principle NF1 gene therapy in a mouse model and test NF1 gene therapy in human Schwann cells from NF1 patients in vitro and in vivo.

26. Development of Lignin-Based Adhesives: Adhesive Performance and Panel Properties
As mentioned before, this project aims to develop sustainable, formaldehyde-free adhesive systems for wood-based panels, addressing the need to reduce hazardous emissions while maintaining high industrial performance. Conventional adhesives used in wood panels rely heavily on petroleum-derived resins that release formaldehyde, posing environmental and health concerns. In response, this research focuses on valorizing lignin, an abundant aromatic biopolymer obtained as a by-product of pulping and biorefinery processes, as a renewable alternative feedstock. A central challenge in using lignin for adhesive applications lies in its structural heterogeneity and limited reactivity. To overcome these limitations, the project employs targeted depolymerization and chemical functionalization strategies to enhance lignin’s reactive sites and improve its compatibility with other formulation components. These modifications are designed to tailor the physicochemical properties of lignin, enabling its effective integration into adhesive systems with improved bonding performance.
The research adopts a multidisciplinary approach, integrating principles from wood science, polymer and organic chemistry, and chemical engineering. It involves the synthesis of lignin-based adhesive formulations, followed by comprehensive characterization using techniques such as thermal analysis, spectroscopy, and mechanical testing. Particular attention is given to evaluating adhesive performance through parameters such as internal bond strength, durability, and resistance to moisture, ensuring that the developed systems meet or exceed existing industrial standards.
In addition to performance optimization, the project emphasizes environmental impact reduction by minimizing toxic emissions and promoting the use of renewable resources. By advancing lignin-based adhesive technologies, this work contributes to the development of eco-efficient materials and supports the transition toward a circular bioeconomy. Ultimately, the project seeks to provide viable, scalable alternatives to conventional adhesives, aligning sustainability goals with the practical requirements of the wood products industry.
Research area, student roles & skills

27. Development of Optical Nanosensors for Machine Learning-Driven Sensing and Biomedical Diagnostics
Sepsis and antimicrobial resistance (AMR) account for over 190 million deaths globally, yet rapid diagnostic tools for both conditions are underdeveloped. This project will develop field-deployable, surface-enhanced Raman scattering (SERS) nanosensors for monitoring sepsis in biofluids and tracking AMR through the following steps. Step 1: Gold/silver nanoparticles will be synthesised via chemical reduction. The pre-synthesised nanoparticles will be immobilised onto glass or silicon substrates using a block copolymer templating architecture to create nanosensors with dense, reproducible, periodic nanostructures on the sensor surface. Optimisation of nanostructure morphology, physicochemical properties, and polymer molecular weight will be performed to maximise the performance of our nanosensors. Step 2: Nanosensors will be characterised using UV/vis extinction spectroscopy to assess plasmonic characteristics, dynamic light scattering to probe surface charge, computer simulations to visualise the distribution of electric fields generated by periodic plasmonic nanostructures, electron microscopy (transmission and scanning) to investigate nanostructure morphologies, and Raman spectroscopy to examine and optimise the analytical performance (e.g., sensitivity, specificity, limit of detection) of the nanosensors. Step 3: SERS nanosensors developed in step 2 will be used for (i) quantitative detection of sepsis biomarkers directly in serum and sweat samples, and (ii) monitoring bacterial response to antibiotics (e.g., penicillin, carbapenems) to create a new analytical platform for rapid and unequivocal antibiotic susceptibility testing (AST). Before this, nanosensors will be calibrated in pristine buffer solutions and spiked samples, and subsequently validated in real biological samples to ensure reliable performance. Analytical measurements will be conducted using a portable Raman spectrometer equipped with a 1-metre-long fibre optic probe. SERS spectra will be processed using machine learning algorithms to achieve both regression and classification of target biomarker characteristics. A combination of small sensors and a portable Raman device represents a novel approach ideally positioned for point-of-care detection of sepsis and susceptibility testing in underserved communities.
Research area, student roles & skills
Research area: My group works at the intersection of plasmonic nanomaterials, spectroscopy, and machine learning to address unmet needs in (bio)sensing and health. In particular, we develop plasmonic nanoparticles and surface-chemistry strategies, and seek to optimise light-matter interactions at the nanoscale to create first-in-class Raman spectroscopy-based nanosensors that can efficiently and rapidly enable disease diagnostics, therapeutic monitoring, and environmental surveillance. Recognising that Raman measurements generate large multivariate spectral datasets, we develop robust chemometric and machine-learning models that transform complex spectral data into easy-to-interpret outputs, thereby enhancing the reliability and integrity of our optical nanosensors.
Student roles: The student's roles will be to (1) synthesise nanomaterials of various morphologies using our established standard operating protocols/guidelines: first, the student will synthesise and optimise the plasmonic properties of isotropic (e.g., nanospheres) and anisotropic (e.g., nanostars, multibranched urchin-like nanostructures) nanoparticles at excitation wavelengths of 633 and 785 nm. The best-performing nanoparticles will be used to develop optical nanosensors. (2) Develop optical nanosensors from pre-synthesised nanoparticles and polymer-templating strategies: here, the student will take a leading role in designing surface chemistry strategies, starting with pH modification of nanoparticles and creating self-assembled monolayers (e.g., dip coating, interfacial assembly) of pH-normalised colloidal nanoparticles on polymer-templated curved substrates (capillary) and flat chips (silicon). (3) Characterise nanosensors using various analytical tools: in collaboration with a graduate student, the student will investigate plasmonic properties (using UV/vis and computer simulations), surface chemistry (using zeta potential), and morphological dynamics (using electron microscopy) of nanosensors created in step 2 above. (4) Optimise the performance of nanosensors for the detection of disease biomarkers and antimicrobial resistance in real samples: the student will work with lab members to design and perform experiments for molecular (bio)sensing in complex samples (e.g., serum), optimise instrumental parameters for spectral acquisition, and process and interpret spectral data. The student will be encouraged to share project findings at the Department of Chemistry Undergraduate Summer Poster Fair held at Dalhousie University and other conferences [e.g., 2027/26 Undergraduate Chemistry Conference (ChemCon) held in Atlantic Canada] that align with student academic developmental stage. Our goal is to mentor students in developing high-quality technical and transferable skills. Accordingly, the student will be trained by the supervisor and graduate students and provided with foundational in-house SOPs at every stage of the project. The student will also be supported and encouraged to explore other experimental avenues aligned with their interests throughout the project.
Skills required: Our project is interdisciplinary, and students with backgrounds in chemistry, biochemistry, biology, microbiology, or physics are welcome. Students from these disciplines who are motivated and passionate about developing new skills in one or more of the following areas (1) nanomaterials/chemical synthesis (e.g., nanoparticles or other molecular structures), (2) surface chemistry, (3) spectroscopy, and (4) machine learning are welcome to join us at Dalhousie University. Our lab has well-trained, collegial graduate students, a supportive environment and principal investigator (supervisor), and resources to nurture and support effective training and mentorship for new undergraduate students from any physical, biomedical or biological science discipline.
28. Development of a Bio-Based Additive for Ski Waxes from Industrial By-Products
This project aims to assess whether an industrial by-product derived from the transformation of a natural material can be used as an additive in ski waxes. This by-product exhibits good hydrophobic properties and has a very low environmental impact, making it a promising candidate for the development of more eco-friendly wax formulations.
The project is divided into two complementary phases. The first focuses on defining the best method for incorporating the additive into a ski wax, by testing different blending and shaping approaches. The second phase aims to compare the resulting formulations with existing performance waxes, evaluating friction reduction and durability using specialized laboratory equipment.
Depending on the results, this new bio-based additive could be used as a high-performance wax or as an eco-friendly alternative to training and recreational waxes, contributing to reducing the environmental footprint of skiing.
Research area, student roles & skills
Research area: My research focuses on the chemistry and performance of wood finishing products, bio-based adhesives and coatings, and wood modification and impregnation. I develop innovative valorization strategies for biomass residues, including the development of functional bio-based materials with controlled surface properties. I also work on hydrophobic and stimuli-responsive coatings. As Director of the Centre de recherche sur les matériaux renouvelables (CRMR) and holder of the NSERC-Canlak Industrial Research Chair in Interior Wood Finishing, my work bridges fundamental chemistry and the development of sustainable materials for various industries.
Student roles: The student will play an active role throughout the entire project by contributing to the design, execution and analysis of the experiments, under the supervision of a research professional who will provide hands-on training in laboratory techniques and safety procedures. In the first phase, the student will contribute to the development of the experimental protocol in collaboration with the research team, and will prepare ski wax formulations incorporating the industrial by-product under study. The student will work to define the best method for incorporating the additive into the wax, testing different blending and shaping approaches. In the second phase, the student will conduct laboratory tests using specialized equipment to evaluate the performance of the different formulations, particularly in terms of friction reduction and durability, and will compare the results with those of existing performance waxes. Beyond experimental work, the student will be expected to collect, analyze and interpret the data, maintain rigorous laboratory records, and contribute to the writing of scientific reports. The student will present results at regular lab meetings and will collaborate closely with other members of the research team. This position offers training at the interface of materials chemistry, surface properties and circular economy, with potential applications for both performance waxes and recreational and training use.
Skills required: The ideal candidate holds a background in chemistry or materials science, particularly in areas such as polymers, additives and surface properties. The student should understand key physical concepts such as friction, hydrophobicity and durability, and be familiar with laboratory techniques and experimental design. The student must be capable of designing and following a testing protocol, using laboratory equipment, and preparing and blending material samples. Strong analytical and writing skills and autonomy are expected. Experience with skiing and ski waxing would be considered an asset.
29. Development of a Click/Diels-Alder/Carbene sequence: towards the synthesis of sesquiterpenoids. / Développement d’une séquence Click/Diels-Alder/Carbène : vers la synthèse de sesquiterpenoïdes.
Ptaquilosin and illudins (sesquiterpenoids) have been isolated from plants and fungi,
demonstrating their antitumoral and carcinogenic properties. Humans can be directly exposed to ptaquiloside (a form of ptaquilosine with a glucose unit at position 3a) due to its presence in ferns via consumption of the plant, contaminated water or milk from cattle that have eaten the plant. It is therefore essential to develop an efficient chemical synthesis for two major reasons: 1) the need for analytical standards for its dosage and 2) the study of its potential danger to humans, which has been little known until now. The development of a common polyvalent synthesis for ptaquilosin and illudins would enable us to understand their respective modes of action, and then prepare structural derivatives. We therefore propose to develop a Click/Diels-Alder/Carbene sequence and apply it to the synthesis of precursors for ptaquilosin and illudins A and B. The aim of this research project is to develop the second step in the Click/Diels-Alder/Carbene sequence, i.e., the formation of Diels-Alder adducts between vinyl-triazoles and alkenes. Reaction conditions will be optimized using model precursors. Various vinyl-triazoles will be synthesized to prepare a library of Diels-Alder adducts.
Research area, student roles & skills

Student roles: The intern will work 35 to 40 hours per week on the project: literature search and preparation of experiments, laboratory manipulations, data analysis, interpretation and presentation of results. Research tools and reference management software (e.g., Scifinder and EndNote) will be used to study the literature. Classical and modern synthesis (organic and inorganic) and characterization techniques will be studied and applied.

The intern must be able to work both independently and as part of a team, and have good communication skills.
30. Development of a new antibody array for multiplexed bioassays towards cancer diagnostics
Cancer is a complex disease and requires the study of multiple molecules to provide a more comprehensive view of its nature. In light of its complexity, microarray technology has become a powerful tool in cancer studies. Thousands to tens of thousands of miniaturized bioassays can be conducted in parallel on a single chip, enabling high-throughput measurement of biomolecules. However, conventional antibody microarrays have a size limitation of each micro-spot of at least ~ 100 μm in diameter. This size limitation restricts assay throughput and sensitivity, which is usually required for early diagnosis.
We will develop and implement a micro-fabrication process to bring down the size limitation of antibody microarrays, achieving a 1-10 μm range for the size of each spot. Multiple parameters will be optimized to create uniform microarray spots with good spot morphology in large areas. After that, the fabricated antibody microarray will be used for highly sensitive multiplexed cancer protein quantification. The project will make the microarray technology suitable for highly sensitive cancer protein measurement, enabling its broader application for early diagnosis.

Research area: Dr. Huiyan Li directs the BioMed Innovation Lab at the University of Guelph, Canada. Our multidisciplinary research focuses on developing innovative micro-and nano-biosensors, with an emphasis on microarray technologies for early cancer diagnosis.

We have applied these technologies for the discovery of protein biomarkers in blood samples, shining a light on early non-invasive cancer diagnosis. Collectively, these efforts will eventually contribute to personalized cancer management, improving patient outcomes.
Student roles: One student will be recruited to conduct this research. They will get hands-on skills on micro-fabrication, soft lithography, and protein and cellular assays. The students will optimize the microarray fabrication process to obtain homogeneous micro-spots across a relatively large area on microscope slides. They will characterize the obtained antibody microarray in terms of spot size, morphology, spot-to-spot spacing and uniformity using optical and electron microscopes available on campus. The students will then learn use the developed microarrays to conduct protein and cell analysis from cancer samples.
In terms of communication and leadership, the students will work closely with Dr. Li’s team members and our collaborators at the University of Guelph, including cancer clinicians and those from the Department of Chemistry. The students will have the opportunity to become the contact persons for these collaborations and participate in regular project meetings to report the research progress and remove roadblocks. They will also polish oral and written communication skills by making presentations to the whole research group and writing progress reports and potential publications.
By completing the project, the students will gain multidisciplinary knowledge and learn the state-of-the-art technologies in micro-technology, immunoassays, protein/cell techniques, and cancer biology. The student will also improve communication skills and leadership in an open, dynamic, and highly collaborative research environment.
Skills required: Students with a general academic background in biochemistry, biological sciences, biological/biomedical engineering, or chemistry are welcome. The selected students are expected to have the basic knowledge to understand or learn the microfabrication process and bioassays. The ability and commitment to learn hands-on skills during the project, such as micro-fabrication, soft lithography, and protein and cellular bioassays, are desired. The students are also expected to be able to communicate effectively in a collaborative team environment.

32. Development of a new treatment for inflammatory bowel disease (Crohn's, Colitis)
According to the trainee's interest, up to 3 trainees can work on some of the 4 aspects below.
1) Determine if and how the blockade of the P2Y receptors in intestinal epithelial cells (IECs) prevents inflammation in 2 mouse models of mucosal inflammation that most resemble human IBD, i.e., the adoptive T cell transfer model of colitis and the Dextran Sulfate Sodium (DSS) models. We will intra-rectally administer different types of blockers of the P2 receptors expressed at the surface of IECs, such as a scavenger of general P2 receptor ligands (apyrase) or specific antagonists of P2Y1, P2Y2 and P2Y6, and determine their impact on the inflammatory responses in these 2 IBD models. In the DSS model we will also use deficient mice for these receptors and use bone marrow transplantation experiments to discriminate a role of the receptors expressed on both leukocytes and IECs. Preliminary results with the DSS model show that engagement of both P2Y2 and P2Y6 receptors in IECs lead to the inflammation.
2) Define molecular mechanisms by which P2Y receptors control intestinal inflammation using primary IECs from WT mice as well as from P2Y2 and P2Y6 KO mice. We will focus on examining the synthesis and release of cytokines as well as cell permeability. These experiments will also be performed with IECs purified from healthy sections of the colon from human patients.
3) Engineer a soluble form of NTPDase8 as a potential treatment for IBD, and test it in the IBD mouse models detailed above.
4) Test new P2Y receptor antagonists developed for application in humans, as a potential treatment for IBD, using the IBD mouse models detailed above.
Research area, student roles & skills
Research area: Inflammatory bowel diseases (IBD: Crohn’s, colitis) affect a large number of people. New-targeted treatment options are needed. We recently identified that endogenously produced nucleotides induce intestinal inflammation by activating P2Y receptors in intestinal epithelial cell (IECs). We discovered that the ectonucleotidase NTPDase8 prevents inflammation by hydrolysing nucleotides at the luminal surface of the intestine (Gut, 2022; Impact Factor: 32), and that blocking the binding of nucleotides to P2Y receptors also prevents inflammation.
A better understanding of nucleotide signaling in the gut could lead to the identification of novel therapeutic targets to treat IBD.

Student roles: The trainee will execute the project detailed above under the supervision of the PhD/post-doc student responsible for the assigned project. Variation of the project to the desire of the trainee will be discussed.
All the techniques used by the trainee are routinely performed in my laboratory. This project is therefore ideal for the training of a young an ambitious trainee as if the work is well done it will lead to a least a paper where the trainee will participate as a co-author.
Skills required: Background in pharmacology, biochemistry, cell culture, mouse models, inflammatory bowel disease (IBD), in both theory and practice would help but are not mandatory.
33. Development of antibacterial functional melamine laminates for particleboard surfaces
The objective of this project is to develop antibacterial functional melamine laminates for particleboard surfaces through the modification of melamine-formaldehyde (MF) resin systems used in decorative laminates. Melamine-laminated particleboards are widely used in furniture, schools, hospitals, and public environments because of their durability, chemical resistance, and easy-to-clean surfaces. However, conventional MF laminates do not possess intrinsic antibacterial properties.
This project investigates the incorporation of bio-based antibacterial agents, polymeric latex matrices, and inorganic functional carriers into MF resin systems in order to develop durable antibacterial laminated surfaces while preserving important industrial properties such as optical appearance, curing behavior, abrasion resistance, and surface durability.
The methodology includes the formulation of modified MF resin systems, impregnation of decorative papers, and short-cycle lamination to produce functional antibacterial laminates. The project also involves the characterization of formulation stability, surface properties, and antibacterial performance. Characterization methods may include FTIR analysis, viscosity and rheological measurements, optical evaluation, and antibacterial testing according to ISO 22196.
This research is carried out within the framework of the Corepan-Bois industrial research consortium in collaboration with industrial partners involved in engineered wood panels and advanced laminated surface technologies.

34. Development of low-cost multiplexed bioassays for early cancer diagnostics
Cancer is a complex disease and requires the study of multiple molecules to provide a more comprehensive view of its cause and nature. In light of its complexity, microarray technology has become a powerful tool in cancer studies. Thousands to tens of thousands of miniaturized bioassays can be conducted in parallel on a single chip, enabling high-throughput measurement of biomolecules. Among those molecules, proteins are of particular interest, because they are the nanomachines of life and can directly provide pathological information at the functional level. Antibody microarrays contain arrays of antibodies, with each spot ~100 micrometers in size. They have been used to measure tens to hundreds of proteins simultaneously. Although powerful, antibody microarrays are not widely accessible to most laboratories, largely due to the need for expensive equipment such as a fluorescence microarray scanner for fluorescence signal acquisition.
To address this problem, we will develop a loc-cost antibody microarray-based assay, with the assay signals detectable using a conventional flatbed document scanner. The project will reduce the equipment cost by 50-100 folds, thus making the microarray technology widely accessible for most laboratories. A sandwich immunoassay format will be adopted for highly sensitive and specific protein measurement. Specifically, primary antibodies will be arrayed on a glass slide using a microarray spotter. Then, secondary antibodies will be applied after incubation of biological samples (e.g., blood plasma). Several strategies for developing colorimetric signals will be investigated. The assay sensitivity and reproducibility will be compared with conventional fluorescence-based assays. This project will pave the way for low-cost microarrays, enabling their wider application in both research and clinical labs.

35. Development of microencapsulation processes and polymeric carriers for the protection of bioactive natural extracts in food applications
The project aims the development of nanoemulsions for the preservation of bio-based or natural antimicrobial/antioxidant extracts, for applications in fruits/vegetables, meat or cheese products. Microencapsulation techniques with bio-based polymers will be also implemented to increase the stability, bioactivity and controlled release of the bioactive natural extracts (plant extracts, metal nanoparticles) during storage. The resulting bioactive devices will be applied on fruits/vegetables, meat and cheese products.
Objectives:

4) Develop different polymeric carriers such as bioactive flexible packaging films, coatings, microparticles, diffusion patches or absorbent pads.
5) Evaluate the in situ antimicrobial capacity of bioactive devices in food products. We will evaluate the inhibition of foodborne pathogens in food systems (challenge tests) and the shelf-life.
6) Evaluate the physicochemical properties of food (color, texture, sensory analysis).
Methodology:
The selection of surfactants, study of emulsion stability, viscosity, texturometry, colorimetry, the preparation of nanoemulsions and their incorporation into polymers will be performed based on methods developed in our laboratory. Structure analysis of the formulations will be performed by FTIR spectroscopy and SEM/TEM microscopy. The polymeric carriers will be characterized for their mechanical, barrier, structure and physicochemical properties. The bioactive loading and encapsulation efficiency will also be measured. Sensory evaluation and microbiological analyses (challenge tests with pathogens and shelf-life of food products) will be done for application purposes.

36. Development of strategies to neutralize Cryptococcuus neoformans.
Our research focuses on the unique biology of two yeasts: Schizosaccharomyces pombe and Cryptococcus neoformans. Both yeasts serve as model systems to investigate how saprophytic and pathogenic yeast cells acquire exogenous heme. In the case of S. pombe, this tractable model allows the use of the power of genetics to selectively block heme biosynthesis, setting conditions to investigate the mechanisms by which external heme is taken up by cells, and subsequently distributed to hemeproteins such as Yhb1. The goal of this research is to gain a better understanding of key mechanistic aspects regarding how Yhb1 and its ortholog Fhb1 in C. neoformans become active in a heme-dependent manner, conferring resistance to NO. This information will contribute to our long-term goal of identifying new strategies to overcome NO resistance mediated by Yhb1 and Fhb1, thereby improving the treatment of infections caused by fungal pathogens.
Research area, student roles & skills
Research area: Heme has a wealth of functions in biological systems, making it an essential micronutrient for all living organisms. Defects in heme homeostasis are directly responsible for diseases, and have been tied to impaired development, metabolic syndromes and fungal virulence. Consequently, it is critical to gain a
comprehensive understanding of the molecular bases of heme-dependent proteins in living systems.
The research project will use a model system to decipher the interplay between important proteins involved in heme acquisition. Furthermore, inhibitors will be tested as potential anti-fungal drugs against heme-dependent proteins as they are required for invasion of Cruptococcus neoformans cells.
Student roles: The student will be involved in a research projet in which he/she will have to apply molecular and cellular approaches to perform biological experiments. The student will develop her/his own sub-project to gain independence and autonomy skills.
The students involved in the proposed research program will learn a broad spectrum of experimental approaches, including new proteomics strategies and several applications involving next generation sequencing for genome-wide analysis of gene expression changes. Although each student will primary work on a specific aim, collaboration between students will be highly encouraged to ensure that they gain mastery over all the laboratory methods.
Each week, we have a: Lab meeting: a member describes her/his results and experimental problems in order to exchange ideas and receive constructive criticism. Journal club: to discuss and comment publications relevant to our field or other areas.
Departmental group seminar: the graduate students are exposed to "tell a story" and exchange about their results with other graduate students and professors of the Department.
Skills required: Highly interested student who is eager to learn molecular and cellular biology as well as yeast genetics. New generation sequencing (NGS) approaches (e.g. RNA-Seq) will be used and a combination of bioinformatics tools will be available for the trainees.
37. Drinking with Mary Jane: Effects of prenatal cannabis and alcohol on the developing brain.
Our goal is to quantify the effects of Cannabis and Alcohol, alone and in combination, on brain structure and function. Because of the high susceptibility of the hippocampus to alcohol as a teratogen, and the high density of cannabinoid receptors found in the hippocampus, we hypothesize that combined exposure will dramatically affect neuronal structure and function in this region. Because both alcohol and cannabis have sex specific effects, we hypothesize the effects will be more prominent in males and compounded by combined use.
Research area, student roles & skills
Research area: We study a variety of forms of neuroplasticity, including synaptic plasticity, metaplasticity, and neurogenesis, to better understand how brain development is affected by prenatal challenges. Trainees in the laboratory have the ability to work with animal models that include those for prenatal cannabis and ethanol exposure to better understand how learning and memory processes are impacted and examine different interventions for their therapeutic potential. Our laboratory places a strong emphasis on trainee development and supports equity and diversity initiatives both in the lab and in trainee activities outside of the lab.
Student roles: The student will assist either a post-doctoral fellow or a graduate student by conducting an independent project during their time in the laboratory. Students should be self-motivated and will be provided with instruction and the support needed to complete the project.
Skills required: Basic biochemistry/biology/histology skills are preferred. Individuals with electrophysiology, microscopy, biochemistry, or immunohistochemistry experience are encouraged to apply.
38. Développement de pâtes à mouler à base de résidus de pommes de terre pour la fabrication d'emballages alimentaires
Potato is the most widely grown vegetable in Quebec, with production of approximately 648,000 tonnes and revenues of 245 million dollars. However, the industry generates significant post-harvest losses estimated at around 64,800 tonnes per year. These residues, rich in starch and water, remain largely underutilized and represent an economic and environmental burden for producers and processors.
This project aims to valorize these residues by transforming them into molded food packaging such as plates, egg cartons and ready-to-eat meal containers, by adapting cellulosic pulp molding and thermoforming technology. The work will focus on the characterization of residues as raw material, the study and comparison of different pulping processes including low water consumption approaches, the development and optimization of pulp formulations adapted to thermoforming, and the evaluation of the mechanical and barrier properties of the resulting packaging according to industry standard methods.
The current context is highly favorable: prohibition of harmful substances in imported food packaging, growing demand for local alternatives to wood fibers, expansion of e-commerce and ready-to-eat meals, and government policies on responsible residual materials management. The Canadian molded pulp market generated 185 million US dollars in 2025, and the non-lignocellulosic fiber segment is expected to become the most lucrative by 2033.
This project will provide the student with high-level multidisciplinary training at the interface of biomaterial chemistry, pulping processes and circular economy, within a collaborative environment bringing together Innofibre, industrial partners and the Quebec potato industry. Expected outcomes include the reduction of organic waste, the creation of new revenue streams for producers and a concrete contribution to the sustainable development of the sector.
Research area, student roles & skills

Student roles: The student will contribute to the development of molding pulps from potato residues, in close collaboration with Innofibre and the industrial partners of the project. All experimental work will be conducted under the supervision of a research professional, ensuring proper training in laboratory techniques and safety procedures. The student will first carry out the physicochemical characterization of potato residues used as raw material, including downgraded potatoes and peels from processing operations. The student will then study and compare different pulping approaches, including low water consumption methods, and will participate in the development and optimization of pulp formulations adapted to the thermoforming process, varying residue proportions, fiber types and additives. Finally, the student will evaluate the performance of the resulting packaging, including mechanical and barrier properties, according to industry standard methods and in relation to food contact requirements. Beyond experimental work, the student will be expected to actively participate in data analysis and interpretation, maintain rigorous laboratory records, and contribute to the writing of scientific reports and publications. The student will present results at regular lab meetings and at scientific conferences, and will collaborate closely with other members of the research team. This position offers high-level multidisciplinary training at the interface of biomaterial chemistry, pulping processes and circular economy, within a collaborative environment bringing together a technology transfer center, industrial partners and the Quebec potato industry.
Skills required: The ideal candidate holds a background in chemistry, chemical engineering, materials science, food science, or a related field. Familiarity with material characterization, pulping processes or bio-based packaging is an asset. Experience with mechanical and barrier property testing techniques is welcome but not required, as training will be provided. The student should demonstrate strong analytical and writing skills, autonomy, and a genuine interest in circular economy principles and the valorization of agro-industrial residues. Proficiency in French is required, and a good reading knowledge of English scientific literature is expected.
39. Electrochemiluminescent Biosensor Platform for Detection of Leukemia Biomarkers
Supervisor: Anna Ignaszak
University: Brock University (St. Catherines campus)
Leukemia remains one of the most aggressive hematological malignancies, where early diagnosis and continuous disease monitoring are critical for improving patient survival and therapeutic outcomes. Current diagnostic methods, including polymerase chain reaction (PCR), flow cytometry, ELISA, and immunohistochemistry, often require centralized laboratories, expensive instrumentation, trained personnel, and lengthy analysis times. Electrochemiluminescent (ECL) biosensors offer a transformative alternative by combining electrochemical excitation with light-emitting reactions to achieve ultrasensitive, rapid, and minimally invasive biomarker detection. Recent studies have demonstrated femtomolar and attomolar detection limits for leukemia-associated fusion genes and miRNAs using nanomaterial-enhanced ECL platforms.
The objective of this research is to develop a multiplex electrochemiluminescent biosensor capable of detecting leukemia-related biomarkers, including BCR/ABL fusion genes, leukemia-associated miRNAs, and circulating tumor cells (CTCs), directly from serum or whole blood samples. Specific objectives include: (1) fabrication of nanostructured ECL electrodes with enhanced luminophore loading and electron transfer efficiency; (2) integration of aptamer- and nucleic acid-based recognition elements for selective biomarker capture; (3) incorporation of signal amplification strategies such as rolling circle amplification, catalytic hairpin assembly, and DNA walkers to improve sensitivity; and (4) validation of the platform using clinically relevant samples and comparison against conventional analytical methods.
The methodology will involve modification of gold or carbon screen-printed electrodes using conductive nanomaterials such as Au nanoparticles, MXenes, graphene derivatives, or covalent organic frameworks to enhance ECL intensity and analytical stability. Ruthenium complexes or luminol-based ECL systems will be immobilized onto the electrode surface. Biomarker-specific aptamers and DNA probes targeting BCR/ABL fusion genes and leukemia-associated miRNAs will be conjugated using thiol-gold or EDC/NHS surface chemistry. For CTC detection, multivalent aptamer recognition combined with magnetic enrichment strategies will be implemented.
Signal amplification will be achieved through DNA-based amplification circuits and nanozyme-assisted catalytic cascades to maximize photon generation per captured target.

Research area: Dr. Anna Ignaszak is an expert in electrochemical biosensor technologies with over 20 years of experience in electrochemistry, analytical chemistry, and biomedical diagnostics. Her research focuses on the development of portable and ultrasensitive biosensing platforms for detection of cancer, infectious disease, inflammatory biomarkers, and environmental contaminants. She has extensive expertise in electrochemical impedance spectroscopy (EIS), voltammetric sensing, electrochemiluminescence, nanomaterial-modified electrodes, and biomolecular surface functionalization. Dr. Ignaszak integrates advanced materials, microfabrication, and computational modeling to design high-performance point-of-care diagnostic devices. Her work emphasizes translation of electrochemical sensor technologies toward clinically relevant, field-deployable, and commercially scalable healthcare applications.
Student roles: Two students will work in parallel on a shared electrochemiluminescent biosensor platform for leukemia biomarker detection, using the same portable potentiostat/ECL reader, screen-printed electrode cartridge, optical detector, and assay workflow. Student 1 will focus on BCR-ABL fusion gene detection, a clinically important marker of chronic myeloid leukemia. This student will design and optimize DNA capture probes immobilized on nanomaterial-modified gold or carbon screen-printed electrodes. The work will include electrode functionalization, hybridization assay development, optimization of luminol- or Ru-complex-based ECL signal generation, and evaluation of analytical performance using synthetic BCR-ABL sequences and serum-spiked samples. Key tasks will include improving selectivity against mismatched DNA, lowering the detection limit, and validating reproducibility across electrode batches. Student 2 will focus on leukemia-associated microRNA detection, such as miR-10a-5p or miR-16, relevant to acute myeloid leukemia and broader leukemia monitoring. This student will develop an ECL assay using complementary nucleic-acid probes, aptamer-assisted recognition where applicable, and signal amplification strategies such as rolling circle amplification, catalytic hairpin assembly, or DNA-walker systems. The assay will be optimized for detection in diluted serum or plasma, with emphasis on sensitivity, anti-interference performance, and stability. Both students will use the same hardware architecture to ensure platform compatibility and future multiplexing. Shared tasks will include electrode pretreatment, nanomaterial coating, ECL reagent optimization, calibration-curve generation, limit-of-detection analysis, selectivity testing, and comparison with standard molecular diagnostic benchmarks. The students will also jointly develop standard operating procedures for cartridge fabrication, sample handling, and data analysis. This coordinated project will generate two marker-specific assays on one common ECL biosensing platform. The outcome will be a modular diagnostic system capable of detecting both genetic and RNA leukemia biomarkers, supporting future multiplex point-of-care testing for early diagnosis, treatment monitoring, and minimal residual disease assessment.
Skills required: Students working on this electrochemical biosensor project should have a background in chemistry, biochemistry, biomedical engineering, materials science, or related disciplines.

Full training in electrochemical methods, biosensor fabrication, analytical techniques, data analysis, and scientific communication will be provided throughout the project to ensure student success and professional development.
40. Evaluation of the antimicrobial efficiency of natural extracts combined with irradiation treatment against foodborne pathogens
The aim of this project is to determine the antimicrobial activity of selected food ingredients in combination with non thermal treatments (X-ray, gamma irradiation) against foodborne pathogens (bacteria, yeasts and molds). The antimicrobial activity will be determined by the evaluation of Minimum Inhibitory Concentration (MIC) of the selected compounds. The checkerboard method will also be used to evaluate the synergic effects between antimicrobial agents. Radiosensitization curves (D10 values) will be established to characterize the combined treatments and to determine the radiosensitivity of pathogens. The effect of energy level (keV-MeV), dose (Gy), dose rate (Gy/min) of irradiation will be evaluated on the food decontamination efficiency (% of pathogen inhibition).
Objectives:
1) Determination of the antimicrobial properties of selected natural ingredients combined with non-thermal processing such as X-ray, gamma irradiation, and associated hurdle technology.
2) Identification of the ingredients that contribute to synergic antimicrobial effects, and determination of their antimicrobial capacity in food homogenates (in vitro-tests).
3) Determination of the combined effect of ingredients with X-ray and/or gamma irradiation in optimal conditions (parameters: energy level, dose rate, dose, ingredient concentration).
4) Determination of the combined treatments on the shelf-life and quality of food products (in situ tests).
5) Eventually: changes in gene expression (stress and virulence gene) may be studied to characterize the mechanism of radioresistance of targeted pathogens (bacteria, molds).
Methodology
- The MIC value of ingredients will be determined according to the serial microdilution method developed in our laboratories. Serial dilutions will be made in suitable culture media and dispensed into 96-well microplates. After inoculation with a pathogenic strain and incubation, the absorbance will be measured at 595 nm with a microplate reader.
- The synergy of ingredients will be determined based on a checkerboard procedure developed in our laboratories and following the same microdilution method.
Research area, student roles & skills
Research area: Professor Monique Lacroix, Ph.D.
My research works in food science and nanotechnologies promotes the development of agri-food industry through new processing technologies to ensure food safety and quality, including the development new, value-added products. The development and application of new, non-thermal technologies (X-ray, gamma irradiation, UV-C) or hurdle technologies (combinations of treatments with heat, bioactive packaging, modified atmosphere, ozone) reduces food losses while ensuring the preservation of nutritional value and safety of the product. New processes are monitored by various spheres of activity, such as food and polymer chemistry, nanostructures, physicochemical/rheological properties of advanced materials, microbiological/sensory analyses, and genomics.
Student roles: The student will participate in all steps of the methodology mentioned above, and will be mainly involved in microbiological analyses: - Preparation of pathogen strains and culture media. - Inoculation in sterile conditions (challenge tests). - Microplate readings (UV-Visible spectrophotometry). - Food processing by using non-thermal treatments (e.g. X-ray). - Microbiological, physicochemical and statistical analyses. - Interpretation of results, report writing, oral and written communication.

Essential: The student can work under a biological safety cabinet and has received WHMIS and Biosafety trainings.
Our research is at the crossroad between cell biology and population genetics. We are interested in this project in testing if we can predict how organisms can evolve drug resistance through (antifungals, antibiotics, and antifolates) the accumulation of mutations. We want to determine which are the most likely routes of resistance and by what type of mutations, and if those mutations lead to fitness trade-off. Our work has impacts on fundamental aspects of evolution as well as on public health and drug development strategies.
See our recent publications on the topic here:
https://www.science.org/doi/full/10.1126/sciadv.add9109
https://www.nature.com/articles/s41559-022-01846-4
Research area, student roles & skills
Research area: We study the evolution of genomes and of cellular systems in the context of long-term evolution, for instance in the context of gene duplication and the birth of genes, and in the context of short-term evolution such as during the evolution of drug resistance. We use high-throughput experimental evolution and genome editing as well as computational biology tools.
Student roles: The student will contribute to our research projects by performing wet lab experiments and/or computational analyses. He will be supervised by a graduate student or a postdoctoral fellow in the laboratory. He will have to communicate his work orally at group meetings and on paper in research articles.
Malaria transmission from humans to mosquitoes depends on the formation of gametocytes — sexual-stage parasites that are the only forms infectious to the Anopheles vector. P. falciparum commits only a small fraction of its asexual population to gametocytogenesis in each replication cycle, and the molecular cues that trigger this commitment remain incompletely understood. Extracellular vesicles (EVs) have emerged as compelling candidate signals: studies show that EVs from infected red blood cells can stimulate gametocyte conversion in recipient parasites, and that this effect is at least partially dependent on EV cargo. However, which specific molecular components carry this gametocytogenic signal is unknown.
Our laboratory is uniquely positioned to investigate this question. We have established comprehensive stage-specific EV isolation and characterization protocols, and our multi-omic datasets (proteomics, transcriptomics, lipidomics currently in completion) provide a rich resource for identifying candidate gametocytogenic signals. Our preliminary proteomic data show stage-specific differences in EV cargo that include proteins associated with epigenetic regulation and stress response — both implicated in commitment decisions. Ongoing work in the laboratory directly investigates the relationship between EV cargo and gametocytogenic signaling, and this Globalink student will contribute to and complement that work.
A second, complementary angle of this project concerns EV-mediated modulation of RBC invasion. Our proteomic analysis reveals that parasite EVs are enriched in host-derived glycan-bearing membrane proteins — including glycophorin A and band 3 — captured during schizont rupture. This raises the hypothesis that EVs interact with, and potentially modify, glycan receptor organization on the RBC surface to influence subsequent invasion. The student will perform quantitative invasion assays with EV-treated RBCs, and use fluorescence microscopy to examine whether EV binding alters surface glycan epitope distribution. Together, the two angles of this project address how P. falciparum EVs function as both within-population communication signals (gametocytogenesis) and host-interface modulators (invasion).
Research area, student roles & skills
Research area: Our laboratory studies extracellular vesicles (EVs) in Plasmodium falciparum malaria, focusing on their roles in parasite-to-parasite communication, host-cell invasion, and sexual stage commitment. P. falciparum must periodically convert from asexually replicating blood-stage parasites into gametocytes — the sexual forms transmissible to the mosquito vector. EVs released by infected red blood cells have been implicated in triggering this conversion, but the molecular signals they carry remain poorly characterized. In parallel, we investigate how parasite-derived EVs interact with red blood cell surface glycans to influence invasion efficiency, linking EV biology to host-receptor biology.
Student roles: The student will be supervised by a senior graduate student working on the gametocytogenesis project and directly mentored by Dr. Rohrbach. Full laboratory training will be provided upon arrival, beginning with safety orientation and P. falciparum culture. The student will first learn to maintain continuous asexual P. falciparum cultures (strain 3D7 and/or NF54, which is gametocyte-competent) using human RBCs from a licensed blood bank. The student will then learn to isolate stage-specific EVs from synchronized cultures using differential centrifugation and size-exclusion chromatography, and to characterize them by nanoparticle tracking analysis (Particle Metrix ZetaView). Mastery of these foundational skills underpins all downstream experiments. For the gametocytogenesis arm, the student will conduct EV transfer experiments: adding purified EV fractions from defined asexual stages to NF54 cultures and quantifying gametocyte conversion rates over 5–7 day timecourses using Giemsa-stained smears and flow cytometry. The student will compare the potency of EVs from different asexual stages (ring vs. trophozoite vs. schizont) to identify which populations carry the strongest gametocytogenic signal, and will contribute to candidate-signal experiments guided by our ongoing multi-omic analysis. For the invasion arm, the student will perform quantitative flow cytometry-based invasion assays comparing EV-treated versus control RBCs, and contribute to fluorescence microscopy experiments examining glycan epitope distribution on EV-treated RBC surfaces. The student will attend weekly lab meetings, maintain a detailed laboratory notebook, deliver a final oral presentation, and submit a written project report at the end of the internship.
Skills required: The student should have a background in cell biology, microbiology, or biochemistry. Interest in infectious disease, parasite biology, or cell signaling is a strong asset. Prior experience with cell culture, microscopy, or flow cytometry is welcome but not required — all techniques will be taught. The student should be organized, comfortable with quantitative data, and willing to work in a BSL-2 laboratory environment (full safety training provided on arrival). Students from life sciences, biomedical sciences, or biochemistry programs are encouraged to apply.
43. Feasibility of a Multiplexed Biosensor for Neonatal Sepsis Detection in Clinical Samples
Neonatal sepsis is a life-threatening systemic infection occurring within the first 28 days of life and remains one of the leading causes of neonatal mortality worldwide, particularly in low-resource settings. Timely diagnosis is critically challenging due to the non-specific clinical presentation in neonates, low blood volumes available for sampling, and the lengthy turnaround times of conventional blood cultures (24–72 hours). Elevated biomarkers such as C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6), and interleukin-8 (IL-8) are associated with early-onset sepsis, but rapid, sensitive, and low-volume detection platforms remain unavailable at the bedside.
This project will assess the feasibility of a multiplexed electrochemical biosensor for simultaneous detection of key neonatal sepsis biomarkers directly in clinical neonatal blood samples. The work will encompass biosensor development, optimization in complex biological matrices, and initial validation using clinical samples collected in partnership with the neonatal intensive care unit (NICU). This research directly addresses an urgent unmet clinical need and has a clear translational pathway toward point-of-care deployment.
Research area, student roles & skills
Research area: Every hour counts when a newborn develops sepsis yet current diagnostic methods take up to 72 hours. Our lab builds miniaturized biosensors that detect life-threatening infections in a single drop of blood within minutes, directly at the bedside. We combine cutting-edge electrochemistry, nanotechnology, and immunoassay engineering to create smart diagnostic devices that could one day replace slow, costly lab tests in neonatal intensive care units worldwide. If you are passionate about using chemistry and engineering to solve real clinical problems and save newborn lives, this project offers hands-on experience at the exciting frontier of point-of-care diagnostics and translational biomedical

44. From Waste to Value: A Comparative Biorefinery Approach for the Extraction of High-Value Compounds from Birch and Spruce Bark
Supervisor: Véronic Landry
University: Université Laval (Québec campus)
Location: Québec, Québec
Start date: 2027-05-10 (flexible)
Disciplines: Biochemistry, Chemistry, Engg-Chemical, Science and Technology
Bark accounts for 10 to 15% of the total biomass of the tree and is generated in large quantities as a residue from sawing and pulping operations in Quebec and Canada. Yet the majority of this biomass is currently landfilled or burned without prior extraction, representing a considerable loss of biochemical and economic value.
This project proposes a dual valorization strategy applied to two bark types with complementary chemical profiles: birch bark, rich in suberin (up to 40% of dry weight), betulin, betulinic acid and resinous extractives, and spruce bark, an important source of condensed tannins and polyphenolic compounds with documented applications in bio-based adhesives, coatings and antioxidant formulations.
The central question is whether high-value compounds can be selectively extracted from each bark type while preserving sufficient calorific value for viable energy recovery. Two complementary approaches are implemented. The sequential approach subjects bark samples to successive extractions targeting resins and terpenes, tannins and polyphenols, and suberin, with measurement of the residue's calorific value after each step by bomb calorimetry. The parallel approach applies independent protocols to separate batches, enabling direct comparison of extraction efficiency and residual energy content between protocols and between species.
Thermal characterization by TGA-FTIR links the chemical composition of extracts and residues to their energetic performance and combustion behavior. This comparative design, covering two species and two extraction strategies, is intended to generate knowledge directly transferable to biorefinery sequencing across the Quebec forest sector.
Research area, student roles & skills
Research area: My research focuses on the chemistry and performance of wood finishing products, bio-based adhesives and coatings, and wood modification and impregnation.

I also work on stimuli-responsive and smart coatings, as well as bio-based formulations for interior and exterior wood finishing applications.
Student roles: The student will carry out extractions of high-value compounds from birch and spruce bark, including suberin, betulin, tannins and polyphenols, following established sequential and parallel extraction protocols using solvents such as hexane, acetone and ethanol-water mixtures, as well as alkaline hydrolysis for suberin isolation. All experimental work will be conducted under the supervision of a research professional, ensuring proper training in laboratory techniques and safety procedures. The student will perform comprehensive chemical and thermal characterization of the extracts and residues using a range of analytical techniques, including FTIR spectroscopy, thermogravimetric analysis coupled with FTIR (TGA-FTIR), and bomb calorimetry for the evaluation of residual calorific value. The student will also contribute to chromatographic analyses (GC-MS, HPLC) for the identification and quantification of extracted compounds, as well as to the comparison of extraction efficiency between protocols and between species. Beyond experimental work, the student will be expected to actively participate in data analysis and interpretation. The student will present results at lab meetings, and will collaborate closely with the postdoctoral researcher, other graduate students and members of the research team. This position offers a valuable opportunity to develop expertise at the interface of forest biomass valorization, green chemistry and material characterization, within a dynamic and interdisciplinary research environment connected to the Quebec forest products industry.
Skills required: The ideal candidate holds a background in chemistry, wood science, materials science, or a related field. Experience in chemical characterization techniques such as FTIR, TGA, or chromatography (GC-MS, HPLC) is an asset. Familiarity with extraction protocols, bio-based materials, or wood finishing products is welcome but not required.

In addition to coding sequences, the genome carries regulatory motifs involved in gene expression and function. General components of genes such as promoter regions, enhancers, transcriptional start sites, etc. have been described from experimental observations, but we still lack a unifying definition of what a typical gene looks like. We have already trained a robust convolutional neural network that classifies human sequences as protein-coding genes or intergenic regions. Your objective will be to train and interpret machine learning models from which we can infer an unbiased definition of a gene beyond the human genome.

48. Genome editing using non-viral nanoparticle delivery
Supervisor: Shyh-Dar Li
University: University of British Columbia (Vancouver campus)
Gene editing provides an alternative treatment for diseases that cannot be cured by conventional therapies. Those challenging diseases include cancer, genetic disorders, and viral infection. The limiting step for gene editing is efficient delivery of genome editing components into the target cells. The delivery system needs to overcome various barriers and release the biological payloads in the target site. The major delivery barriers include rapid enzymatic degradation, renal elimination, efficient uptake by the target cells and release in the desirable subcellular compartment for optimal effect. The Li lab focuses on developing innovative nanoparticle delivery systems that provide stable and efficient encapsulation of gene editing components and target them to specific cells. Ultimately, these nanoparticles will be used to treat genetic disorders in both in vitro and in vivo models.

Research area: The overarching theme of my research program is to better understand the mechanisms underlying tissue injury and wound healing in aging-related, chronic inflammatory conditions. Through phenotypic and molecular characterizations using in vitro studies, in vivo models, and patient biospecimens, our goal is to identify therapeutic targets that could be modulated to improve disease severity and clinical symptoms in patients. In particular, our team is interested in a family of serine proteases known as granzymes (granule-secreted enzymes). Over the past 20+ years, our team has discovered a pathogenic role for granzymes in many age-related, chronic inflammatory conditions/diseases in diverse tissues.
Student roles: The student will be immersed in a wide range of translational research activities and will work with a Postdoctoral Fellow or Senior Graduate Student supervisor. Day to day tasks will include designing studies, running experiments, scientifically documenting methodology and results, analyzing and interpreting findings, discussing data with supervisors, organizing data into presentations, delivering presentations at lab meetings and local research meetings, writing and editing research manuscripts as well as assisting with other lab duties and studies.
Skills required: We are looking for a highly-motivated, committed student with a passion for biomedical research and discovery. A background related to immunology, molecular biology, biochemistry, biology, physiology and/or physiology is preferred while previous hands-on experience with techniques such as tissue culture, protein/protease work, immunohistochemistry/histology is an asset. This work term is suitable for a senior student who has previous laboratory experience and is comfortable working independently and on a team. The laboratory is a dynamic, fast-paced, collaborative environment. Excellent written and oral communication skills are essential.
Natural fibers, or biopolymers, are attracting a great deal of interest from the scientific community. They are abundant, renewable, biocompatible and biodegradable. In addition to their low production costs, their great diversity provides them remarkable physicochemical, mechanical and thermal properties, making them a serious alternative to their synthetic analogues. However, additional surface modification steps are often required to provide these fibers with the specific functionalities required for certain applications in fields, such as biomedicine, the environment and catalysis. Among these biopolymers, cellulose, lignin and pectin occupy a prominent position in terms of abundance, sources, diversity, properties and numerous applications. These natural fibers, especially cellulose either in its micro or nano forms, are the subject of sustained research work in my laboratory. The results obtained so far are promising and open up very exciting prospects.
The aim of this research project is to optimize the surface modification of these fibers by metallic nanoparticles to yield functional hybrid biomaterials which remain susceptible, where appropriate, to other post-functionalization procedures, for example, via the grafting of biomolecules of interest. The process that will be implemented embraces several of Green Chemistry Principles: water as the solvent, energy efficiency, use of renewable resources, and maximum yield, to name a few.
The physicochemical characterization of the newly obtained hybrid biomaterials will be carried out using several techniques, such as UV-Vis, XRD, TEM/SEM, FTIR, etc. The exploration of their biological properties will focus on antioxidant and antimicrobial activities while their catalytic properties will target the degradation of organic dyes. Depending on the results obtained and the progress of the work, the study of other properties with a view to other applications may be envisaged.
Research area, student roles & skills
Research area: My research interests focus on the synthesis of a wide range of functional inorganic nanoparticles based on Green Chemistry methods, their characterization using various physico-chemical techniques, the exploration of reaction mechanisms, and the study of their various physicochemical and biological properties for applications in several fields, including biomedicine, environment and catalysis. They also focus on modifying the surface of natural fibers, such as cellulose and pectin, with bio-molecules, polymers and/or inorganic nanoparticles, to obtain functional biohybrids with potential applications in several fields (biomedicine, environment, catalysis...).
Student roles: The trainee will work on the proposed topic under my close supervision in concert with other members of my team and will interact with the colleagues with whom I collaborate. The student will conduct bibliographic research on different methods used for the deposition of inorganic nanoparticles on natural fibers and will learn about the results already obtained by my other trainees. Following this, the student will be able to propose a detailed experimental work plan which we will further discuss in terms of strengths and weaknesses, feasibility and expected results. Then, the student will be trained to use various equipment and instruments necessary to carry out their project and will proceed with the implementation of this project, namely: (i) the production of nanocomposite biomaterials made of natural fibers decorated with metallic nanoparticles; (ii) characterization of their physicochemical properties; (iii) exploration of the mechanistic aspects leading to their formation; and (iii) evaluation of their biological and/or catalytic properties. In addition, the student will be responsible for processing and interpreting the obtained results. Their work will be crowned by the writing of a report showcasing the obtained results which are likely to give rise to a scientific article and/or to an oral presentation/poster at the end of their internship.
Skills required: The candidate must be motivated to quickly integrate into their new environment. To successfully complete their project, they must: demonstrate sufficient scientific culture in chemistry or related fields; have knowledge of nano-materials (an asset); master some characterization techniques (FTIR, XRD, TEM, etc.); possess work experience in the laboratory to read and implement experimental protocols, learn to use equipment and instruments, and become autonomous after a few weeks of internship and training; update their knowledge on the subject by carry out the adequate bibliographic research; and be able to process and interpret the results.
51. Harnessing light and carbon dioxide to make medical imaging drugs
Carbon-11 is among the most useful radioactive isotopes for medical imaging thanks to its short half-life, low energy positron emission, and convenient production using hospital-based cyclotrons. Most importantly, as carbon forms the backbone of most biomolecules and pharmaceuticals, carbon-11 can be seamlessly integrated into their chemical structures without altering their characteristics. Our lab develops innovative chemical methods to link carbon-11 and other isotopes into complex molecules for the purposes of discovering new medical imaging drugs and improving access to radiopharmaceuticals with better manufacturing.
To make effective use of short-lived isotopes, chemical methods must be efficient, selective, and compatible with complex molecules for late-stage labeling of imaging agents. For carbon-11, it is advantageous to elicit the desired reactivity from carbon dioxide, which is produced directly on medical cyclotrons. We have developed radiochemical methods with carbon-11 CO2 that are effective due to judicious use of novel chemical precursors and catalysts based on transition metals, simple organic molecules, and light-activated molecules. These methods furnish unique access to in-demand radiopharmaceuticals by robust methods that can be used for new tracer discovery.
Our current directions for carbon-11 radiochemistry include photocatalysis, flow chemistry, selective reducing agents, and catalysts that can recognize and activate CO2 towards complex precursors. While the specific experiments to be planned for this Mitacs GRI project will not be defined until close to the internship, we are currently exploring a set of photocatalytic reactions to directly incorporate carbon-11 CO2 into molecules containing ketones, aldehydes, and imines and targeting related biomolecules, such as hydroxyacids and amino acids. We initially evaluate reactivity under non-radioactive conditions, prior to translating methods for use with carbon-11 using remote-controlled apparatus in a specialized laboratory. We use purification and characterization techniques specific for radiochemistry to evaluate the suitability of a method for medical imaging applications.
Research area, student roles & skills
Research area: Molecular imaging allows for non-invasive visualization and quantification of biochemical and pharmacological processes in living systems and has important applications for clinical diagnosis and disease research. An imaging drug containing a radioactive atom is administered to a patient and then its distribution in the body is tracked using a specialized camera. Our research program develops imaging drugs to reveal valuable information in cardiovascular disease, inflammatory conditions, neuronal diseases, and cancer. This includes methods to incorporate radioactive atoms into molecules, new molecule discovery, and evaluation in disease models.
Student roles: Students will be responsible for maintaining practices and protocols related to safety and efficient operations of the laboratory. This includes completing mandatory training modules, practicing good laboratory techniques, and communicating with coworkers and the principal investigator. Students will receive hands-on training in specialized techniques and be responsible for acquiring skills to complete the needed experiments. Students will maintain a detailed laboratory notebook and prepare regular reports to facilitate discussions, as well as present their work to the research team. Students are expected to become knowledgeable in the subject matter by reading relevant literature, accessing literature databases, and participating in group discussions. Students will assist senior personnel in conducting experiments towards the aims of the research project. This includes working on a team and being individually responsible for technical tasks. Students will train in specialized techniques and instrumentation and be responsible for operating these independently, including data acquisition and analysis. Opportunities will be provided to take on greater responsibility commensurate with demonstrated skills.
Skills required: Students should possess a strong background in university-level natural science courses as demonstrated by very good to excellent grades in intermediate chemistry and biochemistry, including laboratory courses. The students should have an interest in pursuing laboratory natural science or biomedical research during their undergraduate studies and during graduate studies. Previous research laboratory experience is desirable but is not required. We seek students with strong written and verbal communication skills and enthusiasm for working independently and as part of a team. Our research group promotes principles of equity, diversity, and inclusion in recruitment.
52. How do peroxisome-mitochondria contact sites control mitochondrial function
Cells are organised into specialised compartments called organelles, which must communicate to keep the cell healthy. One important form of communication occurs at membrane contact sites, where two organelles touch without fusing and exchange material and signals. Peroxisome-mitochondria contact sites (“PerMit”) are zones where these two metabolic organelles physically connect to exchange metabolites and to buffer reactive oxygen species. Recent work has begun to identify the proteins that hold these contacts together. Still, a basic question remains unanswered: does the number of contacts actually change how much energy mitochondria produce?
The intern will help answer this using a tool developed in our laboratory: a chemically inducible system that stabilises PerMit on demand and can also be switched off again. Working with cultured human cells, the intern will compare cells in which contacts have been induced (“ON”) with cells in which they have been dissolved (“OFF”), and measure the effect on mitochondrial respiration using the Seahorse XF Pro analyser. In parallel, the intern will use fluorescence microscopy to image and count the contacts themselves, so that respiration can be related directly to contact-site abundance. Appropriate controls and repeat experiments will ensure the results are robust.
The 12-week objective is a clean, reproducible dataset linking contact-site abundance to mitochondrial oxygen consumption: a focused, self-contained contribution to a larger research program on organelle cooperation and metabolism. Because both organelles are disrupted in rare metabolic and neurological diseases, understanding their cooperation also has long-term relevance to human health. The project is well-suited to a motivated undergraduate: the core techniques can be learned within the first few weeks, the daily work is hands-on, and the experiments produce clear, quantitative results that the intern will analyse and present to the group.
Research area, student roles & skills
Research area: Our laboratory studies how cells coordinate their organelles, focusing on the functional partnership between mitochondria and peroxisomes, organelles that cooperate in fatty-acid metabolism and in controlling reactive oxygen species. We combine mammalian cell biology, live-cell fluorescence microscopy, inducible protein-tethering tools, and real-time respirometry to understand how physical contacts between organelles form, how they are regulated, and how they shape metabolic output. The work sits at the interface of cell biology, biochemistry, and metabolism, and connects to human health through rare mitochondrial and peroxisomal diseases. Our newly established lab features a cellular metabolism platform.
Student roles: Under the day-to-day mentorship of the supervisor and a senior laboratory member, the intern will be a full participant in the project rather than an observer. After an initial onboarding and safety period, the intern will progressively take ownership of a defined set of experiments. Day-to-day responsibilities will include: maintaining human cell cultures and preparing experimental samples; carrying out the inducible contact-site experiments, including the induced (“ON”) and dissolved (“OFF”) conditions together with their controls; running mitochondrial respirometry assays on the Seahorse XF Pro; acquiring fluorescence-microscopy images of organelle contacts; and quantifying and analysing the resulting data using standard imaging and statistical tools. The intern will keep a detailed, well-organised laboratory notebook and will be responsible for the integrity and traceability of their data. Throughout the placement, the intern will meet weekly with the supervisor, present progress at laboratory meetings, and take part in the lab’s journal club, developing the ability to read primary literature critically and to communicate scientific results clearly. The intern will also complete the institutional safety and biosafety training required to work in the laboratory. We expect the intern to work carefully and independently while asking questions freely, and to contribute to the collaborative, supportive culture of the group. By the end of the 12 weeks, the intern will have learned a coherent set of cell-biology and metabolism techniques, generated and analysed an original dataset linking organelle contacts to mitochondrial function, and presented their findings to the laboratory. Where the results support it, the intern’s contribution may feed into a future publication.
Skills required: We seek a student in cell or molecular biology, biochemistry, biotechnology, or a related life science, with: • coursework in cell biology and biochemistry (molecular biology an asset); • some hands-on lab experience, ideally including sterile technique or cell culture (full training provided); • basic data-analysis skills (spreadsheets, graphing; ImageJ/Fiji or GraphPad a bonus); • careful, organised work habits and reliable record-keeping; • a strong working knowledge of English (French welcome, not required); • curiosity, initiative, and the ability to work independently and in a team. Prior microscopy experience is an advantage.
53. How the nuclear receptor LRH-1 rewires energy metabolism in triple-negative breast cancer
Cancer cells rewire their metabolism to fuel rapid growth and resist treatment, and triple-negative breast cancer (TNBC) — the most aggressive breast cancer subtype, with no targeted therapy — depends heavily on this metabolic flexibility. The nuclear receptor LRH-1 (NR5A2) is a master regulator of lipid, cholesterol, and energy metabolism, and its activity is linked to TNBC progression. Strikingly, LRH-1 also appears inside mitochondria in TNBC cells, hinting at a direct line of control between the nucleus and the cell’s powerhouses.
Potent, selective small molecules that activate LRH-1 now exist, giving a precise way to switch the receptor on. What remains unclear is exactly how changing LRH-1 activity reshapes mitochondrial energy production in cancer cells. The intern will address this directly. Working with cultured TNBC cells, the intern will treat cells with increasing doses of an LRH-1 modulator, and in parallel silence LRH-1, then measure the metabolic consequences on respiration, ATP production, and the cell’s preference for fuels such as fatty acids, glucose, and glutamine, with results normalised to cell number.
The 12-week objective is a clean, reproducible dataset linking LRH-1 activity to the rewiring of cancer-cell energy metabolism, a focused contribution that feeds a larger program using tumour spheroids and patient-derived models. The project suits a motivated undergraduate: the core techniques are learnable within the first weeks, and the experiments produce clear, quantitative results that the intern will analyse and present.
Research area, student roles & skills
Research area: Our laboratory studies how mitochondria and cellular metabolism are reprogrammed in disease. One axis focuses on the nuclear receptor LRH-1 (NR5A2) in triple-negative breast cancer (TNBC), an aggressive subtype that still lacks targeted therapies. LRH-1 controls lipid and energy metabolism and, unexpectedly, also localizes to mitochondria in TNBC cells, suggesting a nuclear–mitochondrial regulatory axis. Using potent LRH-1 modulators and gene silencing, we ask how this receptor rewires cancer-cell energy metabolism. We combine cell biology, pharmacology, and real-time respirometry, supported by a cellular-metabolism platform.
Student roles: Under the day-to-day mentorship of the supervisor and a senior laboratory member, the intern will be a full participant in the project rather than an observer. After an initial onboarding and safety period, the intern will progressively take ownership of a defined set of experiments. Day-to-day, the intern will: • maintain triple-negative breast cancer cell cultures and treat them with a dose series of an LRH-1 modulator, alongside LRH-1 silencing and appropriate controls; • run mitochondrial respirometry assays on the Seahorse XF Pro; • measure cell number for normalisation; • and confirm LRH-1 silencing by standard molecular methods. The intern will analyse the resulting data and keep a detailed, well-organised laboratory notebook, ensuring the integrity and traceability of their data. Throughout the placement, the intern will meet weekly with the supervisor, present progress at laboratory meetings, and take part in the lab’s journal club, developing the ability to read primary literature critically and to communicate results clearly.

No prior experience with respirometry or cancer-cell models is needed.
54. Identification of novel ectonucleotidase inhibitors
Nucleoside triphosphate diphosphohydrolases (NTPDases) and other ectonucleotidases are enzymes that hydrolyze nucleotides at the cell surface. These nucleotides affect various biological functions via the activation of nucleotide (P2) receptors. To state a few examples, we observed that inflammatory processes, cancer, thrombosis and bone formation (in bone diseases) are all affected by the activity of these enzymes. In collaboration with chemists specialized in nucleotide research from Israel, Pakistan, USA and Germany we have developed several inhibitors of these enzymes. These inhibitors are synthetized with the medium term goal to regulate the above biological functions (each being specific for a single ectonucleotidase).
Before testing these novel molecules on ectonucleotidase activity we will express the recombinant form of each of these enzymes in a mammalian expression system (such as COS-7) and partially purify these enzymes. The expression level and activity of these prepared proteins will be confirmed and evaluated by Western blot and activity assays. The novel potential inhibitors will be tested for potency and specificity on each of these ectonucleotidases for the identification of both general inhibitors and specific inhibitors. It is also possible that some of the best inhibitors will be tested in the relevant biological assays with mice, and/or human or mice primary cells.
This project is designed for both: develop tools for basic research and develop/test molecules for a potential clinical application.

55. Identification of the Src-dependent spindle proteins
Supervisor: Sabine Elowe
University: Université Laval (Québec campus)
Location: Québec, Québec
Start date: 2027-06-01 (flexible)
Disciplines: Biochemistry, Biological Sciences, Biologie, Biology, Medical Sciences, Molecular Biology
While we know a lot about certain types of protein modifications during cell division, the role of tyrosine phosphorylation (a specific chemical change to proteins) during mitosis is still not well understood. So far, research has mainly focused on a group of enzymes called Src family kinases, which seem to affect how the spindle—the structure that separates chromosomes—is positioned and how the cell eventually splits in two. These enzymes might also play a role in meiosis (the cell division that produces eggs and sperm), but that area is not well studied yet.
Our lab has recently found that tyrosine phosphorylation happens quite a bit during mitosis, especially at the spindle poles and the cell cortex (outer region of the cell). Using a technique called immunofluorescence, we’ve seen that these phosphorylated proteins often show up in the same places as gamma-tubulin (a marker of spindle poles) and alpha-tubulin (a component of microtubules).
We’ve now identified several proteins that are phosphorylated on tyrosine specifically during mitosis. For this project, you will focus on one of these proteins and investigate how this phosphorylation affects its function during cell division. This will involve hands-on lab work and may include molecular biology, cell imaging, and protein analysis techniques.
Research area, student roles & skills
Research area: When a normal cell divides, it should do so equally. That means that each of the resulting 'daughter' cells should receive equal amounts of chromosomes from the original 'mother' cell. If this does not happen, the resulting daughter cells will have unequal number of chromosomes, a pathogenic state known as aneuploidy. Aneuploidy is therefore caused by incorrect cell division. It is the main cause of miscarriage with approximately 30% of miscarriages being aneuploid. Also, aneuploidy can cause mental and physical abnormalities in newborns and contributes to cancer in adults. Our overarching aim is to identify mechanisms that protect against aneuploidy.
Student roles: Interesting hits that are relevant to mitosis identified from a mass psectrometry screen we performed will verified and further explored in cell culture experiments. In this context, the intern will be introduced to methods in cell culture, high resolution microscopy including spinning disc confocal microscopy. In addition, the candidate will be introduced to methods in molecular biology. Importantly, the student will also gain theoretical knowledge in field of cell cycle biology. In addition to the scientific training, there will the opportunity to gain training and experience in more generally applicable skills including critical thinking and problem solving, as well as presentation skills. Overall, the intern will have an excellent idea by the end of the 12 weeks of some of the rewards and challenges of graduate studies.
Skills required: - Good communication and critical thinking skills. - scientific rigour and ethical conduct. - Enthusiasm, ambition and interest in the project. - Ability to work in a team-environment. - Previous laboratory experience is an asset but not necessary.
56. Identifying Cellular Factors that Disassemble Natural Amyloid Aggregates
Supervisor: Timothy Audas
University: Simon Fraser University (Burnaby campus)
As the formation of natural amyloids is fully reversible, understanding how cells breakdown these protein aggregates should provide important insight into the etiology and treatment of common neurodegenerative diseases. Our previous work has shown that Hsp70 is implicated in this disassembly process, but it is well established that this cellular chaperone is unable to re-fold proteins on its own. The DNAJ family, which contains more that 40 co-chaperones, regulates binding and function of Hsp70. Thus, we hypothesize that one or more DNAJ proteins are required for the efficient disassembly of these amyloid aggregates.
The goal of this research project is to screen DNAJ proteins, and assess whether they regulate amyloid disaggregation. First, the student will use RT-PCR to isolate and amplify a panel of DNAJ open reading frames, which will be cloned into GFP-tagged expression vectors. Second, the plasmids will be transfected in to cultured mammalian cell lines. Co-localization of each DNAJ protein with physiological amyloids will then be assessed by fluorescence microscopy. Finally, amyloid disassembly kinetics will be measured in the presence and absence of the candidate DNAJ proteins. Overall, this data will help generate a “parts list” of cellular machinery that has the capacity to disaggregate amyloid structures, and may ultimately point to candidate genes that could be dysregulated in patients suffering from amyloid-based neurological disorders.
Research area, student roles & skills
Research area: Our lab studies a natural and reversible protein aggregation pathway, which induces a dormant state to protect cells from harsh environmental conditions. In response to common stressors (i.e., heat shock and extracellular acidosis), mammalian cells sequester, immobilize and inactivate a large family of proteins within a subnuclear structure that possesses the same biophysical properties that are associated with the amyloid plaques seen in Alzheimer’s, Parkinson’s and prion-based diseases. Our work uses common cell biology and biochemistry techniques to uncover the molecular mechanisms underlying this physiological process.
Student roles: The student will learn basic molecular cloning techniques to isolate (PCR and gel electrophoresis), insert (restriction enzyme digestion and ligation) and purify (bacterial transformation and plasmid mini prep) the open reading frames of several cellular co-chaperones. These plasmids will then be sequenced, and the student will validate that the correct genes have been cloned.
Concurrently, the student will gain proficiency with basic tissue culture techniques. This includes the maintenance and manipulation of cultured mammalian cells. Once the cloning of the constructs has been completed (above), the plasmids will be transfected into the cell line. Fluorescence microscopy will then be used assess co-localization of the GFP-tagged DNAJ protein with the amyloid aggregates (detected using the amyloidophilic dye Congo red). Finally, candidate genes will be transfected and a time-course analysis will be performed to assess the rate of amyloid disassembly, in the presence or absence of the putative hit proteins.
All of the above experiments will be performed by the student, under the supervision of a senior lab member and the lab principal investigator.
Skills required: Interested students should have a background knowledge in molecular and cellular biology, with basic experience using common lab techniques (molecular cloning, gel electrophoresis, bacterial transformation). Some experience maintaining, transfecting and staining cultured mammalian cells would be highly beneficial.
57. Interstitial Needle Microendoscopy for Cancer Diagnostics
Supervisor: Alexandre Douplik

The project is devoted to the development of a microendoscope, which outer diameter is 195 microns, the inner diameter is 100 microns, and the length is 45 mm. This outer diameter resembles an acupuncture needle, but our needles are hollow and can deliver an endoscope. The main advantage of our scope - it can take small biopsies under imaging and spectroscopy control practically painlessly and causing no bleeding. The tissue destruction is minimal, and healing is fast. It allows performing biopsies and collecting diagnostic data not only in hospitals under anesthesia but also in small clinics and to apply biopsy easier, obtaining considerably more data per patient. Such an endoscope is a game changer for patient care, opening a more robust diagnostics perspective. Optical schematics and fluorescence imaging of normal and cancer in the breast can be seen in the pictures. This collaboration project is with University Health Network, Mount Sinai Hospital and Ontario Cancer Centre.

Autophagy is a multi-step degradation process that involves the sequestrating of cytoplasmic material into a transport vesicle called the autophagosome and the subsequent fusion of this autophagosome to the lysosome where the contents would be degraded by digestive enzymes inside this cellular "incinerator". The different steps of autophagy are mediated by a specialized suite of autophagy regulatory proteins and protein complexes. The proposed research project focuses on a human autophagy factor known as EPG5. EPG5 has been proposed to mediate the specific fusion between the autophagosome and the lysosome but the mechanism of action of EPG5 is not fully understood. Clinical genetics studies revealed that mutations to the gene encoding EPG5 cause a severe multi-system disorder known as Vici syndrome. Although many of these mutations have now been mapped, how these genetic alterations affect the function of EPG5 is unknown. The Yip laboratory recently developed a high-yield method to isolate pure EPG5 and this has enabled more comprehensive biochemical and molecular characterization of this very large-sized (~290kDa) protein. The proposed project will harness this powerful experimental platform and will specifically focus on examining the effects of various Vici syndrome disease mutations on the biochemical property and function of EPG5 using protein biochemistry, biophysical, and cell biology approaches.
Research area, student roles & skills
Research area: The majority of neurodegenerative diseases are strongly linked to the buildup of damaging protein masses in brain cells. One emerging therapeutic strategy is to activate brain cell’s
internal machinery to remove these toxic protein masses. Autophagy is an evolutionarily conserved pathway used by all cells in our bodies to target large objects such as protein
aggregates and organelles to a specialized compartment called the lysosome, where these objects will be degraded and their constituents recycled for other processes. Research in
the Yip laboratory is aimed at obtaining a comprehensive understanding of the molecular mechanisms of the human autophagy pathway.
Student roles: The Mitacs student will learn how to generate insect cell expression vectors of EPG5 encoding different Vici syndrome disease mutations by a site-directed mutagenesis approach or conventional PCR-based cloning. Once these vectors are generated, the student will assist a senior graduate student in the lab to optimize expression conditions and purification procedures for these mutant EPG5 proteins. The student will also gain exposure to other methods for characterizing the EPG5 mutants, including but not limited to GST pulldown protein-protein interaction assays, negative stain single-particle electron microscopy, and thermal melting assays. The Mitacs student will participate directly in this research project under the supervision of a postdoctoral fellow in the Yip laboratory. He or she will be involved in designing the experiments and carrying them out independently and/or under supervision. Our laboratory is fully equipped to carry out all the proposed experiments, and upon receiving proper training, the student will have access to all instruments. He or she will also have access to the shared resources within the UBC Department of Biochemistry and Molecular Biology, and the Life Science Institute, which include, but are not limited to, a transmission electron microscope, ultracentrifuges, and a film developer. Through this project, the student will acquire hands-on skills in key biochemical and molecular biology techniques and will also gain the opportunity to develop their critical thinking and problem-solving skills. Lastly, the student will have a valuable opportunity to develop his or her communication skills through presenting at bi-weekly laboratory meetings and preparing weekly progress reports.
Skills required: The candidate must be enrolled in a Bachelor of Science program in biochemistry, and other related life sciences or biological sciences disciplines with solid academic standings. Strong communication and organization skills, eagerness to learn new experimental techniques, and attention to detail are also required. The ideal candidate would have strong interests in pursuing a research career and have plans to pursue graduate studies in the future.

Cancer treatment puts an enormous burden on patients, their families and the health care system. This burden is heightened by complications that limit the success of current therapies. Thus, novel strategies are mandatory to provide treatment that is efficient, safe and beneficial to many patients.
Functionalized nanoparticles provide unique tools to interfere with tumor growth and kill cancer cells. To use nanoparticles successfully for medical applications, it is mandatory to understand how they interact with cells.
This project is dedicated to the development of new nanoparticles that eliminate cancer cells. Together with our collaborators, we generate nanoparticles with exceptional properties. These properties will eradicate cancer with extraordinary efficiency.
The proposed research will design and produce new nanoparticles. For future therapies, it is critical to characterize the nano-bio interface and optimize the nanoparticles for cancer cell killing.
To achieve this, we will address the following fundamental questions:
(1) What are the optimal nanoparticle properties that ensure the effective killing of cancer cells?
(2) What is the impact of these nanoparticles on normal cells?
(3) How do the nanoparticles enter tumor cells?
(4) How do the nanoparticles kill tumor cells? Specifically, which cellular organelles are damaged by the nanoparticles?
At present, cancer therapy faces overarching challenges: (i) Effective elimination of cancer cells, (ii) drug resistance, and (iii) the toxicity of treatment. To overcome these challenges, our research focuses on new technologies that are based on nanoparticles. To kill cancer cells, we will apply an innovative multidisciplinary approach and use high-tech instrumentation.
Given the large number of cancer patients and the difficulties that continue to limit treatment success, the completion of our project will be of high benefit to society. It will be relevant to the health of many patients worldwide.
Research area, student roles & skills

61. Machine learning for functional genomics and protein engineering applications
Such tools can be useful for the assignment of improved functions for orphan genes and sequences for orphan enzymes and for investigating enzyme promiscuity. Hence, there is the potential for the use of new protein language modeling representations using embeddings from natural language. Such improved protein language modeling methods can be valuable for multiple applications including optimizing protein solubility, stability, along with other functional properties of the enzymes such as catalytic activity and affinity. Finally, such protein language modeling methods will be valuable to engineer novel enzymes by combining it with existing experimental techniques such as directed evolution.
Research area, student roles & skills
Research area: Recent advances in machine learning has led to tools such as the AlphaFold from Google that enables the prediction of 3D structure from sequence. AlphaFold is a deep learning method based on neural networks that predicts high accuracy structures without requiring any templates. The success of AlphaFold motivates the development of similar techniques for other methods that currently rely exclusively on sequence information. For example, the development of genome-scale metabolic network reconstructions relies on the use of bioinformatic tools such as sequence alignment. Recently, our group demonstrated that augmenting sequence information with other features lead to improved metabolic network models.
Student roles: The student will develop new machine learning workflows, will prepare new training sets for protein sequences, train the new datasets on new workflows. The student will also identify deficiencies in the data sets that prevent training, evaluate the importance of specific features for protein modeling. In addition, the student will reproduce existing algorithms in the literature to establish a baseline against which the newly developed algorithms can be compared. The student will also download information periodically from on-line genomics and metagenomics databases not limited to UniProt, Swiss Prot and JGI and use these sequences for training not only literature methods but also newly developed algorithms. Student will develop metrics that measure the successful function prediction in the case of functional genomics and successful prediction of activity or promiscuity in the case of protein engineering and identify new experimental designs that can enable improved prediction and models. Finally the student will also closely interact with experimental biochemists to generate targeted data that can enable the improved performance of these methods. Student will also write a report documenting the research and contribute to a research article summarizing the results of the research. The student will also present their research at weekly group meetings and at local , national and international conferences and interact with collaborators from other Universities.
Skills required: The ideal will student will have strong background in computational biology, biochemistry and machine learning.

The student must be willing to learning techniques and work with senior researchers in order to execute new ideas and algorithms into code and test them out. Finally, the student should be comfortable programming in Python and familiarity with Pytorch and developing code for GPUs.
62. Manipulating premature cell aging to improve cancer therapy
Although we know that therapy-induced senescence (TIS) and other cell fate decisions like apoptosis (cell death) must occur during cancer treatment, whether they differentially alter the biology of damaged human tissues (and tumors), or impact clinical treatment outcomes for patients remain unknown. To explore this question, we use ovarian and prostate cancer biobank-derived patient tissues to probe the functional and predictive value of senescence-associated human cancer biomarkers. Primary cell cultures directly derived from tumor tissues are exposed to cancer therapy ex vivo and evaluated for their senescence responses. Similarly, biopsies collected from patient tissues at critical moments during therapy are organized into tissue microarrays and quantitatively probed for senescence-associated biomarkers, which are then correlated to clinical patients outcome. Our preliminary results suggests that a state of "senesence competence" is present in a subset of human tumors that retain a capacity to undergo TIS in response to treatment. The proposed project will continue to test the molecular signalling pathways regulating senescence competence in human cancer and will attempt to manipulate these pathways to favor beneficial clinical outcomes for patients (enhance current therapies).
Research area, student roles & skills
Research area: Cellular senescence is an anticancer program linking cellular stress responses to tissue remodeling. The impact of senescence on tissue homeostasis during development, tissue repair, and aging, is due to context-dependent beneficial and detrimental effects accompanying persistent senescent cells. This explains why senescent cells are suspected of playing a role when triggered during cancer treatments like radiation or chemotherapy.
Student roles: The student will be paired and directly supervised with a graduate student from my laboratory. The student will assist and perform experiments, analyze data, and realize figures to present the data that he has obtained. It is expected that the student will present experimental approaches, results obtained and data analysis during lab-meetings with the rest of the research group using multimedia support (oral presentation + diaporama).
Skills required: Theoretical and laboratory background in biology and cell biology is essential. Useful/complimentary knowledge: Bioinformatics, molecular biology, immunology, biochemistry, medicine, oncology.
63. Maskwio'mi: Biomedical Studies of a Re-Discovered Mi'kmaq Traditional Skin Remedy from Birch Bark
Supervisor: Matthias Bierenstiel
University: Cape Breton University (Sydney campus)
Location: Sydney, Nova Scotia
Start date: 2027-05-03 (flexible)
Disciplines: Biochemistry, Biological Sciences, Botany, Chemistry, Medical Sciences, Microbiology, Native Studies, Pharmacology, Pharmacy, Science and Technology, Veterinary Science and Medicine, Biology, Engg-Biomedical, Health Studies, Molecular Biology
The proposed Globalink project is a continuation of previous successful Globalink project involves the study of medicinal properties of birch bark extracts. Preliminary results show that the extract of birch (betula papyrifera) made in a fire pit method by the Mi'kmaq people contains more than 200 organic compounds. The student project involves the determination of medicinal properties, such as antibiotic properties, of this extract as a whole and of fractionations thereof. Bierenstiel developed new technology using electricity to substitute the conditions in a fire pit. This allows a better control of the extract conditions. Preliminary results show that this new technology allows faster reaction time and more product yield.
The student will be trained using the new extractor technology to safely produce the extract from birch bark in the laboratory. During this process, the different extracts are fractionated as a function of time and extraction conditions (as well as compared to extract from the fire pit method) and then studied using newly built microbiology lab. The student will be trained to independently setup antibiotic and MIC (minimum inhibitory concentration) experiments. The student’s role is to fully assist in the research data gathering of maskwio'mi for chemical analysis (NMR, FTIR, FT-Raman, UV-vis, UPLC-QToF-MSMS, GC-MSMS) and provide essential data for scientific publications.
The project is now further expanded to include biomedical studies such as antibiotic and anti-inflammatory experiences in our mircobiology laboratory.
Research area, student roles & skills
Research area: Indigenous medicine knowledge is rich but at risk of being forgotten as elders pass away. The Mi’kmaq skin remedy of maskwio'mi (maskwi = birch bark; o'mi = oil) is an extract from birch bark, traditionally made in a fire pit, with excellent medicinal properties for eczema, psoriasis and other skin conditions. PI’s Bierenstiel (Chemistry) and Young (Mi'kmaq Studies) are working with Mi’kmaq community of Membertou First Nation of Sydney, Nova Scotia with a 2-eyed seeing methodology to study maskwiomin with the goal of identifying what pharmaceutically active compounds are in the extract and what properties do these compounds have.
Student roles: The student has a central role in this Globalink project. The maskwio'mi project is still in the early exploratory stages where we probe the breadth of medicinal properties of that bark extract as well as trying to understand this complex mixture of organic compounds. We have preliminary results that maskwiomin is a broadspectrum antibiotic including being effective against antibiotic resistant bacteria strains such as MRSA. One project is now the reproduction of these experiments (in triplicate) and expansion to other bacteria strains than the so far six tested. This requires repetition of experiments - which is excellent for novice student researchers as one or two learned techniques are applied to other bacteria strains. In addition, another project involves testing for antimicrobial activities against fungi (yeasts and molds) which has not been conducted, yet.
On the chemistry side, we have shown reproducibility of the extract using the new extractor technology. The next steps are to narrow the search for compounds in this highly complex matrix as we have shown that it contains over 200 compounds. The student will be trained using UPLC- or GC-MSMS instrumentation to analyze the extract contents at first through comparison with MS libraries and then using fractionation techniques to narrow down the compound searches. With the biomedical studies, the student will conduct zone of inhibition antibiotic studies as well as MIC determinations. Further experiments will venture into inflammatory studies.
The microbiology/medicinal property study and the chemical analysis study are coupled together and new results will likely influence each other. Pending on study background of the participating student, the project will tip to on of these sub-projects.
The student will be working in a team of several researchers and a postdoctoral researcher will closely assist the student so that the experiments are done properly and safely.
Skills required: The Globalink project can be adjusted to the skill level of the participating student. Ideally, a student with a study background of biochemistry, medicinal chemistry, microbiology, pharmacology, or related field is preferred to ensure high level of experiential learning for the student. The project is very interdisciplinary and we welcome different study disciplines. In the past, second year students have participated with a focus on hands-on, lab bench experiments, whereas upper level students could utilize their discipline-specific knowledge on in-depth experimental data analysis. One important factor is excitement for research by the student with an inquisitive mindset.
64. Measuring exosomal proteins for early cancer diagnosis using a novel nano-sensor
Early diagnosis of cancer can significantly improve the survival rate of patients. For example, when diagnosed early, the five-year survival rate of ovarian cancer patients was 93%, which dropped to 31% when the cancer was found at a late stage. Conventional diagnostic imaging tests suffer from insensitivity and inaccuracy, often requiring a surgery to retrieve sample tissues to confirm the disease. In comparison, exosome is a type of emerging biomarker that can detect cancer early via non-invasive blood tests. Exosomes are nanoscale vesicles ranging from 30-150 nm in size, secreted from all cells into the body circulation. The biomolecules (e.g., proteins, nucleic acids, lipids) carried by exosomes are very similar to their cells of origin including those in cancer cells, and thus can be detected to report the presence of cancer. The relatively high concentration of exosomes in the blood provides them with the capacity for early cancer diagnosis.
In this project, we will develop an assay for highly sensitive and accurate measurement of cancer-related exosome proteins based on a nano-sensor established in Dr. Li’s lab. Exosomes will be purified from blood plasma or serum samples using size exclusion chromatography. The concentration and size distribution of the purified exosomes will be characterized with dynamic light scattering and electron microscopy techniques. Next, various strategies to quantify exosome protein markers using the nano-sensor will be investigated for both exosome membrane proteins and intra-vesicular proteins. The assay sensitivity, accuracy, and reproducibility will be evaluated with biostatistics tools. Blood samples from ovarian and bone cancer patients will be tested to demonstrate the assay performance. This project will pave the way for blood-test-based non-invasive diagnosis of cancer at a very early stage, offering a helping hand to tens of millions of cancer patients in the world.
Research area, student roles & skills
Research area: Dr. Huiyan Li directs the BioMed Innovation Lab at the University of Guelph, Canada. Our multidisciplinary research focuses on developing innovative micro-and nano-biosensors, with an emphasis on biomarker detection for early cancer diagnosis. We have developed a variety of sensors for highly sensitive and multiplexed protein detection by integrating biosensing, micro/nanotechnologies, bio-optics, and biomedicine. We have applied these technologies for the discovery of protein biomarkers in blood samples, shining a light on early non-invasive cancer diagnosis. Collectively, these efforts will eventually contribute to personalized cancer management, improving patient outcomes.
Student roles: The students will work on the project with the mentorship of Dr. Li and graduate students in the lab. One student will work on the assay development for blood plasma samples, and the other for blood serum samples. They will learn nanotechnology and fabricate the nano-sensor for highly sensitive protein detection. For sample preparation, the students will perform size exclusion chromatography to isolate exosomes from blood plasma or serum samples. They will then learn to characterize the exosomes using advanced microscopy technologies available on campus. The students will learn to conduct immunoassays using the nano-sensor and investigate different assay procedures to achieve optimal assay performance. They will learn to use biostatistics software to compute key assay parameters, such as limit of detection, repeatability, and dynamic range. In the end, the students will conduct assays using the developed procedure to measure exosome protein markers in real cancer samples.
In terms of communication and leaderships, the students will work closely with Dr. Li’s team members and our collaborators at the University of Guelph, including cancer clinicians and those from the Department of Chemistry. The students will be offered the opportunity to become the contact persons for these collaborations and participate in regular project meetings to report the research progress and roadblocks. They will also polish their oral and written communication skills by making presentations to the whole research group and writing progress reports and potential publications.
By completing the project, the students will gain multidisciplinary knowledge and learn the state-of-the-art technologies in nanotechnology, purification techniques, immunoassays, exosome research, and cancer diagnosis. They will also improve their communication skills and leadership in an open, dynamic, and highly collaborative research environment.
Skills required: Students with a general academic background in biochemistry, biological sciences, biological/biomedical engineering, medical sciences, or chemistry are welcome to apply. Qualified students are expected to have the basic knowledge to understand the motivation of this work, and have the ability and commitment to learn the hands-on operation of the nano-sensor for protein detection, including the chromatography for sample purification, nano-fabrication, immunoassay, and microscopy techniques. The students are also expected to be able to communicate effectively in a collaborative team environment.
65. Mechanisms Underlying Cytochrome P450-Mediated Inactivation of Aldehyde Oxidase by an Epidermal Growth Factor Receptor Tyrosine Kinase Inhibitor
Supervisor: Aik Jiang Lau
University: Dalhousie University (Halifax campus)
Location: Halifax, Nova Scotia
Start date: 2027-05-03 (flexible)
Disciplines: Biochemistry, Biological Sciences, Pharmacology, Pharmacy, Medical Sciences
Aldehyde oxidase (AOX1) is a cytosolic enzyme that is expressed predominantly in the liver. There is an increasing number of drugs and drug candidates that are metabolized by AOX1, and it contributes to drug-induced toxicities (e.g., nephrotoxicity). Therefore, this drug-metabolizing enzyme is gaining importance in drug development. However, relatively little is known about the mechanism of the functional interaction between AOX1 and drugs in clinical use.
Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) are anti-cancer drugs commonly used for non-small cell lung cancer. Our published findings indicated that EGFR-TKIs (gefitinib and erlotinib) and their in vivo metabolites decreased AOX1 catalytic activity by human liver cytosol (Tan et al., J Pharmacol Exp Ther 2020, 374: 295-307) and erlotinib is a potent clinically relevant mechanism-based inactivator of AOX1 (Kweh et al., Mol Pharmacol 2026, 108:100097). Our recent findings indicate that gefitinib and its in vivo metabolite (O-desmethylgefitinib) inactivated AOX1 by an indirect mechanism involving cytochrome P450 enzymes (CYP).
Objectives:
The aim of this project is to elucidate the mechanism by which gefitinib and its metabolite, O-desmethylgefitinib, inactivate AOX1 activity, and determine whether the CYP-mediated AOX1 inactivation by gefitinib and its metabolite is irreversible.
Methods:
The experiments will be conducted in vitro using various biochemical enzymatic assays in human liver fractions and human recombinant enzymes. The enzyme activity will be measured by quantifying the rate of enzyme-specific metabolite formation using highly quantitative ultra-high-performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS).
Significance and Implications:
The findings will provide a novel enzymatic mechanism of AOX inactivation and biochemical basis of AOX-mediated drug interactions in humans.
Research area, student roles & skills
Research area: My current research program is in the areas of drug metabolism, pharmacokinetics, functional pharmacogenetics/epigenetics, and toxicology. The overarching theme of my research program is to enhance our understanding of the mechanistic basis of individual variation in pharmacokinetics and pharmacodynamics, thereby contributing to personalized pharmacotherapy by improving drug effectiveness and safety in the individual patient. Specifically, the aim of my research program is to elucidate the various genetic and non-genetic factors (e.g., drugs/toxicants/endogenous chemicals, food, epigenetics) involved in regulating drug metabolism, transport, and action.
Student roles: The student will be involved in literature search/reading, planning of experiments, preparation of reagents (including calculations of reagents/chemicals and concentrations required for each step of the experiments), learning and performing experiments in the laboratory, writing of laboratory reports/notes, data analysis using Excel formulas, and statistical analysis using SigmaPlot software. As a member of the laboratory team, the student will also play a role in laboratory management tasks. The student may also be involved in presenting experimental findings in laboratory meetings and/or research symposium (if opportunity exists). The student will be trained to work independently on experiments. Some of the experimental techniques include preparation and dilution of chemicals, biochemical enzyme assays (enzyme kinetics), preparing standard calibration curves, and preparing samples for UHPLC-MS/MS analysis.
Skills required: The project requires highly quantitative experimental techniques to obtain accurate and precise data. The quantitative project is particularly suitable for students who are highly meticulous, highly organized, and with a very strong interest in pharmacology, drug metabolism, pharmacokinetics, or biochemistry. Students should have a background in pharmacy, pharmacology, biochemistry, biomedical sciences, biological sciences, or other related fields. Students with pharmaceutical analysis or bioanalytical chemistry and enzyme assay skills and knowledge will have an advantage in performing the experiments in this project.
66. Mechanisms implicated in the development of preeclampsia using animal models
Supervisor: Julie Lavoie
University: Université de Montréal
Location: Montréal, Québec
Start date: 2027-05-03 (flexible)
Disciplines: Biochemistry, Biological Sciences, Health Studies, Medical Sciences, Medicine, Molecular Biology, Physiology, Sports Science, Veterinary Science and Medicine, Pharmacology, Pathology, Genetics, Womens Studies
We are evaluating different components of the renin-angiotensin system and inflammatory parameters in various tissues in our animal models of preeclampsia in mice, which were sedentary or trained. For instance, we are investigating how these components are modulated at different time points during pregnancy to determine the optimal time to administer a novel treatment.
Research area, student roles & skills
Research area: My laboratory uses molecular biology/biochemistry methods to determine mecanisms implicated in preeclampsia, a gestational disease where mothers develop hypertension and proteinuria. We also use physical activity to evaluate the functional impact of these mecanisms as we have shown that exercise training can prevent preeclampsia in our animal models. Finally, we investigate the physiological progression of the disease using many methods such as by measuring blood pressure.
Student roles: The student will learn to extract RNA and proteins from different tissus and will learn to do real-time PCR and Western blots. He will also learn to extract RNA and to do regular PCR. Finally, the student will analyze his data and present them at our weekly laboratory meetings.

67. Mechanisms of neurovascular coupling in the diabetic retina
Supervisor: Sergio Crespo-Garcia
University: Université de Montréal
Location: Montreal, Québec
Start date: 2027-05-03 (flexible)
Disciplines: Biochemistry, Biological Sciences, Biology, Medical Sciences, Neuroscience
Diabetes is a metabolic condition characterized by high glucose levels (hyperglycemia) due to the body’s inability to produce or adequately respond to insulin. Diabetes can cause various long-term complications in many organs, including the retina. Diabetic retinopathy (DR) is a leading cause of blindness in working-age adults, and a third of diabetic patients worldwide will develop DR. In the retina, sustained elevated glucose levels cause microangiopathies and contribute to neuroinflammation, vascular permeability and neuronal death that translates to vision loss.
Although hyperglycemia is an indisputable driver of diabetic retinopathy, other risk factors are also at play. Arterial stiffness in large arteries (aorta, carotids), for instance, is emerging as a strong risk factor for CNS deterioration with aging. More importantly, several studies have showed that arterial stiffness occurs in pre-diabetes, and other epidemiological studies have demonstrated a link between arterial stiffness and worsened disease progression after the onset of diabetes. Although clinical evidence links increased arterial stiffness in major vessels (aorta, carotid) to the breakdown of the small vessels in the CNS (including the retina), we lack mechanistic understanding of 1) how arterial stiffness could exactly promote microangiopathies, including DR, and 2) whether resolving stiffness could serve as a preventive/palliative measure to diabetes complications such as DR.
This project will study the impact diabetic retinopathy in a novel model that combines hyperglycemia with arterial rigidity using histological and molecular approaches.
Research area, student roles & skills
Research area: The Crespo-Garcia lab at the School of Optometry (Université de Montréal, Canada) studies retina cell biology from a fundamental and translational angle. We are interested in understanding how different cells in the retina (vascular cells, neurons, glia) interact with each other, and how these interactions determine retina vascular disease and subsequent neurodegeneration. The candidate will be exposed to a dynamic and inclusive environment where is expected to be an active member of the team, learn new skills and have fun doing science.
Student roles: At the end of the internship, the student will have learnt key techniques to drive molecular and cellular biology research, including basics in cell culture of mammalian cells, Western blot and immunohistochemistry. The candidate will be responsible to direct their own research project and will perform literature research, experiments and analysis. The student is expected to develop critical thinking on the project and be proactive during the course of the research. There will be weekly meetings 1 on 1 with the mentor, but supervision will be available on a daily basis, particularly during the training phase. The candidate will become an integral member of the team, will present their results in a regular basis and participate in lab meetings. The candidate will be encourage to interact with other members of the team and learn from other ongoing projects in the lab or in the department. All the team works on keeping the lab as a safe and inclusive space and the candidate is expected to be respectful and emotionally responsible.
Skills required: The candidate must be familiar with principles in cell and molecular biology (mRNA, proteins, cell signalling, culture of mammalian cells) and preferably with background in the field of biomedical sciences (understanding of disease, more particularly of ocular pathologies involving the retina). Ideally, the candidate will benefit from having been enrolled at a BSc in Biology, Biomedical Sciences, Biochemistry or Medicine.
68. Modelling MELAS disease: a tunable system to silence a mitochondrial tRNA
Mitochondria carry their own small genome, which encodes the transfer RNAs (tRNAs) needed to build the machinery of cellular energy production. A single faulty mitochondrial tRNA can therefore disable energy metabolism and cause severe disease. MELAS, a mitochondrial disorder affecting the brain and muscles, is most often caused by one mutation, m.3243A>G, in the gene for mt-tRNA-Leu(UUR). Because cells carry many copies of the mitochondrial genome, symptoms appear only once the fraction of mutated copies passes a threshold, yet how tRNA loss tips cells across that threshold is poorly understood.
A major obstacle is that, in patient cells, the amount of mutation is fixed and cannot be adjusted. Our laboratory has solved this with peptide-morpholino chimeras that bind mt-tRNA-Leu(UUR) and reduce its activity in a controlled, dose-dependent way, effectively dialling tRNA function down on demand. The intern will use this tool to model MELAS. Working with cultured human cells, the intern will apply increasing chimera doses to recreate a range of tRNA deficiencies, then measure the effect on mitochondrial biogenesis, and quantify the targeted tRNA and the assembly of the respiratory complexes. Patient-derived MELAS cells will serve as a real-disease benchmark.
The 12-week objective is a clean, reproducible dataset relating the degree of mt-tRNA depletion to the decline in mitochondrial function: a focused, self-contained contribution to a larger program on mitochondrial RNA and disease. The project suits a motivated undergraduate: the core techniques are learnable within the first weeks, and the experiments produce clear, quantitative results that the intern will analyse and present.
Research area, student roles & skills
Research area: Our laboratory studies mitochondrial gene expression and RNA biology, focusing on mitochondrial transfer RNAs (mt-tRNAs) and how their dysfunction causes human disease. We developed a peptide-morpholino chimera platform that selectively silences individual mitochondrial RNAs in living human cells, and have extended it to mt-tRNAs to switch off mitochondrial protein synthesis in a controlled, dose-dependent way. Combining molecular biology, patient-derived cells, and real-time respirometry, we ask how defects in single mt-tRNAs collapse energy metabolism. The work connects directly to incurable mitochondrial diseases and is supported by a cellular metabolism platform.
Student roles: Under the day-to-day mentorship of the supervisor and a senior laboratory member, the intern will be a full participant in the project rather than an observer. After an initial onboarding and safety period, the intern will progressively take ownership of a defined set of experiments. Day-to-day, the intern will: • maintain human cell cultures and treat them with a dose series of the tRNA-targeting chimeras, alongside appropriate controls; • run mitochondrial respirometry assays on the Seahorse XF Pro; • extract RNA and quantify the targeted mt-tRNA; • assess assembly of the respiratory complexes; • compare the results with patient-derived MELAS cells. The intern will analyse the resulting data and keep a detailed, well-organised laboratory notebook, ensuring the integrity and traceability of their data. Throughout the placement, the intern will meet weekly with the supervisor, present progress at laboratory meetings, and take part in the lab’s journal club, developing the ability to read primary literature critically and to communicate results clearly. The intern will also complete the institutional safety and biosafety training required to work in the laboratory. We expect the intern to work carefully and independently while asking questions freely, and to contribute to the collaborative, supportive culture of the group. By the end of the 12 weeks, the intern will have learned a coherent set of molecular and metabolism techniques, generated and analysed an original dataset linking mt-tRNA depletion to mitochondrial function, and presented their findings to the group. Where the results support it, the intern’s contribution may feed into a future publication.
Skills required: We seek a student in cell or molecular biology, biochemistry, or a related life science, with: • coursework in cell biology and molecular biology or biochemistry; • some hands-on lab experience, ideally including cell culture or basic nucleic-acid work (full training provided); • basic data-analysis skills (spreadsheets, graphing; GraphPad or ImageJ/Fiji a bonus); • careful, organised work habits and reliable record-keeping; • a strong working knowledge of English (French welcome, not required); • curiosity, initiative, and the ability to work independently and in a team. Prior experience with mitochondrial methods is an advantage.
69. Modulating immune response in tumors via nanoparticle drug delivery
Supervisor: Shyh-Dar Li
University: University of British Columbia (Vancouver campus)
Tumor cells secret growth factors, cytokines and chemokines to drive the immune response in the tumor microenvironment towards pro-inflammatory, promoting tumor invasion and suppressing anti-tumor immunity. Immuno-modulation of the tumor microenvironment is an attractive strategy for antitumor therapy, but systemic delivery of immunomodulating agents often results in severe side effects. The Li lab plans to develop a nanoparticle system to target an immunomodulating agent to the tumor to re-educate the immune cells in the tumor microenvironment. It is hypothesized that this strategy will reduce the side effects, while exert enhanced anti-tumor immunity.
Research area, student roles & skills
Research area: Research in my lab focuses on developing innovative technologies to target drugs to the diseased site, enabling novel therapeutics.
https://lilab-tddn.pharmsci.ubc.ca/
Student roles: Work 40 hours a week. Perform experiments, report and discuss results, help maintain the lab, collaborate with other members in the lab, and write a final report.
Skills required: 1. Background in tumor biology and immunology (e.g. courses or summer project) 2. Cell culture 3. Cell based assays. e.g. MTT/XTT assay and ELISA 4. English proficiency 5. Microsoft Office (Powerpoint, Excel, Word)
70. Molecular Analysis of IRF1 Binding to Nucleosomes – insights into inflammatory gene program
Supervisor: Rashmi Panigrahi
University: Memorial University of Newfoundland (St. John's campus)
Macrophages are key immune cells that respond to infection and tissue damage by rapidly activating inflammatory gene programs. This process requires extensive changes in chromatin structure and cellular metabolism. Interferon Regulatory Factor 1 (IRF1) is an important pioneer transcription factor that drives macrophage activation in response to interferon-γ (IFNγ). IRF1 is rapidly induced during inflammation and can bind previously silent regions of the genome, suggesting that it can recognize DNA packaged within nucleosomes and promote chromatin opening. While primarily known for driving IFN responses, IRF1 can repress genes associated with cell cycle and tumor progression, acting as a tumor suppressor. However, the molecular basis of gene regulation by IRF1 remains unclear.
This project aims to determine how IRF1 interacts with nucleosomes, the fundamental units of chromatin composed of DNA wrapped around a histone protein core. IRF1 recognizes specific DNA sequences called Interferon-Stimulated Response Elements (ISREs). To investigate this interaction at atomic resolution, ISRE motifs will be inserted into different positions within nucleosomal DNA, including histone-contact regions and the DNA entry/exit sites. By comparing IRF1 binding across these nucleosome designs, the project will test whether IRF1 can engage DNA throughout the nucleosome or preferentially binds more accessible entry/exit regions. It will also examine whether IRF1 binding induces structural changes that increase chromatin accessibility.
Understanding how IRF1 remodels chromatin is highly relevant to immunity, as IRF1 controls inflammatory gene expression, metabolic reprogramming, and innate immune memory in macrophages. As abnormal IRF1 signaling has been linked to chronic inflammation, autoimmune disease, infection, and cancer, defining the molecular mechanisms of IRF1-nucleosome recognition may reveal new strategies for therapeutic control of inflammatory gene programs.
Research area, student roles & skills
Research area: My research focuses on uncovering the molecular mechanisms that control gene expression during key cellular processes. I study how genes are switched on or off through the binding and release of specific transcription factors at regulatory DNA elements. These interactions can reshape local chromatin architecture, alter DNA accessibility and influence downstream gene activity. By understanding how transcription factors and chromatin dynamics coordinate gene regulation, my work aims to provide deeper insight into normal development, cellular responses, and disease-associated changes in gene expression.
Student roles: This project investigates how the transcription factor IRF1 interacts with nucleosomes at a molecular level. The Panigrahi laboratory focuses on understanding chromatin regulation using biochemical and structural biology approaches to obtain atomistic insights into transcription factor–nucleosome interactions. The laboratory routinely expresses recombinant proteins using E. coli-based system. Expression constructs for IRF1 and human histones are already established in the lab. The student will work closely with Dr. Panigrahi and will receive hands-on training while performing the following experiments under direct supervision: 1. Recombinant protein expression and purification: E. coli strains will be used to overexpress histones and IRF1. The student will purify these proteins using chromatographic techniques, including affinity and size-exclusion chromatography. 2. Nucleosome reconstitution: DNA templates containing ISREs positioned at defined locations will be amplified using PCR. The purified DNA fragments will be used to reconstitute nucleosomes with site-specific positioning of ISREs to generate distinct chromatin substrates. 3. Biophysical and structural characterization: IRF1 binding to nucleosomes will be assessed using electrophoretic mobility shift assays (EMSA). Complex stability will be evaluated using thermal shift assays. Optimized IRF1–nucleosome complexes will be prepared for cryo-EM in collaboration with the Stanford S2C2 facility for grid preparation, screening, and data collection. Success of this 12-week project will be determined by formation of high-quality, stable IRF1–nucleosome complexes suitable for cryo-EM structural analysis. The student will be expected to attend weekly lab meetings and departmental seminars.

71. Molecular and Cellular mechanism influencing tumoral progression
Nearly 1 in 2 Canadians will receive a cancer diagnostic during their lifetime (www.cancer.ca). Recently, I discovered that a large sub-group of hereditary cancer syndromes are actually characterized by benign tumors that rarely progress to malignant tumors, syndromes that I reclassified as “hereditary benign tumor syndromes”. The archetype is a rare genetic disorder named Neurofibromatosis type I (NF1). Ninety-nine percent of NF1 patients develop characteristic benign lesions by the age of 20. The reason why they rarely if ever progress to a malignant state is an elusive question. I propose to study and learn from benign tumors that are naturally refractory to malignant progression to get novel mechanistic insights with regards to the benign-malignant progression that could be conceptually transposed to any cancer type.

Heme has a wealth of functions in biological systems, making it an essential micronutrient for all living organisms. Defects in heme homeostasis are directly responsible for diseases, and have been tied to impaired development, metabolic syndromes and fungal virulence. Consequently, it is critical to gain a comprehensive understanding of the molecular bases of heme-dependent proteins in living systems. The research project will use a model system to decipher the interplay between important proteins involved in heme acquisition. Furthermore, inhibitors will be tested as potential anti-fungal drugs against heme-dependent proteins as they are required for invasion of fungal cells.
Our studies use the model organism S pombe. This yeast, unlike S cerevisiae, can assimilate exogenous heme, allowing the use of the power of genetics to selectively block heme biosynthesis, setting conditions to investigate the mechanisms by which external heme is taken up by the cells. Our studies have revealed the existence of genes encoding proteins that have novel functions in heme assimilation, yet little is known about them, including their mechanism of action and how they are regulated in response to changes in heme levels.
Students trained under this program will acquire education/training in multidisciplinary approaches, including areas of yeast genetics, molecular & cellular biology, biochemistry, next-generation sequencing & mass spectrometry. Students without distinction as to minorities will develop critical skills, allowing them to gain the status of highly trained scientists for the Canadian biotech sector &/or academic research community.
Research area, student roles & skills
Research area: The long-term goal of this proposal is to decipher the molecular basis of heme acquisition in eukaryotes. Due to its critical physiological role as a cofactor for several essential cellular enzymes, organisms have evolved with two different ways to obtain heme: heme biosynthesis and heme uptake from external sources. As opposed to the well-characterized enzymes responsible for heme biosynthesis, knowledge of the players and mechanisms involved in acquisition of exogenous heme is very limited and remains poorly understood. Studies in the Labbe’s group are aimed at filling this gap in our knowledge.
Student roles: The student will be involved in a research projet in which he/she will have to apply molecular and cellular approaches to perform biological experiments. The student will develop her/his own sub-project to gain independence and autonomy skills.
The students involved in the proposed research program will learn a broad spectrum of experimental approaches, including new proteomics strategies and several applications involving next generation sequencing for genome-wide analysis of gene expression changes. Although each student will primary work on a specific aim, collaboration between students will be highly encouraged to ensure that they gain mastery over all the laboratory methods.
Each week, we have a: Lab meeting: a member describes her/his results and experimental problems in order to exchange ideas and receive constructive criticism. Journal club: to discuss and comment publications relevant to our field or other areas.
Departmental group seminar: the graduate students are exposed to "tell a story" and exchange about their results with other graduate students and professors of the Department.
Skills required: Highly interested student who is eager to learn molecular and cellular biology as well as yeast genetics. New generation sequencing (NGS) approaches (e.g. RNA-Seq) will be used and a combination of bioinformatics tools will be available for the trainees.
Our working model is the nickel uptake system of Helicobacter pylori, one of the most successful human pathogens, causing mild to severe gastric pathologies accounting for about one million deaths per year worldwide (mostly cancers). The bacterium is notably considered a leading cause of gastric cancers and MALT lymphoma, as such the World Health Organization identifies H. pylori as a group 1 (definite) carcinogen, and experts estimate that 1 to 3% of the infected population will develop gastric carcinoma, a pathology with poor prognosis (15% survival 5 years after prognosis) representing the third most common cause of death by cancer. The bacterium colonizes the stomach of 50% of the worldwide population where the pathogen survival relies on its ability to scavenge nickel from the gastric milieu. Helicobacter pylori eradication is advised as first-line therapy in early stage disease of gastric MALT lymphoma, complete remission is achieved in 75% of cases, but the treatment is effective with a limited number of antibiotics that are active in the stomach.
Nickel transporters in H. pylori are of notable medical relevance as they display critical nickel-uptake function enabling colonization of the host, but also serve as passageway for bismuth-based therapeutics currently used in H. pylori eradication regiments. The research project investigates the transport mechanisms of nickel and bismuth-derivative drugs across the membranes of H. pylori using structural biology and biochemical approaches. We aim at accelerating research on these medically relevant proteins by elucidating their structures and functional mechanisms to promote the discovery of innovative strategies to treat the burden of H. pylori associated cancers. The research project will contribute to develop novel anti-pylori molecules, and improve current bismuth-based therapies, which are much needed to overcome the emergence of resistant H. pylori strain

75. Molecular mechanisms of obesity-induced cardiac dysfunction - role of lysophospholipase signaling_Clone
Supervisor: Petra Kienesberger
University: Dalhousie University (St. John campus)
Metabolic disorders, particularly insulin resistance and type 2 diabetes, are believed to be primary causative factors for
obesity-induced heart disease, which accounts for 11%-14% of heart failure cases. Insulin resistance and diabetes can
precipitate “metabolic cardiomyopathy”, which is characterized by changes in metabolism, structure and function of the
myocardium that are not directly attributable to confounding factors including coronary artery disease and hypertension.
Understanding the pathogenesis of this form of cardiomyopathy is important considering the current obesity and diabetes
epidemic, which is expected to lead to a sharp increase in the prevalence of metabolic cardiomyopathy in the near future.
Currently, no adequate therapies are available for obesity-related metabolic cardiomyopathy. The overall goal of this research
is to identify signalling pathways in cardiomyocytes that not only play a critical role in the development of metabolic
cardiomyopathy, but also exhibit great potential for therapeutic targeting. The lysophosphatidic acid (LPA) signalling pathway
has been implicated by our group and others in obesity-related metabolic dysfunction. LPA is a bioactive lipid which
stimulates cell signalling through G protein-coupled receptors. Several LPA receptor modulators have been developed that are
in clinical trials or have been approved for the treatment of idiopathic pulmonary fibrosis, systemic sclerosis, and multiple
sclerosis, demonstrating that LPA signalling modulators have promising therapeutic potential in chronic inflammatory
diseases. Lipid phosphate phosphatases (LPPs) are integral membrane proteins that dephosphorylate intra -and extracellular
lipids including LPA. Decreases in LPP3 function and the subsequent surge in LPA levels in the vasculature are a major
contributor to the development of atherosclerosis and coronary artery disease. More recently, LPP3 has also been implicated in
the regulation of energy metabolism. Adipose-specific LPP3 inactivation improved glucose homeostasis in mice fed a
cholesterol-rich diet. Moreover, heart-specific LPP3 deletion perturbed mitochondrial ultrastructure and decreased respiration
and ATP production in neonatal murine cardiomyocytes.
Research area, student roles & skills
Research area: My research focuses on cardiac metabolism and pathophysiology. I am examining molecular mechanisms of cardiomyopathy induced by metabolic disorders, such as obesity and type 2 diabetes.
Student roles: The student will perform cell culture studies and work with tissues from mice subjected to diet-induced obesity. In addition, the project entails immunoblot analyses of proteins involved in LPA signaling. The student will also examine cardiomyocyte function by measuring sarcomere shortening using a specialized microscope. In addition, the student will perform enzyme activity assays.
Skills required: The student would need to have some experience in working in a research laboratory. Students with a background in biochemistry and/or cell biology are preferred.
76. Molecular mechanisms regulated by the guidance cue netrin-1 during neuronal development
During development, axon growth and pathfinding of the central nervous system are governed in part by environmental guidance cues. Molecular signals initiated by these cues are transduced intracellularly by means of conserved receptors expressed at the growth cone, ultimately resulting in modulation of the actin cytoskeleton. The netrin family of guidance cues is vital in neural development of both vertebrates and invertebrates. In particular, netrin-1 has the ability to attract or repel axons via several receptors, including the Deleted in Colorectal Cancer (DCC) family (DCC and neogenin), DSCAM, the UNC-5 family, and amyloid precursor protein. During development of the spinal cord and cerebral cortex of vertebrates, netrin-1 exerts its attractive functions through the receptor DCC. In humans, mutations of the DCC gene have been associated with congenital mirror movement, and small nucleotide polymorphisms within the genes encoding DCC and netrin-1 have been associated with schizophrenia, Parkinson’s disease and amyotrophic lateral sclerosis.
The Rho family of small GTPases- in particular, RhoA, Rac1, and Cdc42- act as molecular switches that control many aspects of cell activity through a simple GDP/GTP cycle. They exist in either an inactive GDP-bound or an active GTP-bound conformation, which is regulated by Guanine nucleotide exchange factors (GEFs) and GTPase-activating proteins (GAPs). Our recent work pinpoints on the intricate regulation of the small GTPases Rac1, RhoA, and Ras in netrin-1/DCC-induced signaling pathways. In this project, we will use a combination of in vitro and in vivo approaches using primary neuronal cell cultures and mouse models to dissect these various pathways activated by netrin-1 and to determine how they regulate actin dynamics resulting in a directed response of growth cone navigation.
Research area, student roles & skills
Research area: Dr Lamarche-Vane’s lab investigates molecular mechanisms involved in the regulation of cell migration and adhesion, linked to development and human diseases. For instance, in the adult, migration events are involved in the normal physiology as well as in pathology such as metastasis. In embryogenesis, cell migration is an important feature of the development of the nervous system. Dr Lamarche-Vane is interested to uncover novel mechanisms underlying the role of the Rho GTPases in cell migration, in particular, in the developing nervous system and in the cellular processes leading to metastasis using global molecular and cellular approaches.

The student will learn how to critically analyze the data, how to organize them and will meet with Dr Lamarche-Vane every week to discuss the data and the follow-up strategies.
Skills required: The student should have some basic knowledge of molecular and cellular biology. Some background in the basic signaling mechanisms involved in the regulation of cell proliferation and cell migration will help but is not absolutely essential.
77. Monodisperse, size tunable Au nanoparticles as functionalized surfaces for biosensors
Supervisor: Ayse Turak
University: Concordia University (Montréal campus)
In this project, students will utilize novel nanoparticle patterning and surface functionalization methods to increase the density of biorecognition elements and provide enhanced exposure of active sites for protein binding. The research project will target measurements of the thyroid function, utilizing nanoparticle approaches to detect thyroxine, specifically T3, T4, TSH and related antibodies. Incorporation into a biosensing platform will open up many new opportunities with revolutionized accessibility, as it paves the way for portable, point-of care sensors, particularly useful for Canadians with vulnerable immune systems, mobility issues, or those residing in remote locations.
Tunable Au nanoparticles will be produced using the reverse micelle method. As both nanoparticle size and spacing are critical to achieving specific binding, the student will optimize the size, particle separation and 2D order of the nanoparticles for enhanced binding of proteins on the surface. They will produce particles ranging from 3nm to 70nm, by modifying deposition methods, molecular weight, and solvent. These nanoparticles will be applied directly to gold (Au) plated silicon and glass substrates for direct use, and to polydimethylsiloxane (PDMS) surfaces for integration with microfluidics. The initial use of Au allows conjugation with thiol functionalized species such as self-assembled monolayers (SAMs) and provides an optimal material for various surface characterization techniques.
Research area, student roles & skills
Research area: The Turak Functional Nanomaterials Laboratory seeks to revolutionize biosensors by making them cheaper, more accessible, and more flexible. Our research focusses on developing easy, versatile, and inexpensive methods of exploring and tuning surfaces using nanoparticle functionalization. To achieve this vision, the Turak group uses simple manufacturing approaches (reverse micelle deposition), allows nature to dictate morphology (entropic self-assembly, beneficial dewetting), and develops characterization tools that are widely applicable to nanotechnology.
Student roles: Students will characterize the nanoparticles properties, focusing particularly on size, using atomic force microscopy, scanning electron microscopy, UV/Vis absorption, and surface plasmon resonance techniques.
Skills required: Ideally the student will have some experience in material synthesis in solution, and some understanding of self-assembly. Bonus if they have some experience with thiol functionalization.
A major challenge remains in the advancement of nanobubble technology; current methods for measuring nanobubbles only work in pure water and cannot distinguish nanobubbles from other particles in complex water mixtures like wastewater. Consequently, many nanobubble technologies cannot be translated from ideal laboratory conditions to complicated, real-world systems.
The Kimura-Hara group has developed a novel technology called SONIC (Speed of Sound Measurement for Nanobubble Characterization) that uses sound waves to distinguish nanobubbles from solid particles. The group’s goal is to use SONIC in wastewater treatment. For SONIC to be applied in wastewater treatment, however, it must be able to selectively measure nanobubbles in more complex water systems. Currently, it is unknown how SONIC performs in such environments.
A principal goal of this project is to iaddress this knowledge gap by 1) analyzing different wastewater components that affect SONIC’s ability to selectively measure nanobubbles, and 2) make modifications to SONIC for real-world applications and 3) compare results with another a widely-used technique for nanobubble characterization known as, nanoparticle tracking analysis (NTA).
Research area, student roles & skills
Research area: Nanobubbles are gas-filled bubbles in water with typical diameters in the ~100 nm range. Nanobubbles in bulk aqueous solution have only recently come under focused scientific investigation. While many questions remain regarding bulk nanobubbles, they possess several consistently reported features, most notably being stable in water over long periods (e.g. months). Nanobubbles have potential for tremendous impact across a wide range of application areas that rely on gases dissolved in water, ranging from water treatment and environmental applications to energy innovation and food production, and hence their investigation has triggered considerable interest and excitement.
Student roles: The student intern will work closely with a senior lab member on the evaluation and re-design of SONIC and also characterize the nanobubbles solutions using acoustic measurements, and nanoparticle tracking analysis. The student intern will interact closely with a team of a postdoc, graduate student and professors.
Skills required: This project requires one highly enthusiastic and self-motivated student with background in engineering, physics, or chemistry/material science that has taken analytical chemistry courses, has wet laboratory experience (prepare solutions, analytical balance, pH meter), and familiar with instruments (i.e., UV-Vis). Students must be proficient in English, and Microsoft Office software including Excel and Word. A student with background in engineering that has knowledge in acoustics, physical chemistry, and transport phenomena is a plus.
79. Natural Hydrogen Cycle in Subsurface Geochemical Systems: A Unified Model
This project aims to develop a unified model to simulate the geochemical hydrogen cycle in subsurface environments by integrating key H2 production, transformation, and consumption processes. The model will focus on primary water-rock-interaction mechanisms that generate or consume hydrogen over geological time, including sperpentinization and radiolysis as dominant production pathways. It will explicitly address how variations in geochemical conditions–such as pH, temperature, mineraology, water availability, fluid composition, and radionuclide content–can control the rate of these processes and, ultimately, the net H2 production rate. The results will improve our understanding of natural H2 occurrence, inform exploration strategies for geological hydrogen resources, and provide a predictive framework for evaluating subssurface hydrogen systems in both natural and engineered settings.
Research area, student roles & skills
Research area: My specialized research areas include geochemistry and contaminant hydrogeology.
My current geochemistry research focuses on how long-term water-rock interactions on Earth drive the natural formation and transformation of geochemical species such as H2, CH4, and simple organic compounds. This research is important for understanding early Earth habitability, natural H2 formation as a potential green energy source, and pathways for greenhouse gas transformation
Student roles: Literature review, database construction, and a little bit of coding
Skills required: This project invites motivated student to work on geochemical simulation of the natural hydrogen cycle in subsurface systems. The student will begin with an extensive literature review and will gain knowledge and hands-on experience in geochemical modeling, kinetic rate laws, and reactive transport concepts. Your work will contribute to novel research at the interface of geology, aquatic geochemistry, and energy sciences. Students with geochemistry or chemistry background are preferred. Prior modeling skills are not required, but experience with Python or Matlab will be an asset.
80. Natural Polymer-Based Hydrogel Dressings for Treating Infected Wounds
Developing dressings that can prevent the infection of wounds and/or effectively resolve wound infections if they occur remains a critical need in medicine. Typically, the successful design of such dressings requires proper selection of both (1) the base material of the dressing and (2) the type of anti-infection agent(s) incorporated in the dressing. The use of hydrogels as the base dressing material is particularly appealing given that hydrogels can maintain a moist environment at the wound to promote healing while also mediating the degree of adhesion of the dressing to the wound to balance ease of removal with barrier function. Our lab has a particular focus on valorizing naturally-derived materials, specifically guar gum (a plant-derived carbohydrate with anti-adhesion and pro-healing properties) and canola protein (a waste product of canola oil production with strong anti-oxidant properties) as the base material. The anti-infective material must be chosen to be compatible with the dressing and to maximize the breadth of the types of pathogens that can be killed while minimizing resistance development, the latter being particularly important given the emerging antibiotic resistance crisis. Our lab is developing functional polymers with inherent anti-infective functionality based on quaternary ammonium and/or chelating groups as well as micro/nanoparticles that can be loaded with established antibiotics and control their release based on the progression of a wound infection (i.e. more drug is released as infection worsens). In the proposed research project, the student will focus on combining our lead dressing materials with our lead anti-infective materials and/or delivery vehicles into a single bioactive natural polymer-based wound dressing that can both enable broad-spectrum anti-bacterial activity as well as promote functional wound regeneration, both to be validated by a combination of in vitro and in vivo models.
Research area, student roles & skills
Research area: The Hoare lab is a world leader in the rational engineering of smart, environmentally-responsive materials, with an emphasis on materials suitable for biomedical applications such as drug delivery and tissue engineering. Smart materials in the context of our work refer to materials whose physical properties can be triggered to change reversibly by a change in the environment (i.e. pH, temperature, the concentration of a particular chemical) or the application of an external signal (i.e. a magnetic field, near-infrared light, or ultrasound). Our lab performs novel polymer/nanoparticle synthesis to improve such vehicles, including using small animal models to confirm biological functionality.
Student roles: The student would be paired with a PhD student in my lab who is driving this project. The PhD student would provide hands-on mentorship and direction for the student on a day-to-day basis, initially via co-run experiments and then by being available for help on an as-needed basis. The student would perform several experimental tasks: (1) isolate and/or functionalize the natural polymer-based hydrogel precursor materials (molecular weight, degree of functionalization, type of functionalization); (2) fabricate and characterize the physicochemical properties of the resulting hydrogels (gelation time, mechanics, degradation time); (3) synthesize and characterize the anti-infective material and/or delivery vehicles via both physical measurements (e.g. molecular weight, degree of functionalization, particle size, particle structure, drug loading capacity) and biological measurements (e.g. zone of inhibition or contact killing testing on common wound bacteria); and (4) assess the biological compatibility of the hydrogels via cytocompatibility testing and (time permitting) in vivo infected wound mouse models to assess both infection management and functional tissue regeneration. The student will be responsible for co-planning experiments with their mentor, collecting/organizing/analyzing the resulting data, and preparing short reports summarizing their data aiming for a future publication and/or patent application. In addition to these research tasks, the student would be expected to participate in all lab activities (including social events, seminars/local conferences, and our weekly lab group meetings), including the presentation of a short (10-15 minute) talk at the end of the placement on their research results. The student would also help with routine lab tasks (e.g. safety inspections, lab cleaning, supplies and waste management) and have the opportunity to participate in entrepreneurship activities through our wound healing-focused start-up company and/or professional development workshops organized via a CREATE program to accelerate career readiness in the field of applied biomaterials.
Skills required: The student should have a chemistry, chemical engineering, or biomedical engineering background, although biochemistry and related sciences will also be considered if strong aptitude and interest is shown. The student should have demonstrated a strong record of scholarship. Some previous laboratory experience is preferred, with that experience ideally coming in a polymer chemistry and/or polymer characterization laboratory setting; however, strong candidates will be considered even without prior experience in a lab.
The intern will assist in the synthesis, testing, and validation of novel solid-phase extraction materials using non-conventional platforms, including DNA aptamers, metal chelators, and molecularly imprinted polymers (MIPs, also known as "plastic antibodies"). The project involves utilizing advanced analytical instrumentation to characterize synthesized materials and quantify extracted targets, with a focus on cross-validating results to ensure accuracy and reproducibility. This work provides hands-on experience in cutting-edge materials science and analytical chemistry. The project’s outcomes have broad applications across the agri-food, biomedical, and petrochemical industries, including food safety testing, water quality monitoring, and wastewater treatment processes.
Research area, student roles & skills
Research area: Solid-phase extraction (SPE) is a critical technique for the enrichment, recovery, and removal of (bio)chemical targets. Current methods often rely on synthetic plastics or silicon-based sorbents, which can be cost-prohibitive and environmentally taxing. This research focuses on developing a new generation of sustainable, biocompatible, and cost-effective SPE sorbents. By leveraging novel materials, we aim to bridge existing performance gaps in conventional approaches, creating more efficient tools to capture, concentrate, and control high-priority targets within both biological and environmental contexts. This project will explore the design and synthesis of these advanced sorbents to improve analytical performance and environmental sustainability.
Student roles: The intern will actively participate in method development and daily laboratory operations alongside research assistants and fellow students. Responsibilities include performing chemical reactions, conducting chemical analyses, and analyzing and presenting experimental data to the team. The intern is expected to attend and report progress at weekly meetings and deliver a 20-minute oral research presentation to a broad audience in August. Throughout the internship, the student must strictly adhere to Concordia University of Edmonton’s code of conduct and established laboratory safety protocols to ensure a productive and secure research environment.
Skills required: The ideal candidate should have a solid foundation in general chemistry, basic laboratory skills, and proficiency in experimental data analysis software such as Microsoft Excel. While not required, prior training in analytical or synthetic chemistry is a significant asset, and experience with laboratory instrumentation or a "DIY" approach to problem-solving is strongly preferred. Throughout the internship, the student will receive hands-on training in one or more techniques, such as FTIR, HPLC, GC-MS, and XRF. The intern will gain practical experience in experimental design, sample collection and preparation, as well as chemical product development and testing.
82. Optimization of a 3D-printed platform for bacteriophage functionalization to develop antimicrobial and bacteria detection technologies
Infectious diseases are a great challenge for global health; unfortunately, bacterial diseases like pneumonia, tuberculosis, blood poisoning and foodborne diseases are becoming hard to treat. Additionally, pandemic and epidemic outbreaks call for innovative strategies to develop prevention, control and diagnostic technologies. Bacteriophages (phages)—bacteria-infecting viruses—have re-emerged as an appealing approach. By combining phages with appropriately designed materials, we aim to use phages in antimicrobial and diagnostic devices. To this end, it is of primary importance to establish a platform for the systematic study of phage immobilization on surfaces, to optimize the production of phage-enabled bioactive materials.
We are developing a 3D-printed substrate for phage functionalization; by using 3D printing, the effects of a vast array of input gradients can be studied in parallel, as it allows the rapid production of complex, repeatable and detailed structures. The overall objective of this project is to optimize and validate the platform. First, based on our initial prototype, 3D models will be designed and further prototypes (e.g., in different materials) will be fabricated. Then, the platforms will be treated with different techniques to optimize phage functionalization parameters (e.g., density, orientation). Secondly, the treated platforms will be characterized through material characterization techniques. Then, tests of phage immobilization will be run to demonstrate efficacy (e.g., co-immobilization of phages of Escherichia coli, Pseudomonas aeruginosa and/or Methicillin-resistant Staphylococcus aureus (MRSA) for antimicrobial surface applications). This will include quantification of phage surface density, orientation, and activity against the target bacteria under varying combinations of conditions (e.g., temperature, pH, humidity) applied concurrently to the platform.
This system will introduce a high-throughput approach to the study of phage incorporation on materials. Thanks to 3D printing, this design will be readily adaptable to other materials, phages and applications. This will be the basis for an important tool in phage R&D.
Research area, student roles & skills
Research area: The project deals with the optimization of a platform for the functionalization of bacteriophages ("phages" in short, i.e. viruses that infect bacteria but not humans) on materials, which has the potential of leading to the development of technologies for prevention and diagnosis of bacterial diseases. The project will be conducted under the supervision of Professor Ilaria Rubino, who specializes in phages, phage engineering, and antimicrobial materials. The student will be co-supervised by Professor Marc-Antoine Lauzon, who has extensive expertise in 3D printing techniques and biomaterials.
Student roles: Student’s role: 1) Literature review: the student will familiarize themselves with phage functionalization techniques, material options, 3D printing techniques, surface treatment techniques, requirements of the targeted applications, and challenges; 2) Platform design: the student will conceive and create 3D models of substrates for phage immobilization allowing for the systematic study of input gradients; 3) Fabrication: the student will operate the 3D printers for prototyping; 4) Surface treatment: the student will treat the surface of the substrates; 5) Characterization: the student will characterize their products (e.g., surface morphology, topography, composition, hydrophilicity). 6) Phage functionalization: the student will use physical or chemical functionalization techniques to immobilize phages on their proof-of-concept platform. 7) Performance evaluation: the student will evaluate the phage surface coverage (e.g., scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS)), activity (e.g, plaque assay, infection dynamics), and efficacy (bacterial burden reduction). 8) The student will analyze and summarize their results. The project will be mainly conducted in the laboratories of Professors Rubino and Lauzon, and of the Chemical and Biotechnological Engineering Department (Faculty of Engineering of the Université de Sherbrooke). The work environment aims to provide opportunities for initiation and consolidation of students’ research skills. The interpretations and ideas of all group members are taken into consideration and greatly encouraged. Professors Rubino and Lauzon will provide supervision on the phage and 3D printing techniques, respectively. All necessary training will be provided. The student will be invited to share their questions and results during weekly meetings. The student will have the opportunity to interact with the Department's technicians, and will have access to a desk and all necessary equipment. The student will plan their research work, ensuring a flexible schedule; if needed, the dates of beginning and end of the internship could be modified. The results could lead to a scientific publication.
Skills required: Introductory knowledge on the following topics would be an asset, but not a requirement: (i) 3D printing: software for design of 3D models, fabrication; (ii) Material characterization: microscopy, SEM sample preparation, image analysis, composition analysis; (iii) Chemistry and biochemistry: functionalization techniques (e.g., physical adsorption, electrostatic interactions, covalent bonding); (iv) Microbiology: bacteria cultures, phages.
83. Organic matter characterization in deep-ocean sediments
This research project investigates deep-ocean sediments deposited at water depths of approximately 3000–5000 m during the Eocene–Oligocene Transition (EOT), one of the most significant climate reorganizations of the past 50 million years. The project focuses on organic matter found in deep-water red clays and nannofossil ooze recovered from South Atlantic deep-sea cores IODP Exp. 390 and 393. These cores serve as valuable archives of paleoceanographic and climatic change associated with the transition from greenhouse to icehouse conditions.
The study integrates sedimentology, sedimentary geology, and geochemistry to reconstruct changes in deep-ocean environmental conditions and circulation patterns during the EOT. A multi-proxy approach will be employed, including Rock-Eval pyrolysis, total organic carbon (TOC), bulk stable carbon isotope (δ¹³C) analyses, and, where feasible, bulk sulfur isotope (δ³⁴S) measurements. These datasets will be combined with lithological and ichnofabric observations to refine interpretations of trace fossil assemblages and benthic ecosystem responses across the transition. We hope to better constrain changes in bottom-water oxygenation, microbial sulfate reduction, organic matter flux, ocean stratification, and deep-water ventilation. Geochemical results will also be compared with other paleoproductivity proxies to evaluate changes in organic carbon export to the deep sea and associated redox conditions. This work shall improve our understanding of how deep-ocean environments and benthic ecosystems responded to major climate-driven reorganizations of ocean circulation during the EOT.

This work integrates sedimentology, sedimentary geology, and geochemistry to reconstruct changes in deep-marine environments and ocean circulation. A multi-proxy approach will be employed, including Rock-Eval pyrolysis, total organic carbon (TOC), bulk stable carbon isotope (δ¹³C) analyses, and, where feasible, bulk sulfur isotope (δ³⁴S) measurements to characterize variations in organic matter preservation, redox conditions, and paleoceanographic processes across the EOT.
Student roles: The successful candidate will conduct some or all of the analyses outlined above and will work collaboratively between the University of Manitoba (laboratory analyses) and Western University (data processing, interpretation, and synthesis) under the guidance of two supervisors. You are expected to develop a project timeline, set dates for lab work and travel, conduct literature research, do lab work, analyze the data, and prepare a final report following a journal article format. The candidate is expected to demonstrate curiosity, initiative, and strong motivation for interdisciplinary research.
Skills required: The student is required to have a good understanding of sedimentology, geochemistry, and paleoceanography gained as part of a bachelor's degree in Geology or Earth sciences. Hands-on experience with isotope analysis and organic matter characterization are very welcome.
84. Organic synthesis and biochemical characterization of novel carbohydrate active enzymes
Students will learn develop autonomous research and problem solving skills. The students will be given a specific project - characterizing a specific enzyme involved in carbohydrate processing. The student may use multi-step chemical synthesis to prepare a new substrate or inhibitor, or the student may develop an assay and measure the Michaelis-Menten parameters for a specific enzyme. Assays may involve UV, HPLC, TLC or NMR analysis. The research project will be written up by the student in English with a view to publishing novel research results.
Research area, student roles & skills
Research area: The research laboratory focuses on understanding the chemistry and biochemistry of enzymes involved in metabolizing carbohydrates in bacteria. Studying these enzymes will result in new insight into the mechanism of action, the structure and the function of these catalysts. These enzymes are potentially drug targets. Potent inhibition is a potential avenue towards developing new antibiotics. The laboratory uses a wide variety of chemical techniques, organic synthesis, carbohydrate chemistry, enzymology, HPLC, TLC, NMR, gene cloning and protein engineering. Students will be exposed to some or all of these techniques.
Student roles: The student will conduct all of the experiments, with assistance from a graduate student or post-doctoral fellow present in the laboratory to assist with day-to-day queries. The student will write up their research findings daily in their laboratory notebook. This will be reviewed by the supervisor and more senior researchers on a daily basis. The student will be required to present their research findings daily to their supervisor in English. They will be required to prepare weekly powerpoint presentations outlining their productivity and present to the research group (up to 10 graduate students and post-doctoral fellows). They will be required to write an end of experience report.
Skills required: Students need to have strong quantitative lab skills, understand the principles and practical aspects of organic synthesis, be familiar with TLC and HPLC, UV visible spectroscopy and 1D and 2D NMR spectroscopy. Understanding the theory of these techniques is a requirement. Potential students need to demonstrate in their application how their current experiences demonstrate this knowledge. Hands-on training for the techniques will, however, be provided.
Ozone is predominantly used in water treatment for disinfection (pathogen inactivation), taste and odour control, and degradation of persistent micropollutants. However, despite ozone’s advantages, its application carries serious unintended consequences. Ozone can also oxidize naturally occurring bromide to bromate, a compound classified as “possible human carcinogen”, with a Canadian maximum concentration guideline of 10 µg/L in drinking water. Due to ozone’s propensity to form highly toxic by-products, this project will evaluate the formation of bromate generated from bromide-containing waters treated with ozone nanobubbles and conventional ozonation at different water quality conditions (pH, organic matter concentration). Results between both treatments will be analyzed and compared. Insights from this research will help us understand the potential risks associate with ozone-nanobubbles and accelerate the application of these innovative technology in water treatment.
Research area, student roles & skills
Research area: Nanobubbles are gas-filled bubbles in water with typical diameters in the ~100 nm range. Nanobubbles in bulk aqueous solution have only recently come under focused scientific investigation. While many questions remain regarding bulk nanobubbles, they possess several consistently reported features, most notably being stable in water over long periods (e.g. months). These unique features can transform a wide range of processes that are currently limited by gas solubility. For example, ozone-containing nanobubbles can increase the concentration of ozone in water disinfection and therefore significantly decrease the required amount of energy and emission footprint when compared to conventional ozonation treatment.
Student roles: The student intern will work closely with a senior lab member on the generation of solutions containing ozone-nanobubbles and ozone. The intern will need to prepare bromide and bromate solutions from analytical standards and construct a calibration curve on an ion chromatography. Then, the intern and graduate student will be spiking bromide into two reactors containing ozone-nano bubbles and ozone and taking samples over time. Samples will be analyzed for bromide and bromate concentration with ion chromatography and for bubble size and population using an nanoparticletracking analyzer. This project will provide the intern with hands-on experience on the use of two analytical instruments and design of experiments. Furthermore, the student interns will Interact with a team of postdocs, graduate students, and professors.
Skills required: This project requires one highly enthusiastic and self-motivated student with background knowledge in engineering and/or chemistry that has taken general chemistry and has wet laboratory experience (prepare solutions, analytical balance, pH meter). Students must be proficient in English, and Microsoft Office software including Excel and Word. Students ideally would have taken analytical chemistry (understand and know how to construct a calibration curve) and experience with ion chromatography and colorimetric methods is a huge plus.
86. Polymer nanoparticles for stopping the progression of Alzheimer's disease.
The objective of this project is to develop therapeutic polymer nanoparticles that will reduce the amount of glutamate in the brain to a `normal' level, over a period of 1 -3 weeks after a single administration. Re-administration of the nanoparticles at regular intervals will contribute to maintaining `normal' levels of brain glutamate, which could stop or slow the progression of AD.
Research area, student roles & skills
Research area: Alzheimer's disease (AD) is the most common age-dependent neurodegenerative disorder, and afflicts more than 44 million individuals worldwide. One of the hallmarks of AD is the presence of excess glutamate in the brain. Glutamate, a neurotransmitter, is the most abundant free amino acid in the central nervous system. Unfortunately, when present in excessive amounts, glutamate becomes toxic and, via a complex set of processes, leads to cognitive impairment. The latter can involve problems with memory, language, thinking, and judgment, which are greater than normal age-related changes.
Student roles: Read associated literature, conduct experiments (under supervision of senior lab member), interpret results, write a final internship report (10 pages), and make a final oral presentation to lab members (10 min).
Skills required: All associated techniques will be taught on-site. Background in chemistry, biochemistry, or biology are seen as most appropriate for capitalizing upon this learning experience.

Disciplines: Biochemistry, Chemistry, Chimie, Engg-Chemical, Engg-Materials, Science Politique
In this project, visiting exchange student will work closely with other lab members, on the synthesis of novel ligands and their deposition on surfaces. We will determine binding affinities and establish stoichiometry of the coordination of the ligand to a variety of metal ions. Self-assembled monolayers formed from these novel ligands will be further interacted with aqueous solutions of suitable metalloproteins. The exchange students who advance this research will learn organic, inorganic, analytical, physical, and surface chemistry; will get strong experience in applying their knowledge to design new materials starting from synthesis of molecular building blocks, assembly them using various binding motifs, and analyze the optical response of the developed sensor interacting with a variety of analytes.
Metal binding affinities, surface coverage, porosity, stability, electrocatalytic, redox, electrochromic and spectroscopic properties will be optimized. Chemical modification of the ligand will allow for the incorporation of metals of different sizes that will define the hydration shell and as a result, the properties of the SAM. Various functional motifs could be introduced into one multidentate ligand to simultaneously detect different metals and allow real-time simultaneous detection and quantification of various analytes in multicomponent systems.
Once the binding and detection of single metal ions are well understood on support, we will then prepare sensing arrays able to analyze multicomponent systems. Mixed molecular assemblies with a homogeneous distribution of key functionalities will be prepared by 1) co-deposition, when few functionalities competitively absorbed on the same solid support; or 2) stepwise deposition where large templating molecule are pre-deposited on support and then smaller molecules fill available space on the surface. Controlled ‘molecular printing” on the solid support with an appropriate mask or direct-write bottom-up deposition will be used to create sensing arrays with pre-designed patterns and properties.

90. Preserving kidney function during aging
Supervisor: Ursula Stochaj
University: McGill University (Montréal campus)
Location: Montreal, Québec
Start date: 2027-05-03 (flexible)
Disciplines: Biochemistry, Biological Sciences, Biology, Engg-Biological, Engg-Biomedical, Medical Sciences, Medicine, Microbiology, Molecular Biology, Pathology, Pharmacology, Physiology, Science Politique
SIGNIFICANCE. Organ functions decline during aging, and the most profound changes occur in the kidney. More than 50% of the elderly suffer from kidney dysfunction. This is significant, because the loss of kidney performance severely affects other organs and thereby overall health.
Worldwide, many human populations age. Therefore, new strategies to preserve kidney function in aging individuals are urgently needed.
BACKGROUND. Aging is the “continuous loss of physiological integrity”. This loss increases the probability of death. Kidney functions deteriorate during aging. Our project will address these important health problems by focusing on molecular chaperones. Molecular chaperones are proteins that participate in numerous cell functions. They are the first line of defense against kidney injury and cellular stress. Molecular chaperones are a critical support system that helps the kidney to survive the “stress of aging”. It is not understood why molecular chaperones fail when kidneys age.
HYPOTHESES. (1) We propose that molecular chaperones do not function properly in the aging kidney. This causes kidney failure in the elderly. (2) Pharmaceutical drugs can improve the actions of molecular chaperones and thereby prevent the loss of kidney performance during aging.
RESEARCH. Our studies will define the role of molecular chaperones for kidney aging. To achieve this, we developed model systems for kidney cells that recapitulate the hallmarks of aging. Using these models, we will define fundamental aspects of kidney cell aging.
EXPECTED OUTCOMES. The aging-related decline in kidney function has significant impact on human well-being. Despite the importance of molecular chaperones, little is known about their performance in the aging kidney. Our research project will begin to fill this gap. We expect to identify new avenues to prevent or slow down the loss of kidney function during aging. Ultimately, we will apply this knowledge to preserve kidney performance in the elderly.
Research area, student roles & skills

Supervisor: Alexander Baker
University: Dalhousie University (Halifax campus)
Location: Halifax, Nova Scotia
Start date: 2027-05-03 (flexible)
Disciplines: Biochemistry, Chemistry, Science and Technology, Molecular Biology
The expansion of non-canonical amino acids (ncAAs) has enabled solutions to challenges across therapeutics, bioconjugation, detecting protein-protein interactions, and cellular localization. This research project focuses in two areas, the first is the recombinant expression of proteins which includes; 1) enzymes and adhesive biomaterials, 2) the synthesis of novel ncAAs to incorporate or functionalize proteins and materials. We are focused on the incorporation of ncAAs to enable the controlled delivery of therapeutic proteins and use of enzymes for organic transformations. Functional groups which we are focused on introducing in the ncAAs include catechols, ketones, and oxyamines that can bind surfaces or react with other functional groups to form covalent bonds. Catechols are abundant in numerous marine adhesive proteins, and ketones and oxyamines can form dynamic and biocompatible covalent linkages. Proteins are expressed recombinantly in E. coli and purified using affinity chromatography. The chemical synthesis of ncAAs involves multi-step reactions and requires complete characterization of novel compounds with access to automated flash chromatography instrumentation, NMR spectroscopy, and mass spectrometry. We will measure the efficiency of protein expression with the synthesized ncAAs and subsequently assess conjugation to synthetic and natural biopolymers using optical assays. Specifically, cell-free protein expression will be used to evaluate ncAA incorporation using a DNA template encoding a reporter protein. The applicant will have the opportunity to engage in bacterial cell culture, protein expression, multistep organic synthesis, as well as explore bioorganic applications with synthesized non-canonical amino acids. This includes working with bacteria and proteins to evaluate protein biosynthesis.

93. Rescuing Mitochondrial Dysfunction in a Patient-derived Stem Cell Model of Parkinson's Disease
Parkinson disease (PD) is the second most prevalent neurodegenerative disease worldwide and the most common human movement disorder, affecting over 100 000 Canadians. Characterized by a progressive decline in voluntary movement, motor function eventually dissipates and patients lose the ability to both move and speak. The closest pathological correlate to loss of motor function is Lewy body formation, resulting from intercellular deposition of protein aggregates, the primary structural component of which is α-synuclein (α-syn). While many anatomical brain regions are affected in PD, dopaminergic (DA) neurons of the substantia nigra pars compacta are the first to shown signs of pathology. These cells are known to have high mitochondrial energy demands and, as a result, are particularly sensitive to mitochondrial stress. Utilizing a novel stem cell model of PD that allows for comparison of a disease causing A53T α-syn mutation against isogenic (genetically corrected) controls, this project will assess the endogenous role of α-syn in multiple aspects mitochondrial transport and energy/oxidation processes. Using patient derived human induced pluripotent stem cells we will first differentiate both the disease and genetically corrected control systems into DA neurons. We will then evaluate how mutation in α-syn impacts on mitochondrial transport, and membrane potential using high resolution live cell imaging coupled with biochemical analysis of mitochondrial machinery. These experiments will determine whether α-syn mutation perturbs mitochondrial transport and as a result, energy supply to the subcellular compartments that demand it. Students will gain skills in stem cell technology for disease modeling, mitochondrial metabolism and metabolic profiling (metabolomics) and live cell structured illumination based microscopy.
Research area, student roles & skills
Research area: My research focuses on stem cell based models of Parkinson’s disease and the effect of mitochondrial stress on the nervous system. We are attempting to understand the link between mitochondrial dysfunction, proteostasis and the transcriptional deficits that result in neurodegenerative disease. Additional research is focused on oxidative modification of proteins and their effect on synaptic plasticity, as well as, direct differentiation of stem cells to replenish damaged brain tissues. To this end, we are attempting to improve protocols to generate both oligodendrocyte and neuronal precursor cells to promote cell therapy after injury.

94. Role of DDX41 in Nuclear Speckle and MDS/AML
Supervisor: Yuliang Wu
University: University of Saskatchewan (Saskatoon campus)
Mutations in DDX41 (DEAD‑box helicase 41) cause myeloid neoplasms, including myelodysplastic syndromes (MDS) and acute myeloid leukemia (AML), with the missense mutation R525H observed in approximately 67% of affected patients. Despite its clinical significance, the molecular mechanisms underlying DDX41‑driven leukemogenesis remain incompletely understood. We recently found that DDX41 is required for activation of the cGAS–STING pathway for type I interferon production (Singh et al., Cell Reports, 2022) and DDX41 facilitates homologous recombination repair by resolving R‑loops (Aggarwal et al., Nucleic Acids Research, 2026). Dysregulation of these immune and genome‑maintenance pathways may contribute to the development of MDS and AML. In addition, our preliminary data indicated that DDX41 localizes to nuclear speckles (NSs). NSs are membraneless nuclear compartments that function as hubs for RNA‑processing factors, particularly those involved in pre‑mRNA splicing.
We hypothesize that DDX41 is required for the proper structure and function of NSs, and dysregulation of NS organization may contribute to the development of MDS and AML. To test this hypothesis, we will use DDX41 CRISPR knockout cell lines, with wild‑type cells serving as controls, and subject them to anisomycin treatment, a translation inhibitor that induces RNA‑processing stress. We will then assess NS integrity by examining two key NS markers, SON and SRRM2, at multiple levels: mRNA expression by quantitative PCR, protein abundance by Western blotting, subcellular localization by immunofluorescence (IF), and speckle dynamics by fluorescence recovery after photobleaching (FRAP). In parallel, we will evaluate the effects of disease‑associated mutations by analyzing DDX41‑knockout cells reconstituted with the DDX41‑R525H mutant, as well as primary blood and bone marrow samples from MDS/AML patients harboring the R525H mutation. These models will be used to determine how DDX41 mutations affect NS formation, composition, and dynamics under stress conditions, thereby linking altered NS regulation to DDX41‑driven myeloid pathogenesis.
Research area, student roles & skills
Research area: Cancer, biochemistry, cell biology, molecular biology, helicase
Student roles: The student will participate in this ongoing project and work directly with a graduate student in Dr. Wu’s lab.

These analyses will include mRNA expression by quantitative PCR, protein levels by Western blotting, subcellular localization by IF, and speckle dynamics by FRAP. In addition, the student will examine nuclear speckle formation under stress conditions in DDX41‑KO cells reconstituted with the DDX41‑R525H mutant, as well as in primary blood and bone marrow samples from MDS/AML patients harboring DDX41 mutations. The extent of the student’s involvement in these experiments will be tailored to their available time and progress over the course of the project.
The student will also interact with other researchers in the Cancer Research Cluster (https://research-groups.usask.ca/cancercluster/) and the Department of Biochemistry, Microbiology, and Immunology (https://medicine.usask.ca/bmi/index.php).

96. Rôle des microvésicules d'origine plaquettaires dans la modulation de cellules immunitaires
Platelets are small anucleated cells (about 3-5 µm) in discoid shape that patrol the vascular supply to prevent blood loss. Although these cells are better appreciated for their roles in blood clotting, more and more studies show that these cells are active participants in several types of inflammatory diseases, including PAR. Activation of platelets in response to various stimuli such as collagen, thrombin or immune complexes results in the generation of 3 sub-populations of microparticles (MPs). These subpopulations of platelet MPs are abundantly present in the synovial fluid once they have arrived in the synovial fluid, these MPs can secrete a panoply of inflammatory mediators but can also be internalized by the neutrophils present in the fluid. However, the consequences of the local generation of these inflammatory mediators derived from platelet MPs and the internalization of these in neutrophils remain very little known to date. Therefore, this project aims to better understand the role of MPs in the initiation and maintenance of inflammatory phases.
Research area, student roles & skills
Research area: I study the role of microparticles / microvesicles (size about 500 to 1000 nm) in inflammatory diseases, in particular in rheumatoid arthritis. Rheumatoid arthritis is a disease that affects approximately 1% of the North American population and is one of the leading causes of disability in Canada. So my laboratory studies the different inflammatory processes involved in this terrible disease using multiple approaches.

97. Screening for compounds effective against persisters in Mycobacterium tuberculosis
Supervisor: Neeraj Dhar
University: University of Saskatchewan (Saskatoon campus)
The lengthy regimens to treat TB are necessitated due to the ability of Mycobacterium tuberculosis to persist and survive against high concentrations of antibiotics. These surviving subpopulations of cells are referred to as persisters. The non-genetic nature and transient metastable state of persisters have made it challenging to study the mechanistic drivers of this phenomenon. Targeting this persisting subpopulation would greatly accelerate the treatment of TB and therefore lead to better control of the disease. Towards this aim, I propose to
1) design and construct phenotypic drug discovery screens targeting the hallmark features of persisting TB bacilli. This would involve genetically engineering reporter strains that would provide readouts on pathways utilised during persistence against antibiotics.
2) screen small-scale chemical libraries to identify compounds that specifically target the persisting subpopulations. We would use compound collections that have been procured from collaborators or sourced from commercial suppliers. We have also started screening ecological soil samples to screen for novel compounds exhibiting anti-persister activity.
3) confirm and validate the efficacy of the identified compounds in ex vivo models. Since M. tuberculosis is largely an intracellular pathogen, we shall be testing the efficacy of the identified lead compounds in ex vivo infection models such as macrophages and in organoid models. Considering the timeline of this fellowship, it would be difficult to carry out testing of this compounds in animal models, but promising compounds will be tested subsequently in animal models of TB infection.
Research area, student roles & skills
Research area: In 2020, approximately 10 million people developed Tuberculosis (TB) and 1.5 million lives were lost to the disease. This happens despite the fact that TB is curable and drugs targeting Mycobacterium tuberculosis (the causative agent of TB) have been around since the 1950s. A significant hindrance to TB control and eradication is the prolonged treatment regimen. Patients who develop TB are treated with 2-4 drugs over a period of 6 months. We need to identify new drug targets or approaches in order to accelerate the treatment of TB patients, by targeting the persisting M. tuberculosis sub-populations.
Student roles: Initially the student will be provided background material and literature related to the research. Then, the student will learn how to plan, design and conduct experiments effectively and how to analyze the data to draw meaningful conclusions. In terms of techniques, the student can expect to be trained in molecular biology, cloning, compound screening, assay design & antimicrobial discovery. Once the training period is completed, the student will initiate the project work independently under the immediate mentorship of a senior researcher in the lab. The student will be expected to design and execute the experiments independently and will be presenting the progress or discuss challenges during periodic presentations at lab meetings. During the stay in the lab, the student will not only get to learn the techniques being used in their own project but will be provided opportunities to acquire other techniques such as imaging, organoid culture, microfabrication etc that are used routinely in our lab. The aim is not only to generate data for this specific project proposed, but to provide a broad exposure to various techniques as well as to showcase the research environment and scientific enterprise. Towards the end of the project the student will provide a written project report including motivation, methodology & conclusions. If the results are significant and reproducible these will be included and written up to be part of a scientific manuscript that will be submitted for publication in peer-review journals with the student listed as an author.
Skills required: The project requires the student to have background biology knowledge. In terms of technical skills molecular biology skills (DNA isolation, cloning etc) and some microbiology skills (plating, transformation, pure culture etc) will be appreciated. The student should be familiar with online repositories for scientific articles and how to source relevant background literature for reading up on the project and to be updated with the recent developments in the field. Any quantitative programming skills (Matlab) or statistical analysis experience would also be useful.
98. Sensitive Cetrorelix Quantification by LC-MS from Cattle Milk
Supervisor: Haixia Zhang
University: University of Saskatchewan (Saskatoon campus)
Effective reproductive management is a cornerstone of profitability for both dairy and beef operations as improvements in pregnancy rates, calving time optimization, and genetic gain directly influence feed efficiency and lifetime productivity. However, only 15% of beef operations on Canadian prairies use artificial insemination (AI). Estradiol based AI protocols was banned in Canada due to regulatory concerns surrounding estrogen residues in food and the environment. As a result, Canadian dairy and beef producers must rely on GnRH and prostaglandin F2α based protocols that are safe but require more handling and show greater variability in response due to dependence on ovarian status at treatment initiation. Therefore, there is a long-standing need in Canadian beef and dairy industry for a new ovulation synchronization protocol that is as simple and effective as estradiol protocol is, but is steroid-free. Dr. Singh’s group (my collaborator) has been exploring the use of cetrorelix acetate (a 10-amino acid peptide), a GnRH antagonist, for estrus synchronization in cattle. The results indicated that this simple cetrorelix-based synchronization protocol is equally effective in heifers and suckling beef cows, and is a viable alternative to estradiol-based protocols.
However, cetrorelix is not approved by Health Canada for veterinary use in any species, including cattle. There are no established residue limits or food-safety evaluations in food-producing animals. The lack of information regarding cetrorelix residue in cattle tissues, blood, and milk is preventing the commercialization of a cetrorelix-based synchronization protocol on a global basis. In this project, a highly sensitive liquid chromatography-mass spectrometry (LC-MS) method will be developed to detect trace amount of cetrorelix and its metabolites in cattle milk. Cetrorelix will be spiked into the fresh cattle milk, and sample extraction will be optimized to remove lipids for effective drug extraction, and LC-MS will be used for its sensitive quantification.
Research area, student roles & skills

Real-time monitoring of food safety and quality is increasingly recognized as a critical strategy for protecting consumers, reducing food waste, minimizing economic losses, and enhancing consumer confidence in food products. Conventional quality assessment methods often rely on laboratory-based analyses that are time-consuming, destructive, and unsuitable for continuous monitoring throughout storage, transportation, and retail distribution. As a result, food quality deterioration may go undetected until products reach consumers.
Smart food packaging technologies have emerged as promising solutions to address these limitations. Among them, colorimetric sensor arrays offer significant advantages due to their low cost, ease of integration into packaging materials, rapid response, and ability to provide visual indications of quality changes without specialized instrumentation. By detecting chemical markers associated with food deterioration, these sensors can enable continuous, real-time monitoring of product freshness and safety.
This project aims to develop a smart packaging system based on colorimetric sensor array technology for monitoring the quality of high-value food products, particularly nuts and nut oils. These products are susceptible to oxidative degradation during storage, leading to the formation of off-flavors, loss of nutritional value, and reduced consumer acceptance. The proposed sensor array will be designed to detect volatile compounds generated during oxidation and translate these changes into distinct colorimetric patterns. Advanced data analysis methods will be employed to correlate sensor responses with product quality indicators and storage conditions.
The successful completion of this project will contribute to the development of next-generation smart packaging technologies capable of improving quality assurance, reducing food waste, and supporting the sustainable management of premium food products across the supply chain.

102. Stage-Specific Extracellular Vesicle Cargo in Plasmodium falciparum: Integrating Proteomics, Transcriptomics, and Lipidomics to Decode Parasite Communication
Plasmodium falciparum causes the most lethal form of human malaria, accounting for over 600,000 deaths annually. During its intraerythrocytic cycle, the parasite progresses through ring, trophozoite, and schizont stages, each with distinct metabolic activities and communication needs. Extracellular vesicles (EVs) — lipid bilayer-enclosed nanoparticles carrying proteins, lipids, and RNA — are now recognized as central mediators of cell-to-cell communication in malaria infections. Elevated EV levels correlate with disease severity, and EVs have been shown to modulate parasite invasion efficiency and trigger immune responses in the host.
Our laboratory has comprehensively characterized the proteomes of ring-, trophozoite-, and schizont-stage EVs, identifying over 800 proteins with striking stage-specificity (Opadokun & Rohrbach, 2024). Notably, we found that schizont-stage EVs are unexpectedly enriched in digestive vacuole proteins, suggesting a previously unrecognized organelle-to-vesicle trafficking pathway. We are now completing parallel transcriptomic and lipidomic datasets for the same stage-specific EV populations, using the Macdonald Mass Spectrometry Platform and RNA sequencing. These multi-omic datasets together will provide the first integrated molecular portrait of how EV identity is programmed across parasite development.
Students in this project will contribute to the completion and analysis of these datasets and to downstream functional validation. Key questions include: Do stage-specific EVs carry distinct RNA cargo (mRNAs, small RNAs) that could reprogram recipient cells? Does the lipid composition of EV membranes — which governs membrane curvature, fusogenicity, and receptor binding — change in stage-specific ways that reflect different biogenesis pathways? Can multi-omic integration reveal coordinated cargo signatures pointing to specific EV functions? Answers to these questions will fundamentally advance our understanding of how a single-celled parasite, hidden inside a red blood cell, communicates with its broader population and the human host.
Research area, student roles & skills
Research area: Extracellular vesicles (EVs) are membrane-enclosed nanoparticles secreted by virtually all cell types. In the human malaria parasite Plasmodium falciparum, EVs released from infected red blood cells mediate parasite-to-parasite and parasite-to-host communication and have been linked to disease severity, immune modulation, and transmission. Our laboratory has established leading expertise in P. falciparum EV isolation and characterization, generating stage-specific proteomic profiles across the intraerythrocytic cycle. We are now extending this work to transcriptomics (EV-associated RNA cargo) and lipidomics (EV membrane composition), building a multi-omic map of how EV identity and function change as the parasite develops.
Student roles: Both students will be fully integrated into the laboratory, each assigned a defined sub-project under direct supervision of a senior graduate student or postdoctoral fellow, with mentorship from Dr. Rohrbach. All laboratory training — including safety orientation and parasite culture — will be provided upon arrival. Student 1 will focus on EV RNA cargo. After learning P. falciparum culture (maintaining ring, trophozoite, and schizont-stage synchronized cultures using human RBCs from a licensed blood bank), this student will assist with EV isolation from stage-specific cultures using differential centrifugation and size-exclusion chromatography. The primary work will involve RNA extraction from EV preparations, quality assessment, and contribution to analysis of the stage-specific EV transcriptomic dataset currently being completed in the laboratory. The student will compare RNA profiles across parasite stages, identify candidate regulatory RNAs (e.g. small RNAs, parasite mRNA fragments), and contribute to data visualization and interpretation. Some functional work — testing whether EV-associated RNA can be delivered to recipient parasites — may also be initiated depending on progress. Student 2 will focus on EV lipidomics and membrane composition. This student will learn EV isolation and characterization (nanoparticle tracking analysis using the Particle Metrix ZetaView), then contribute to preparation and analysis of the lipidomic dataset being generated at the Macdonald Mass Spectrometry Platform. The student will examine differences in phospholipid, sphingolipid, and sterol profiles across stage-specific EV populations, and explore whether lipid compositional differences correlate with EV size distributions or known functional properties. Microscopy-based membrane labeling experiments to validate lipid raft-associated EV subpopulations may also be conducted. Both students will attend weekly lab meetings, keep detailed laboratory notebooks, present a final oral report, and submit a written project summary at the end of the internship.
Skills required: Students should have a background in cell biology, biochemistry, or molecular biology. Some familiarity with data analysis — spreadsheets, basic statistics, or bioinformatics — is an asset, as the project involves working with multi-omic datasets. Prior laboratory experience is helpful but not required; all technical skills will be taught. Curiosity about infectious disease biology and comfort working in a BSL-2 environment (full safety training provided) are essential. Students from life sciences, biochemistry, bioinformatics, or biomedical sciences programs are encouraged to apply.
103. Stem Celll Regeneration of damaged brain tissue after stroke
Transplantation of functionally-relevant donor stem-cell derived neurons and/or glia into hippocal slices and later rodents cerebral ischemia. Using novel approaches to generate hNSCs that are resistant to apoptotic cell death and pre-programmed to become neurons or glia, we will transplant hNSC-derived neuronal and glial progenitors into rodent models of focal cerebral ischemia induced by oxygen glucose deprivation or the intraluminal filament model of occlusion with subsequent reperfusion. Techniques for neuronal and glial differentiation using small molecules under defined culture conditions, appropriate for clinical use, are developed and in use in our laboratory. The challenge will be to not only promote the engraftment of cells that will develop into mature neurons in vivo, but also to promote survival of these new neurons. Along these lines, we have determined expression of MEF2C and NRF2 elicits a neuronal phenotype in 99+% of NSCs, are resistant to apoptosis, and resistant to oxidative stress. Similar approaches will be used for fostering glial (astrocyte, oligodendrocyte) lineages as well while avoiding apoptotic injury. It is anticipated that these cell-based and/or small molecule therapies will lead to future regenerative medicine approaches in humans.
Research area, student roles & skills
Research area: My research focuses on stem cell based models of neurodegenerative disease and how to repopulate the brain after injury. We are attempting to understand the link oxidative stress and tissue loss following stroke, and how we can use neural stem cells to regenerate the damaged tissue regions. To this end, we are attempting to improve protocols to generate both neuronal precursor cells and neurons for transplantation promote cell therapy after injury.

Cancer cells have drastically altered cellular signaling compared to healthy cells which often arrise due to changes in protein and nucleic acid expression or mutations. These changes in cell signaling lead to increase proliferation, cell motility and invasion. Cellular signaling is carried out by a very diverse group of molecules with can sense the levels of different molecules inside and outside the cell and transmit this information to various cellular processes, such as transcription factors, epigenetic regulators, cytoskeletal remodeler, etc.
We are interested in the molecular details of this signal integration and computation by protein and nucleic acid. We study two broad categories of molecules:
1. Rho activators
Rho GTPases are a family of proteins that regulate the cytoskeleton. Due to their role in cell shape and movement, their activity is often increased in metastatic cells. This increase in Rho activity is often tied to hyperactivation of their upstream regulators, the RhoGEF family of protein. We aim to better understand the normal function of RhoGEF in the regulation of Rho activity and how these functions are altered in cancer cells.
2. Long non-coding RNAs
LncRNAs are a family of large RNAs which are expressed, often at low levels, in a variety of cell types and accomplish a broad range of functions. Intriguingly, select lncRNAs have been proposed to interact directly with the signaling machinery and mediate changes in growth factors signaling, cytoskeletal remodeling and protein homeostasis. We plan on applying biochemical and structural characterization techniques to understand if lncRNAs are indeed acting as scaffolds for protein in cell signaling, and how their - often conserved - structure helps them carry out these functions.
Research area, student roles & skills
Research area: Our lab is interested cellular signaling and how it can be disrupted in cancer cells. We are looking to use structural biology techniques, such as cryo-electron microscopy, as well as other biochemical tools to study protein and nucleic acid complexes involved in cellular signaling. In particular, we will be looking at different classes of molecule involved in this process: (i) multi-domain proteins regulating Rho signaling (ii) Long non-coding RNAs with auxiliary roles in growth factor signaling.
Student roles: Based on their scientific interest, the student will be assigned to a specific project, centering on one lncRNA, or one activator of Rho GTPases. For this project the student will be tasked to identify interactors the molecule of interest, purify the molecule for structural characterization and to measure the strength of these interactions in a reconstituted system. If structural determination efforts are successful, functional assays to confirm structure findings will be carried out in a relevant model cell type (e.g. cancer cell lines). Structure determination will be accomplished mainly via cryo-electron microscopy, assisted by other techniques such as SAXS, MALS, NMR or crystallography. The student will be supervised directly by the principal investigator (Malik Chaker-Margot) who will help them develop the skills needed to accomplish the project.
Skills required: We expect the student to have training in biochemistry and molecular biology, including laboratory experience, either through university classes or hands-on academic lab experience. The student ought to know how to use a micropipette, prepare chemical solutions, and have basic knowledge of nucleic acid and protein purification methods. Any prior experience on structural biology or biophysical techniques, such as electron microscopy, crystallography, biological molecule NMR, light scattering or calorimetry would be seen as a major asset. Cell culture will also be a significant component of the project so prior knowledge would be valued.
105. Structure-Function Analysis of Cholesterol-Transport ABC Proteins
BACKGROUND: The transporter ATP-binding cassette (ABC) proteins play critical roles in regulating lipid metabolism and cholesterol homeostasis in higher eukaryotes. Deficiencies of these ABC transporters in humans can cause dyslipidemia that is associated with health conditions such as atherosclerosis, diabetes, fatty liver disease, and neurodegeneration. The physiological roles of ABC cholesterol transporters have been implicated in mediating cholesterol efflux for reverse cholesterol transport and in maintaining membrane integrity for cell survival. The mechanism of transporter-mediated cholesterol trafficking remains understudied. To understand the structural basis of the cholesterol-transport mechanism, we investigate atomic models of human sterol transporters by structural biology methods and using ABCG cholesterol transporter as a model system. ABCG transporter structures reveal a unique configuration for the membrane-embedded domain and its interaction with other parts of the protein. Using this model as the molecular framework, our research will biochemically characterize the mechanism of ABC protein-mediated cholesterol transport on cellular membranes and analyze the effects of disease-causing mutations. OBJECTIVES: The primary goal of this project is to study the molecular mechanism of ABC cholesterol transporters. The objectives during the internship include one of the following: (1) engineering of recombinant proteins, (2) isolation and purification of recombinant membrane proteins, (3) in vitro enzymatic assays, (4) in silico simulations, and (5) survey and assessment of recent publications. EXPECTED OUTCOMES: (A) We expect students to gain knowledge and learn skills on how to study the structure-function relationship of membrane proteins. (B) We expect to obtain new data and facilitate our research objectives. (C) We expect students to develop good communication skills in science.
Research area, student roles & skills
Research area: Our research concerns the critical biological question of what controls the lipid shuttling process to timely exchange across the lipid bilayers and to precisely respond to the systemic level of lipids. Specifically, my laboratory is directed at elucidating the molecular view of protein-mediated lipid trafficking on the cellular membranes, with emphasis on the membrane-anchored cholesterol and phospholipid transporters. Our team analyzes their function-structure relationship by building molecular models at atomic or near-atomic resolution using membrane protein structural biology and by understanding the chemical basis of lipid transport using protein biochemistry and biophysics.
Student roles: The student is expected to be present in the laboratory daily (normally 9 AM to 5 PM) to receive technical and theoretical training. Following appropriate training, the student will carry out wet-lab tasks relating to protein purification and characterization in addition to various dry-lab tasks, including experimental planning, data analysis, protein sequence alignments, and other bioinformatics methodologies. The student will be supervised and trained by senior lab personnel on biochemical methodologies, including SDS-PAGE, Western Blotting and large-scale human membrane-protein expression using a Pichia pastoris yeast expression system. The student will be expected to take detailed notes during training sessions and ask appropriate questions in order to prepare themselves to subsequently perform newly learned tasks independently. The student will be expected to participate in weekly group meeting (both journal club and work-in-progress), to compile data and generate figures, and to learn writing publication-quality reports. The student will experience a collaborative and educational environment that will support their development as a trainee and help prepare them for their future careers.
Skills required: A background in molecular biology, structural biology, biochemistry, biophysics, organic chemistry, and well-developed analysis skills is desirable. Strong written and oral communication skills in English are necessary. The student should be self-directed and enthusiastic to learn new skills and methodologies, such as computer-based bioinformatics and structural biology data analysis.
106. Surface Optimization of Graphene Field-Effect Biosensors
This project focuses on graphene field-effect transistors (GFETs), which are miniaturized on-chip electronic devices functionalized with biological receptors, such as antibodies or oligonucleotides, to selectively capture target biomolecules. In these sensors, biomolecular binding events are directly transduced into measurable changes in electrical conductivity, eliminating the need for optical detection and enabling compact, highly sensitive platforms.
A critical challenge lies in achieving precise control over the surface chemistry of graphene, particularly the density, distribution, and orientation of immobilized biomolecules, which strongly influence sensor performance, signal amplitude, and reproducibility.
The objective of this project is to systematically compare different surface functionalization strategies for immobilizing single-stranded DNA probes used in the detection of genetic biomarkers. The study will focus on two main approaches: non-covalent functionalization based on pyrene derivatives, which preserve graphene’s electronic properties, and covalent functionalization using aryldiazonium chemistry, which offers robust anchoring at the expense of potential electronic perturbations.
The student will fabricate and test various molecular assemblies and evaluate their performance using electrical measurements, complemented by microscopy and/or spectroscopy when appropriate. By correlating surface chemistry with device response, the project aims to identify optimal protocols for achieving controlled and reproducible biofunctionalization. These findings will contribute to the development of GFET-based biosensors for applications in precision diagnostics and personalized medicine.
Research area, student roles & skills
Research area: Our laboratory develops nanoscale electronic circuits based on low-dimensional materials functionalized with biological macromolecules such as nucleic acids and proteins. Due to their strong confinement, these nanomaterials exhibit exceptional sensitivity to their local environment, enabling the detection of tiny changes in molecular composition and organization at their surface. Our research aims to leverage this sensitivity to investigate biomolecular interactions across previously inaccessible spatial and temporal scales. Ultimately, we seek to translate these insights into innovative biomedical sensing technologies, with a particular emphasis on applications in oncology and precision medicine.
Student roles: The student will first be trained in the fabrication of graphene-based nanosensors using micro- and nanofabrication techniques, as well as in their electrical characterization in liquid environments using specialized instrumentation developed in our laboratory.
The core of the project will involve the functionalization of GFET devices with single-stranded DNA probes using a variety of chemical anchoring strategies. The student will implement different surface chemistry protocols, carefully control experimental conditions, and document each functionalization process.
The student will then perform electrical measurements to evaluate sensor response before and after biomolecular immobilization, and upon exposure to target analytes. These experiments may be complemented by characterization techniques such as optical microscopy, atomic force microscopy, or Raman spectroscopy, depending on project progression.
A key component of the role involves data analysis and interpretation. The student will compare experimental results across different functionalization strategies, identify trends, and relate observations to physical models of charge transport and surface interactions in graphene.
Throughout the internship, the student will maintain a detailed laboratory notebook, participate in group meetings, and receive regular mentorship from senior researchers. At the end of the project, the student will prepare a written report and present their findings to the research group and the broader institute community, gaining valuable experience in scientific communication.
Skills required: Our multidisciplinary team welcomes students from physics, biomedical engineering, chemistry, or molecular biology. Prior laboratory experience is an asset, including exposure to electrical measurements, microscopy or spectroscopy techniques, or wet chemistry; however, no specific technical expertise is required, as training will be provided. We value strong analytical thinking, attention to detail, creativity in problem-solving, and the ability to work both independently and collaboratively. Motivation, curiosity, and good communication skills are essential for successfully conducting interdisciplinary research in a dynamic laboratory environment.
107. Survival Secrets: Unraveling how food pathogens adapt to environmental stressors
Food-borne diseases are a major threat for public health and incur significant economic losses. For instance, around 80.3 million cases of salmonellosis worldwide are annually linked to the consumption of contaminated food products. But what makes food pathogens so successful?
Their success can be attributed to their remarkable genetic diversity as well as capability to adapt and survive during harsh environmental conditions such as starvation, heat, low moisture, low pH, or even disinfectants.
The goal of this study is to expose food pathogens such as Salmonella, Escherichia or Listeria to different stressful conditions and investigate their survival rates as well as molecular adaptations using proteomics, transcriptomics or metabolomic methodologies. Since bacterial cells might undergo structural changes, we will complement our study with microscopic analyses.
Research area, student roles & skills
Research area: My research interests are mainly centered on the system biological understanding of pathogens and their interactions. Analytical advances have made it possible to create huge molecular data sets. However, this data complexity has posed a challenge for the biological interpretation. Moreover, the components in biological systems are connected through a web of interactions which are not easily accessible to traditional molecular biological methodologies. In my line of work I use high-throughput technologies to create models of these networks and use them to identify key nodes of cellular processes, pathogenic interactions or disease pathways.
Student roles: The candidate will learn to cultivate food pathogens and expose them to different challenging environmental conditions including desiccation, heat or nutrient stress or antimicrobial substances. Subsequently, the candidate will determine survival rates. Since morphological adaptions might be expected, we will complement this study with microscopical analyses. In addition, global molecular analyses such as proteomics or metabolomics can be conducted to explore the mechanisms of adaptation or tolerance on a more detailed level.
Skills required: Ideally the student will have a background or interest in microbiology, biotechnology and/or molecular biology. Having participated in a practical course involving aseptic and/or molecular biological techniques would be an asset. At minimum the student should have knowledge of laboratory safety standards, though specific training will be offered on-site.
108. Susceptibility to posttraumatic disorders: towards a personalized medicine in psychiatry
Supervisor: Jessica Deslauriers
University: Université Laval (Québec campus)
Location: Québec, Québec
Start date: 2027-05-03 (flexible)
Disciplines: Biochemistry, Biological Sciences, Health Studies, Immunology, Medical Sciences, Molecular Biology, Neuroscience, Pharmacology, Physiology, Psychology
Une meilleure compréhension des mécanismes contribuant à la vulnérabilité au trauma psychologique est cruciale pour développer de nouvelles avenues prophylactiques et
thérapeutiques. Les vétérans ayant reçu un diagnostic de TSPT sont plus à risque de développer une hypertension que ceux qui ne sont pas atteints de TSPT. De plus, l’inflammation chronique est observée à la fois dans la physiopathologie de l’hypertension et celle du TSPT, suggérant des mécanismes inflammatoires communs entre les deux pathologies. Cependant, la relation entre l’inflammation, la pression artérielle et le TSPT demeure incomprise. Il y a aussi un besoin urgent de cibler des biomarqueurs permettant l’identification des individus « à haut risque ». Récemment, l’intérêt des exosomes dérivés du cerveau (EDCs), traversant la barrière hémato-encéphalique (BHE) pour se retrouver dans le sang, a émergé. En effet, ces EDCs mesurables de manière accessible dans le plasma peuvent constituer un puissant outil pour développer des biomarqueurs associés au risque de TSPT.
Objectifs et méthodologie: Le projet proposé vise à identifier des biomarqueurs plasmatiques et cérébraux de vulnérabilité au trauma psychologique, avec un premier focus sur la pression artérielle, l’inflammation, l’intégrité de la BHE et les EDCs chez la souris. Avec notre modèle unique de stress de prédation, les comportements anxieux et d’évitement seront mesurés afin de séparer les souris exposées au stress de prédation en deux groupes : « résilient » vs. « vulnérable ». Les marqueurs inflammatoires/EDCs, ainsi que des marqueurs de la BHE et la pression artérielle seront mesurés dans le sang et dans les tissus du cerveau à plusieurs temps avant et après l’exposition au stress de prédation. Le projet permettra ainsi de (1) déterminer l’association entre la réponse immunitaire, l’intégrité de la BHE et la vulnérabilité au trauma psychologique; et (2) d’identifier des biomarqueurs sanguins qui permettraient de prédire précocement les individus à risque.
Research area, student roles & skills
Research area: Jusqu’à 90% des individus font face à un évènement traumatique au cours de leur vie, et plus de la moitié d’entre eux développent un trouble psychiatrique, tels que le TSPT. Les traitements ayant une efficacité très limitée, il y a un besoin criant de développer de nouvelles interventions pharmacologiques. Notre laboratoire utilise des approches multidisciplinaires pour (1) comprendre les mécanismes inflammatoires impliqués dans la vulnérabilité au trauma psychologique; (2) identifier des biomarqueurs prédisant une vulnérabilité; et (3) utiliser une pharmacothérapie de précision en ciblant des interventions adaptées aux caractéristiques pathophysiologiques des
patients et individus à « haut risque psychiatrique ».
Student roles: Dans le cadre de sa participation au projet de recherche au sein d’une équipe dynamique, vous serez appelé.e à évaluer le phénotype comportemental chez la souris, mesurer la pression artérielle et collecter des échantillons de sang et de tissus de cerveau. Vous aurez aussi l’opportunité d’apprendre ou utiliser des techniques de biologie moléculaire (immunohistochimie, immunobuvardage, ELISA, PCR, etc), à appliquer les analyses statistiques pertinentes et interpréter les résultats avec une approche critique.
Skills required: L’étudiant.e doit poursuivre des études de 1er cycle (baccalauréat, ou équivalent) dans un domaine pertinent à la recherche : pharmacie, biologie moléculaire, sciences biomédicales, biochimie ou toute autre discipline connexe. La motivation, la capacité de travailler en équipe ainsi que la capacité d’analyse critique sont des compétences requises. Une expérience en manipulation des souris et/ou techniques de biologie moléculaire est un atout.
109. Synthesis of bioactive carbohydrates using cell-free synthetic biology
Supervisor: David Kwan
University: Concordia University (Montréal campus)
Carbohydrates, also referred to as glycans, are among Nature's most abundant biologically active molecules. These compounds consist of combinations of sugar residues assembled into specific structures. Beyond the familiar structural polysaccharides such as cellulose or chitin, and energy storage molecules such as glycogen or starch, carbohydrates play a wide range of roles in biology. Oligosaccharides (glycans consisting of two to ten sugar units) frequently function as information-bearing molecules, often found on proteins and on cell surfaces, that play a critical role in many biological processes such as cell–cell recognition, ligand–receptor binding, and cell signaling. Furthermore, glycosylation (attachment of sugar residues) is also important in the biological activity of many pharmaceutically-active compounds that are used in medicine.
Isolation of bioactive glycan molecules from natural sources alone often yield insufficient quantities for study or for their development as therapeutics, thus efficient means to synthesize these compounds are needed. The structural diversity that gives rise to their wide spectrum of biological activities poses a difficult challenge for the synthesis of glycans by conventional chemical organic syntheses. However, using enzymes to assemble these molecules is an attractive alternative to classical chemical methods since these enzymes have evolved to synthesize very specific structures. A remaining challenge with this approach is that the glycosyltransferase enzymes typically used require nucleotide sugars as substrates and these are relatively expensive since they are metabolic intermediates typically isolated from microorganisms. This limits the scale of economically feasible enzymatic synthesis. In this research project, we will develop a cell-free synthetic biology approach to engineer an enzyme pathway for generating and recycling the nucleotide sugar substrates for glycosyltransferase enzymes from cheaply available cellulose. Development of an in vitro metabolic pathway to supply glycosyltransferase substrates will allow our enzymatic approaches to glycan synthesis to be economically scaled up.
Research area, student roles & skills
Research area: Our research group specializes in chemical and synthetic biology, focusing on the function and engineering of enzymes. We have a particular interest in carbohydrate processing enzymes and have devoted research towards their development as biochemical tools and as targets for novel molecular therapeutics. We employ synthetic biology, both through the metabolic engineering of micro-organisms, and by constructing cell-free enzymatic pathways to produce valuable molecules, including bioactive glycosides and carbohydrates.
Student roles: In the course of the internship, the student will clone genes for multiple enzymes in a designed pathway using recombinant DNA techniques. Cloning of these enzymes will be followed by recombinant protein expression in E. coli, and the enzymes will then be purified using chromatographic techniques. Enzymes will then be tested for their activity using assays that will be developed in the course of the internship, and which will generally involve methods including spectrophotometry, thin-layer chromatography, mass spectroscopy, and potentially HPLC and NMR techniques. Assembled enzymatic pathways or parts thereof will then be tested towards the synthesis of bioactive carbohydrates. Laboratory-scale enzymatic syntheses of these glycans will be carried out and products will be isolated and purified by chromatographic techniques so that synthesized glycans can be quantified to determine the efficiency of the developed processes. The student will also actively review published literature and research towards the development of the research plan and strategy. He or she will participate in research discussions and meetings and may have the opportunity to take part in a research symposium or conference. The student will be expected to provide periodic written research updates and will write a final report upon the completion of the internship.
Skills required: The candidate for the research internship will ideally be a student in molecular biology, biochemistry, chemistry, or a related discipline. He or she will have practical laboratory experience in standard molecular biology techniques and will ideally have experience with recombinant DNA techniques, molecular cloning, protein biochemistry, and performing enzyme assays. Background in carbohydrate biochemistry and glycobiology will be considered an asset. The intern should be comfortable with reading scientific literature on the topic, developing protocols, and effectively communicating scientific results in both spoken and written communication.
110. Synthetic (glyco)biology approaches to modify biological membranes for improved cell therapies
Supervisor: David Kwan
University: Concordia University (Montréal campus)
Sugars coat the cells of each and every living organism. The macromolecules made up of sugar building-blocks—referred to as carbohydrates or glycans—are diverse in their structures and can be linked to proteins or lipids on cell surfaces. Cell-surface glycans make up an important mode of intercellular communication; playing key roles in cell recognition, cell signaling, and cell-cell interactions. Cells also communicate with one another using extracellular vesicles—called exosomes—and these too are covered with distinct patterns of glycans. Both stem cells and exosomes make up important biologic therapies that are anticipated to revolutionize medicine in the 21st century. The effectiveness of such treatments depends upon targeted delivery of these biologics to the tissues where they are required, where stem cells will differentiate into specific desired cell types or where exosomes will release their cargo (e.g. therapeutic genes or drugs). The glycans displayed on stem cells and exosomes plays a large part in this targeted delivery through interactions with specific receptors.
Using synthetic biology approaches to manipulate the glycan structures on biological membranes, we aim to develop methods to improve stem cell- and exosome-based therapies for regenerative medicine and gene transfer for the treatment of immune disorders, metabolic disorders, and cancers. By tuning and manipulating the carbohydrate signals on stem cells and exosomes, we can improve the efficacy of their therapeutic delivery. Drawing on our lab’s expertise in enzymology, glycobiology, and carbohydrate chemistry we are currently pursuing a research program addressing this challenge by focusing on three objectives:
1) Develop methods for producing defined glycan structures using enzymatic biocatalysis
2) Apply simple chemical approaches to modify cells/exosomes with these glycan structures
3) Investigate the effects of glycan modifications on stem cell or exosome interactions
Research area, student roles & skills
Research area: Our research group specializes in chemical and synthetic biology, focusing on the function and engineering of enzymes. We have a particular interest in carbohydrate processing enzymes and have devoted research towards their development as biochemical tools and as targets for novel molecular therapeutics. We employ synthetic biology, both through the metabolic engineering of micro-organisms, and by constructing cell-free enzymatic pathways to produce valuable molecules, including bioactive glycosides and carbohydrates.
Student roles: In this project the Mitacs Globalink Research Intern will produce and test several cell and exosome surface-modifying reagents.
In vitro enzymatic synthesis of glycoconjugates. Our research group has cloned the genes from several bacteria that are involved in the assembly of specific glycan structures—many of which are also found on human cell surfaces. The Research Intern will express and purify these recombinant enzymes from E. coli and use them as biocatalytic tools to produce a variety of glycan structures (glycoconjugates) attached to a chemical linker bearing an azide functionality that will facilitate their attachment onto biological membranes.
Decoration of biological membranes with synthetic glycans. Working with our collaborators in the labs of Dr. René Bazin and Dr. Lionel Loubaki at Héma-Québec (the province’s blood services and biologics provider), and Dr. Christopher Brett at Concordia University, the Research Intern will develop methods to covalently attach the synthetic glycoconjugates to stem cell and exosome surfaces through chemical adaptor molecules that specifically react with the azide groups of the glycoconjugates and lysine residues of membrane proteins on stem cell or exosome surfaces.
Probing interactions of glycan-modified membranes. In continued collaboration, the Research Intern will perform experiments to determine the biological effect of glycan modification on these surfaces. The binding interactions of modified stem cells with specific receptors will be assayed in vitro using techniques established by our collaborators at Héma-Québec and the effect of glycan modification of exosomes will be investigated in Dr. Brett’s research group.
The Mitacs Globalink Research Intern will join a motivated, multidisciplinary team of scientists applying chemical and synthetic biology approaches to develop innovative solutions to improve health and deliver benefits to society. He or she will receive first-class training at the Centre for Applied Synthetic Biology which houses Canada’s first and only Genome Foundry.
Skills required: The ideal candidate for this research internship will be a student in molecular biology, biochemistry, chemistry, or a related discipline. He or she will have practical laboratory experience in standard molecular biology techniques and will ideally have experience with recombinant DNA techniques, bacterial culture, protein biochemistry (particularly expression and purification of recombinant proteins), and performing enzyme assays. Background in carbohydrate biochemistry and glycobiology will be considered an asset. The candidate should be comfortable reading scientific literature on the topic, developing protocols, and effectively communicating scientific results in both spoken and written communication.
111. Synthetic Biology for Metabolic Engineering of Chemicals from Biomass-based Feedstocks
Further, increased volatility in the petrochemical feedstocks has necessitated a paradigm shift towards the use of biomass based feedstocks for the synthesis of transportation fuels. Consequently, there have been intense academic and corporate research efforts for the design of microbial strains for the production of ethanol, butanol, fatty acid methyl esters and isoprenoids as biofuels. In contrast, there have been very few instances of microbial strain engineering for large-scale commodity chemicals with the exception of 1,3 propanediol (DuPont), lactic acid (Cargill), and 1,4 butanediol (Genomatica). A common feature among all of these chemicals is that they are derived primarily from central metabolism. The success of these efforts clearly motivates the microbial strain engineering efforts for other chemicals which are further removed from central metabolism.
Recently, the U.S. Department of Energy identified a dozen chemicals with large market demands globally and in North America that could be potentially synthesized from biomass-based feedstocks. These include dicarboxylic acids such as succinic, malic, fumaric, itaconic and adipic acids as well as levulinic acid. In the case of chemicals that are derived from central metabolism such as succinic acid, malic and fumaric acid, metabolic pathways and enzymes for their synthesis are found in typical industrially used hosts such as Escherichia coli and Saccharomyces cerevisiae. However, there still remains the challenge of engineering the metabolism of the microbial host so that volumetric productivity, titer, and product yield can be improved for economic viability. In contrast, for chemicals such as adipic acid, the synthesis pathways are not present in typical industrial hosts resulting in an additional challenge for strain engineering. One of the challenges to developing bioconversion technologies for the production of biochemicals is attaining high conversion efficiency from variable sugar streams. A primary goal is to use systems biology methods to design strains.
Research area, student roles & skills
Research area: In the recent years, global and national policies have been increasingly dominated by issues relating to energy security and environmental health. These concerns have clearly highlighted the importance of sustainable development technologies that will be required to meet the growing global energy demand without compromising the health of the environment. Key technologies that are being emphasized at the national and international level are biorefinery processes to synthesize renewable fuels and high-value co-products from biomass. There is a need to develop sustainable bioprocesses that can be used to synthesize fuels and chemicals. While there has been significant attention and emphasis in
Student roles: In this project, the student will learn the basics of systems biology starting with exposure to metabolic network reconstruction, and bioinformatics. This initial step will be followed by learning the essentials of mathematical models of metabolic networks. The student will then use optimization algorithms to design new strain strategies for chemicals production. He will then construct the strains and characterize the performance of the strains and prioritize the best candidates for strain optimization. The student will also use advanced synthetic biology techniques like the dynamic controller developed in our lab to control metabolic pathways for improving productivity.
Skills required: Student should be trained in engineering (e.g., chemical or biochemical engineering) with basic knowledge of biochemistry. He should also know the basics of mathematical modeling and being able to program in MATLAB or Fortran is a plus. Knowledge of bioinformatics is a major plus. Basic experimental skills and interest in learning molecular biology and analytical chemistry tools and other advanced synthetic biology techniques will be a plus.
112. Systems biology approaches to study interbacterial interactions
Projects in the lab use high-throughput approaches, including systems biology and functional genomics, to study the metabolism and physiology of bacteria in contexts that are relevant during infections. Our goal is to define novel potential targets that could help the development of novel antimicrobial strategies. In particular, we are interested in understanding interbacterial interactions, for instance between bacterial pathogens and bacteria from the microbiota. We use single-gene deletion collections to define genes that are essentials during these interactions. We believe that theses genes represent possible targets and will be useful to design novel antimicrobial strategies. Our model organisms are Escherichia coli, Salmonella Typhimurium and Pseudomonas aeruginosa. During this project, the selected intern will be in charge of confirming and characterizing some genetic interactions from our high-throughput screens. The exact project will be defined in collaboration with the selected intern according to his/her interests and skills.
Research area, student roles & skills
Research area: Resistance to antibiotics as reached crisis proportion. This situation is the result of two main problems. On one side, bacteria are becoming increasingly resistant to current antibiotics, to the point that we now see bacteria that are resistant to all current antibiotics. On the other hand, no novel class of antibiotics have been discovered in the last 30 years, and our pipeline of novel compounds is extremely limited. Therefore, novel approaches are needed to identify novel antimicrobial targets and to develop the next-generation of antibiotic strategies.
Student roles: The student will be in charge of his/her own projet, from reading the literature to performing the experiments and analyzing the results. Furthermore, the students will be responsible (with other members of the laboratory) of lab chores to make sure the lab function properly.
Skills required: Our lab seeks motivated students with an interest and experience in microbiology, bacterial genetics, bioinformatic, or something similar. Students should be able to work independently and posses good organizational skills and scientific curiosity. Understanding French is an advantage.

Supervisor: Taha Azad
University: Université de Sherbrooke
Location: Sherbrooke (Québec), Québec
Start date: 2027-05-07 (flexible)
Disciplines: Biochemistry, Biological Sciences, Biology, Health Studies, Immunology
High-grade brain tumors such as glioblastoma remain extremely difficult to treat due to limited therapeutic options and the presence of an immunosuppressive tumor microenvironment. This project aims to develop next-generation RNA-based immunotherapies that can activate anti-tumor immunity directly within brain tumors.
Under the supervision of Dr. Taha Azad, the student will design and generate self-amplifying RNA (saRNA) constructs encoding immune-stimulating molecules such as pro-inflammatory cytokines (e.g., IL-12, IFN-β) or immune checkpoint modulators. These constructs will be delivered using lipid nanoparticles (LNPs), with a focus on achieving efficient expression in glioma cells.
The project will begin with in vitro studies using established glioma cell lines. The student will evaluate transfection efficiency, RNA expression levels, and downstream immune-related signaling. Functional assays will include measurements of cell viability, apoptosis, and cytokine production. The student may also explore how these constructs influence tumor cell sensitivity to immune-mediated killing.
This project provides hands-on training in RNA design and synthesis, nanoparticle-mediated delivery, cell culture, and molecular assays. It offers a strong foundation in cancer immunotherapy and RNA therapeutics, with clear potential for downstream translational development.

114. Targeting RET kinase contributions to human cancer
Supervisor: Lois Mulligan
University: Queen's University (Kingston campus)
Location: Kingston, Ontario
Start date: 2027-05-31 (flexible)
Disciplines: Biochemistry, Biological Sciences, Biology, Genetics, Health Studies, Molecular Biology, Neuroscience, Pathology, Medical Sciences
Tumour metastasis is the primary cause of cancer related death, worldwide. Our lab focuses on the regulation of the RET receptor, a cell surface molecule with roles in growth and metastatic spread of several clinically challenging human cancers including neuroendocrine, pancreatic, lung and breast tumours. While we know that RET is abnormally active in these cancers, we don’t fully understand how it escapes normal regulatory controls to contribute to the spread of these devastating diseases. Our goals are to characterize these regulatory processes and explore RET’s roles and potential as a therapeutic target in human cancers. We are doing this using high throughput approaches, such as Bio-ID or synthetic lethal screens, to identify RET interactions with regulatory molecules, and investigating the effects of these specific regulators on RET functions and signals that allow RET to escape normal controls and contribute to cancer.
The student will contribute to our investigations of protein interactions that regulate RET expression and signaling at the cell surface and investigate how these can promote cancer cell invasiveness. Students may perform molecular analyses of protein expression and interactions in vitro (western blotting), and in vivo (immunofluorescence microscopy). We will be exploring effects of perturbing expression of RET or other invasion-associated signaling molecules (over expression, shRNA knockdown or CRISPR knockout) on RET-mediated tumour cell growth or invasion in a variety of functional assays such as proliferation, viability or migration assays. These studies will allow us to explore therapeutic opportunities to block these processes by identifying and exploring novel molecular targets for controlling RET–mediated cell motility and invasion as approaches to limiting RET’s cancer-causing activities.
Research area, student roles & skills
Research area: Cells require many different signals from their surroundings to grow, move, or survive. These processes are essential for normal development, but can be hijacked in cancer cells, allowing the disease to spread. Our lab focuses on a cell surface receptor called RET that conveys extracellular signals in many tissues. However, in some cancers, RET signals cause the tumour to grow or help it spread throughout the body making the disease hard to treat. My lab uses molecular, cell biology and high throughput approaches to explore RET’s cellular roles in order to develop tools for targeting these processes in human cancer.
Student roles: The student will have opportunities to participate in a variety of approaches as part of the work described. They will apply the skills developed in their undergraduate courses to help analyse existing data to identify novel RET protein interactions with regulatory proteins of interest. Together with the supervisor, the student will develop a research plan to functionally explore these interactions and their contributions to cancer. The student will address these goals using an array of approaches. Standard methodologies including molecular and cellular biology, protein and/or DNA manipulation, and mammalian cell culture will be used throughout and some experience with these methods would be an asset. The student will perfect their skills in fundamental techniques used in biomedical research such as protein isolation, immunoblotting, immunofluorescence microscopy and cell-based functional assays (migration, invasion, proliferation and/or viability). As time permits, the student will have opportunities to acquire skills in state-of-the-art methodologies including real time gene expression analysis, CRISPR-Cas9-mediated gene knockout or shRNA knockdown, whole cell imaging of live and fixed cells by confocal microscopy and quantitative image analysis. Motivated students are encouraged to further build communication skills through preparation of their work for presentation and publication. The student will work within a small and very collegial group of graduate and undergraduate students and research associates under the supervisor’s direction. Our research group is part of the Division of Cancer Biology and Genetics at the Sinclair Cancer Research Institute at Queen’s University, which includes 12 Principal Investigators and over 60 students and fellows with complementary interests and expertise in a broad range of cancer research areas. The interested student will have opportunities to interact with members of multiple laboratories with different perspectives and expertise that will help to expand their professional research network and enhance their research experience.
Skills required: We are seeking a motivated student interested in developing skills and models for exploration of cancer growth. They should have a background in some aspect of biological sciences or related field. Previous courses in biochemistry, molecular biology and protein or gene function or other relevant fields of study would be key to contributing to the project goals. Some molecular research experience, particularly mammalian cell culture would be an asset. Good English oral and written communication skills and experience with critical reading of scientific literature will optimize the student’s experience and provide opportunities for them to present/publish their research work.
115. Testing novel drugs for the treatment of acute myeloid leukemia.
Supervisor: Ted Lakowski
University: University of Manitoba (Winnipeg campus)
Overexpression of HOXA genes leads to proliferation of progenitor cells, cessation of differentiation, and AML. To function, HOXA proteins must bind with partners that regulate where HOXA genes bind in the genome and therefore, which genes they control. The most relevant of these partners with respect to AML are the pre-B cell leukemia (PBX1-3), and myeloid ecotropic integration site (MEIS) families of TFs. Consequently, HOXA, PBX, MEIS and their complexes have been validated as targets for AML drug discovery. The project involves evaluating novel drugs that we have developed that target the partners and complexes of HOXA, including PBX and MEIS. The AML cell lines MOLM13 and THP1 that overexpress HOXA genes will be treated with the novel drugs. Chronic myeloid leukemia cell line K562 that do not express HOXA genes will be used as a control group. We will measure changes in cell viability using the MTS assay with increasing novel drug dose and calculate IC50. We will measure expression of genes involved in AML with and without treatment at the mRNA and protein levels using qPCR and ELISA, respectively. We will also measure the effects of the novel drugs on the induction of early and late apoptosis. The effects of the novel drugs on DNA and histone modifications will be measured using analytical mass spectrometry methods we developed.
Research area, student roles & skills
Research area: Acute myeloid leukemia (AML) is an aggressive blood cancer representing ~80% of acute leukemia and affecting nearly 150,000 people worldwide. Despite improvements in treatment, the 5-year survival rate is low ~30%, so new innovative treatments are needed. The homeobox (HOXA) family of genes are conserved transcription factors (TFs) and their overexpression is involved in AML. Even though HOXA proteins are validated targets for AML drug discovery, there are no HOXA inhibitors because as TFs, they lack binding sites for ligands and substrates that receptors and enzymes have. Even if a candidate “inhibitor” binds to a TF, it may not have
Student roles: The students will be responsible for passaging cell lines involved in the study as well as plating cells and performing drug treatment studies by preparing dilutions of drugs. Students will measure cell viability using the MTS assay according to established methods. The students will also extract mRNA and protein from treated and untreated cells and measure mRNA gene expression using qPCR and corresponding protein expression using ELISA. Various assays will be employed to evaluate early and late apoptosis. If time permits the students will assist with the quantification of DNA and histone modifications using analytical mass spectrometry.
Skills required: My laboratory will provide training in cell culture, and drug treatment approaches and curve fitting to determine IC50. The students will also learn to use qPCR, ELISA, tests to measure apoptosis and potentially measurement of histone and DNA modifications using mass spectrometry. The students should have a background in chemistry, biochemistry, molecular biology, medicine, medical or health sciences, pharmacology or pharmacy. It is expected that the student can prepare buffers and solutions, understand the operation of a pipet, and basic calculations. Laboratory safety is one of our primary concerns and as such students should be familiar with basic laboratory safety
116. The impact of mitochondrial dysfunction on inflammation, dysbiosis, and Aβ pathology in AD-like Drosophila model
Supervisor: Ana Silva
University: University of Saskatchewan (Saskatoon campus)
Alzheimer’s disease (AD) is a progressive neurodegenerative disorder marked by amyloid-beta (Aβ) accumulation, synaptic dysfunction, inflammation, and neuronal loss. While much research has centered on brain-specific mechanisms, emerging evidence highlights the gut-brain axis as a critical modulator of neurodegeneration. In particular, mitochondrial dysfunction in peripheral organs such as the gut may contribute to AD pathogenesis by influencing microbial composition, inflammation, and systemic signaling to the brain.
This project aims to investigate whether mitochondrial alterations in the gut play a central role in promoting microbial dysbiosis, inflammation, and increased intestinal permeability in the context of AD. Using a Drosophila melanogaster model that expresses human Aβ1-42, we will compare mitochondrial profiles in the gut of AD-like flies with those of healthy controls. Drosophila models are ideal for this work due to their genetic tractability, short lifespan, and ability to replicate key features of AD, including neurodegeneration and behavioral deficits.
In Objective 1A, we will assess differences in mitochondrial function, morphology, and dynamics in the gut tissue of AD-like versus control flies. In Objective 1B, we will examine how these mitochondrial differences correlate with gut microbiota composition, inflammatory markers, and gut permeability. This will involve microbial DNA sequencing, immunoassays for inflammation, and dye-based assays for barrier integrity.
The overarching goal is to determine whether mitochondrial dysfunction in the gut serves as an upstream driver of systemic changes that exacerbate Aβ pathology. This work will provide novel insights into the role of peripheral mitochondria and the microbiota-gut-brain axis in AD, opening new avenues for therapeutic strategies targeting gut health to mitigate neurodegeneration.
Research area, student roles & skills
Research area: Our research is dedicated to understanding how the gut-brain axis, metabolic shifts—particularly those associated with mitochondrial dysfunction—and inflammation impact brain homeostasis and function, ultimately influencing mood and overall well-being. Utilizing well-established model systems such as Drosophila melanogaster, we aim to characterize mitochondrial profiles in both the gut and brain to shed light on the complex, multifactorial pathophysiological processes underlying neurodegenerative and mood disorders. Our team brings strong expertise in fruit fly genetics, molecular biology and behavioral neuroscience. Our mission is to unravel the biological mechanisms driving brain dysfunction, with the goal of advancing targeted therapeutic strategies that promote brain health.
Student roles: phases of the study: Weeks 1–4: Training and Pilot Work Complete mandatory safety and ethics training (biosafety, animal handling). Learn Drosophila handling, gut dissection, and mitochondrial isolation techniques. Practice Smurf assay, RNA extraction, and qPCR. Prepare materials and perform pilot tests for mitochondrial and gut assays.
Weeks 5–8: Experimental Phase Isolate mitochondria and perform ATP, ROS, and ETC activity assays. Collect samples for metabolomics and proteomics. Dissect gut tissues for microbiome (16S/ITS) and inflammation (qRT-PCR) analyses. Conduct Smurf assay to assess gut permeability.
Weeks 10–12: Data Analysis and Presentation Analyze mitochondrial, gene expression, and gut permeability data. Assist in interpreting proteomic and microbiome results. Prepare figures and report findings in a short manuscript. Present results at a lab meeting or student symposium.
My training program will focus on nurturing essential academic skills, including theoretical knowledge acquisition, laboratory techniques, data analysis, and scientific communication through team meetings and journal clubs. I will foster a welcoming environment that meets needs of both domestic and international students and organize social events to promote team bonding and collaboration. To ensure a smooth transition for the international student, I will actively engage with the International Student and Study Abroad Centre as well as the International Office. I will be available during and outside regular office hours to provide support.
Skills required: The student should have a background in biological sciences, neuroscience, molecular biology, genetics, pharmacology, or related fields, with solid knowledge of molecular and cellular biology. Basic lab skills such as pipetting and solution preparation are required. Experience with techniques like DNA extraction, PCR, histology, or model organisms, especially Drosophila, is a plus. Familiarity with data analysis tools (e.g., SPSS, ImageJ) is also beneficial. Strong communication skills, both written and verbal, are essential for teamwork and presentations. The student must be detail-oriented, able to work independently and collaboratively, and committed to following protocols and safety guidelines.
117. The investigation of the role of a Rac1/Cdc42 regulator in development and cancer
The Rho family of small GTPases holds central functions in cell proliferation, migration, and adhesion. Alterations in Rho genes are linked to many human cancers and indicate a role in tumor invasion and metastasis. Cdc42 GTPase-activating protein (CdGAP, also known as ARHGAP31) is a member of the large family of RhoGAPs that negatively regulates the activity of Rac1 and Cdc42 small GTPases. Associated with a rare developmental disorder (the Adams-Oliver Syndrome), CdGAP plays important roles in the regulation of cell migration and proliferation during early development. In addition, CdGAP is critical during vascular development and act as an oncogene to promote breast cancer. In this project, we will use CdGAP-deficient mouse models and human breast cancer cell lines to test the hypothesis that CdGAP is a positive modulator of breast cancer through its transcriptional activity. We will use various breast cancer cell lines and we will inactivate the CdGAP gene or introduce knock-in point mutations using the CRISPR/CAS9 approach. We will then examine the role of CdGAP in cell migration, adhesion, tumor formation, and metastasis in xenograft mouse models. Overall, this summer research project will highlight the importance of the protein CdGAP in the development of breast cancer, which may impact on the discovery of novel biomarkers and therapeutic strategies for breast cancer.
Research area, student roles & skills
Research area: Dr Lamarche-Vane’s lab investigates molecular mechanisms involved in the regulation of cell migration and adhesion, linked to development and human diseases. For instance, in the adult, migration events are involved in the normal physiology as well as in pathology such as metastasis. In embryogenesis, cell migration is an important feature of the development of the nervous system. Dr Lamarche-Vane is interested to uncover novel mechanisms underlying the role of the Rho GTPases in cell migration, in particular, in the developing nervous system and in the cellular processes leading to metastasis using global molecular and cellular approaches.
Student roles: The student will be matched with a postdoctoral fellow or a senior PhD student in the lab to be trained for the specific research project. The student will learn on a day-to-day basis cell culture, transfection, CRISPR/CAS9 approaches, western blot analysis and immunofluorescence. The student will be trained and then, will be able to accomplish independently the experiments under the supervision of the postdoc or PhD student. The student will learn how to critically analyze the data, how to organize them and will meet with Dr Lamarche-Vane every week to discuss the data and the follow-up strategies.
Skills required: The student should have some basic knowledge of molecular and cellular biology. Some background in the basic signaling mechanisms involved in the regulation of cell proliferation and cell migration will help but is not absolutely essential.
118. The role of MeCP2 on controlling protein translation in the brain
Supervisor: Mojgan Rastegar
University: University of Manitoba (Winnipeg campus)
It is well known that in the brain cells, MeCP2 loss leads to impaired protein translation. However, the molecular mechanisms by which MeCP2 controls this process are unclear. The student will perform gain and loss-of-function studies in a brain cell line (Daoy cells) with our existing lentiviral vectors to study the role of MeCP2 on regulating the components of the protein translation machinery. Control experiments will confirm the overexpression and knockdown of MeCP2 (at the transcript and protein levels ) in these cells. For these studies, we will collect total protein extracts from the transfected/transduced cells with overexpressing and shRNA vectors and subject them to Western blot protein analysis for eIF2a/b, eIF4E, E-BP (pan and phosphorylated), and ribosomal proteins, among other relevant proteins. The outcome of these studies will contribute towards a better understanding of the mechanisms by which MeCP2 controls protein translation in the brain.

119. The role of mitochondria in setting heat thermal tolerance in insects
Temperature is among the most important environmental stressors that can be a major driving force impacting molecular, metabolic and physiological aspects of phenotype, especially in ectotherms as their body temperature is closely associated to environmental temperature. As they have colonized and are thriving in almost all ecosystems and thermal niches, insects are a particularly successful order at dealing with the effects of temperature. At the cellular level, mitochondria are highly influenced by temperature and, as the hub of aerobic metabolism, they have been under scrutiny in the past few years as an important keystone explaining thermal limits of ectotherms. Although mitochondrial thermal sensitivity has been suggested to be important for thermal tolerance and adaptation in several ectothermic species, insects have often been overlooked, resulting in a gap of knowledge concerning the implication of mitochondrial functions in the thermal physiology of insects. The aim of this project will be to use a comparative approach to determine the implication of specific mitochondrial proteins in setting the upper thermal limits of insects. For this purpose, strains of Drosophila melanogaster with targeted knock-down will be used and their mitochondrial functiosn will be evaluated.
Research area, student roles & skills
Research area: I have a broad-range of interests and skills in comparative physiology, metabolism and evolution. Particularly, I am trying to integrate different approaches such as molecular biology, biochemistry, physiology and evolutionary biology to study the physiological and metabolic adaptations that enable different species (Insects, Fish, Marine Invertebrates, Mice) to live in a particular environment under different constraints.
Student roles: The student will perform laboratory experiments (qPCR, mitochondrial oxygen consumption, ATP production, enzymatic activities) and will be in charge of analysing the results and produce the figures. The student will also be in charge of raising the drosophila and produce the knock-down strains.
Skills required: Background in biochemistry (metabolism) and biology. Skills in laboratory experiments such as molecular biology, measurement of enzymatic activities and mitochondrial oxygen consumption as well as experience with the Drosophila melanogaster model is an asset.
120. Transcriptional Condensates in Health, Disease, and Therapy.
Supervisor: Nada Lallous
University: University of British Columbia (Vancouver campus)
Biomolecular condensates regulate critical cellular processes, including signaling, stress response, and
transcription. Their deregulation is implicated in cancer and neurodegeneration. Our recent work
identified that the androgen receptor forms liquid-like condensates in response to androgen stimulation
in prostate cancer cells. These transcriptionally active condensates are also shared among other steroid
receptors. However, the role of condensate formation in driving specific transcriptomic programs and its
dependence on cellular context remains poorly understood. This program aims to elucidate the
mechanisms by which transcriptional condensates regulate oncogenic programs, drive treatment
resistance, and contribute to cancer progression. Using a multidisciplinary approach combining
biophysics, proteomics, biochemistry, and cell biology, we will characterize condensate properties,
identify condensate-specific proteomic and transcriptomic signatures, and validate their relevance in
preclinical models.
Research area, student roles & skills
Research area: I am a structural biochemist interested in applying my strong expertise in protein biochemistry and biophysics to guide drug development for cancer patients. My research program is currently focused on understanding the role of AR transcriptional condensates in order to identify new therapeutic options for patients with advanced forms of prostate cancer.
Student roles: The student will be expected to transfect cancer cells with different variants of the androgen receptor and evaluate the effect on the transcription of key oncogenic pathways.
Skills required: The project involves cell culture, protein biochemistry, and microscopy skills. Therefore, students with a strong background in Cell Biology and/or Biochemistry will be best suited for this position.
121. Tumour-on-a-chip with enzymatic electrochemical monitoring of cancer cell microenvironment
Supervisor: Anna Ignaszak
University: Brock University (St. Catherines campus)
Background: The FDA aims to cut animal testing in drug development, with Canada possibly following. This challenge demands advancing in vitro models to replace some animal tests. Animal models struggle to accurately predict human cancer, with a success rate under 8%, due to species differences, cell culture conditions, and tumor complexity. While essential for initial screening, their predictive limits highlight the need for alternatives. Tumour-on-a-chip (ToC) offers promising prospects, potentially enhancing drug development by yielding more reliable results. Testing antibody therapies in rodents can extend timelines by 4-5 years and cost $2-4 million, but ToC enables faster, high-throughput testing, reducing time and costs. Although savings depend on various factors, benefits are clear.
Aim of the project: Our goal is to design ToC hardware with in situ electrochemical sensors to measure lactate and glucose, crucial for cancer metabolism. Cancer cells favor glucose for energy via aerobic glycolysis, producing lactate that aids tumor growth and metastasis. Therapies are focused on blocking glucose metabolism and targeting lactate production, transport, or use.
Experimental approach - Biochips are made from injection-moulded polymers with chambers featuring three vertically stacked channels, each with Luer inlets and outlets. Channels on the top and bottom are sealed, separated by porous membranes that serve as cell culture surfaces. Each channel holds 200-300 μL, using less medium than traditional cultures. The membrane between the middle and bottom channels has 25 microcavities for spheroids or cells. The top and bottom channels connect to a peristaltic pump for perfusion with medium mimicking the tumour microenvironment; the middle channel with tumor cells is sealed. The ToC microchip integrates enzyme sensors for lactate and glucose in a droplet network by immobilizing oxidase enzymes in a hydrogel beneath the cancer cell channel, excluding external influences. This setup provides real-time metabolic data of microtissues.

123. Understanding and treating RASopathy-associated hypertrophic cardiomyopathy
This research project focuses on developing and utilizing iPSC-based and animal models to study hypertrophic cardiomyopathy (HCM) in RASopathies, with a specific emphasis on alleles that exhibit severe phenotypes or resistance to MEK inhibitor treatment. While MEK inhibitors have shown promise in preclinical models and early clinical trials, certain patient alleles exhibit severe cardiac phenotypes or demonstrate no clinical response to MEK inhibition.
To address this critical gap, we will generate induced pluripotent stem cells (iPSCs) from patients or mice harboring these challenging mutations. We differentiate iPSC into cardiomyocytes, and establish robust in vitro models that faithfully recapitulate the HCM phenotype. Using advanced cellular imaging, electrophysiology, molecular biology, and biochemistry techniques, we will dissect the specific signaling pathways and molecular mechanisms driving cardiomyopathy in these cells. Analogous studies are carried out in mouse models in vivo.
Particular focus will be placed on identifying alternative or compensatory signaling routes, such as parallel kinase cascades or feedback loops, that may bypass MEK inhibition and explain treatment resistance.Through targeted drug screening of compound libraries, including FDA-approved drugs and novel small molecules, and testing of combination therapeutic approaches, we aim to discover and validate new treatment strategies that can effectively ameliorate HCM in these treatment-resistant cases. The ultimate goal is to translate these findings into precision medicine approaches for RASopathy patients with severe or MEK inhibitor-refractory cardiac disease.
Research area, student roles & skills
Research area: Our laboratory investigates RASopathies—a group of rare genetic disorders caused by germline mutations in the RAS/MAPK signaling pathway, including Noonan, Costello, and cardio-facio-cutaneous syndromes. These conditions share clinical features such as developmental delays, congenital heart defects, and increased cancer risk. We study the molecular and cellular mechanisms that drive disease pathology to identify druggable targets. Our translational research aims to develop novel therapeutic strategies.

124. Understanding biofilm development in the fungal pathogen Pestalotiopsis clavispora through transcriptome analysis
Biofilms are structured microbial communities that attach to surfaces and are embedded within a self-produced matrix. Biofilm formation plays important roles in the survival, persistence, and pathogenicity of many microorganisms, including plant-associated fungi. However, the molecular mechanisms that regulate biofilm development in the fungal pathogen Pestalotiopsis clavispora remain poorly understood.
The goal of this project is to characterize the gene expression changes that occur during biofilm formation using RNA sequencing (RNA-seq). The student will establish and optimize laboratory conditions for reproducible biofilm formation in vitro and monitor biofilm development over time using microscopy and quantitative measurements. These observations will be used to identify key developmental stages and select appropriate sampling time points representing different phases of biofilm formation.
High-quality RNA samples will be collected from these selected stages and subjected to RNA-seq analysis. The resulting transcriptomic data will provide a comprehensive view of the genes and biological pathways that are activated or repressed throughout the process. Bioinformatics analyses will be used to identify gene expression patterns associated with biofilm initiation, maturation, and maintenance.
A major outcome of the project will be the identification of candidate molecular markers that can reliably distinguish different stages of biofilm development. These markers will serve as valuable tools for future studies aimed at understanding the regulation of fungal biofilms and evaluating strategies to disrupt biofilm formation. The project will generate foundational knowledge of P. clavispora biology while providing training in microbiology, molecular biology, RNA sequencing, and bioinformatics. Insights gained from this work may ultimately contribute to improved management of fungal diseases affecting agriculturally important crops.

125. Understanding invisible links in the global carbon cycle by linking microbiology and chemistry
Supervisor: Andrew Tanentzap
University: Trent University (Peterborough campus)
Organic matter is one of the most important fluxes in the global carbon cycle, so predicting how it will change into the future has important implications for climate change mitigation and adaptation. A major limitation of state-of-the-art Earth system models used to forecast the global climate is that they assume organic matter can be represented by a handful of uniform pools and microorganisms, which drive most carbon exchange between the atmosphere and land interact identically with these pools. However, advances in analytical chemistry have revealed that organic matter is much more diverse than is implied by its interchangeability with carbon. Organic matter consists of tens of thousands of unique molecules of varying origin, form, and function. These molecules uniquely reflect the sources of primary production from which they originate and vary spatially and temporally in the environment just like diverse communities of biological species. A new theory now proposes that the persistence of carbon in different environments arises from the interactions between individual molecules and microbes, challenging the long-held view that only chemical properties determine the fate of molecules.
This project will determine how the molecular diversity of organic matter influences microbial composition and functioning. The specific activities will be tailored to the student's interest but these can include field work linking ecosystem-scale measurements linking microbial and chemical diversity, computational analyses leveraging metagenomics and ultra-high-resolution mass spectrometry datasets, or laboratory experiments where synthetic microbial communities cultured for generations on varying organic matter. The outcomes of this research will help answer how “species” of both molecules and organisms coexist in nature, influence ecosystem function, and can be categorised into functional groups in Earth system models. Ultimately, this research will help improve prediction and mitigation of climate change.
Research area, student roles & skills
Research area: Our research group studies how environmental change impacts biodiversity and the benefits that nature delivers to people, such as clean drinking water, climate regulation, and food production. These benefits are in part delivered by how microorganisms break down and transform different organic substrates. We merge theory and approaches from biology and chemistry to study how organic substrates are changing because of climate change and the implications for microbial metabolism and evolution at the level of entire ecosystems. The outcomes of our research will help society mitigate the impacts of climate change and improve models of the global climate system.
Student roles: The student will work in a team of graduate students and postdoctoral researchers to undertake field and laboratory work related to organic matter biogeochemistry and climate change. The field work will involve collecting organic matter from lakes and their surrounding soils along a climate gradient in Canada. We will take in-situ measurements with specialised probes for temperature, pH, oxygen/chlorophyll levels, and greenhouse gas emissions. In the lab, the student will learn analytical chemistry techniques like solid phase extraction to extract organic matter from the samples and analyse the extracts on one of the most advanced mass spectrometers in the world: a Fourier-transform ion cyclotron resonance mass spectrometer at the Trent University Water Quality Centre. Samples will also be used to measure microbial activity, such as with spectrophotometric enzyme assays, and biomass with flow cytometry, and the student will be trained in these techniques. Finally, we will characterise the composition and function of microbial communities collected from the environment using state-of-the-art long-read and single-cell sequencing. The student will be trained in nucleic acid extraction, library preparation, as well as bioinformatics. There will also be an opportunity to participate in long-term microbial evolution experiments and learn how to culture microorganisms and undertake community competition experiments. The student will undertake statistical analyses that link the taxonomic and functional composition of microorganisms to organic matter composition and reactivity. Throughout, the student will learn standard laboratory operating procedures and statistical modelling (including computer programming). The student will also be provided with all relevant health and safety training, including for outdoor field work and first aid in remote locations.
Skills required: The student should be enrolled in a degree in biology, chemistry, geography, earth sciences, or a similar discipline. Ideally, the student will already have some laboratory and fieldwork experience and skills in data science (e.g. relevant courses), but training will be provided by our research group in molecular biology and analytical chemistry techniques as well as bio/chemoinformatics.
126. Unlocking the cellular nitrogen storage potential for boosting nitrogen use efficiency in plants
Supervisor: Jae-Hyeok Lee
University: University of Manitoba (Winnipeg campus)
All organisms on earth rely on the products of photosynthesis that harnesses sunlight energy into organic carbons (or sugars). Efficient photosynthesis requires coordinated metabolic flow and thereby subjected to intense regulation under environmental stressors, whose molecular mechanisms remain elusive. A facultative phototroph, Chlamydomonas reinhardtii degrades photosynthetic complexes under nutrient starvation but only when alternative organic carbon such as acetate is available, offering an excellent model to investigate C/N-response mechanisms. Using C. reinhardtii, Lee laboratory has examined various growth regimes of varying C/N conditions and isolated genetic mutants impaired in responses to changing C/N conditions. First, arginine-fed cultures constitutively turn on nitrogen (N) starvation-induced genes and increased lipid droplets during exponential growth, indicating decoupling of the cellular signaling from metabolic N starvation. Second, a genetic screening for defective photosystem degradation in acetate-fed conditions identified two signaling mutations. Lee lab hypothesizes that these signaling proteins mediate the mixotrophy signal to regulate the degradation of photosynthetic machinery. To test this hypothesis, students will characterize wild-type and these mutants in arginine-fed conditions with or without exogenous acetate feeding. I expect to find preserved photosynthetic machinery in arginine-fed mutants, resulting in higher carbon flow from photosynthesis and accumulation of starch/triacylglycerole, the major carbon storage forms. Students' work will involve the molecular genotyping of C. reinhardtii strains and bioreactor-based monitoring of their growth, photosynthetic machinery, and cellular carbon storage. Having my experimental data to test a working hypothesis, students will be able to acquire a full-scale experience on how a science project is planned, executed, and interpreted.
Research area, student roles & skills
Research area: LEE laboratory is studying microalgae, focused on their nitrogen use efficiency, for mitigating global impact of carbon emission. Genetic mutations of key players involved in nitrogen starvation responses help decipher molecular mechanisms of

Daily report: The students will be expected to write down the details of the tasks done for the day and planned for the next day.
Skills required: College-level working knowledge in cell biology and genetics. Minimum 6 months of working experience in lab-based environments. Organizational skills in collecting and summarizing numerical data.
127. Urethral reconstruction using tissue engineering, final steps towards clinical translation
We propose to reconstruct a urethral substitute using patient’s cells: autologous and free of synthetic material. No other team in Canada is involved in the search for alternatives and we have been leaders in the field of uro-gynaecological tissue engineering for 15 years. The reconstructed urethra should provide better surgical material for correcting complicated congenital anomalies in children. We will test the construct in a rabbit model.
Research area, student roles & skills
Research area: Urologic patients often present congenital/acquired pathologies requiring surgical reconstruction. Still, it has been challenging due to the limited availability of tissues, especially for the urethra. Therefore, it represents a significant public health issue because nearly 2% of men will suffer from these pathologies, and it has a considerable psychological impact. Interestingly, tissue engineering is a developing field that aims to replace or regenerate these dysfunctional tissues.
We are interested in urethral tissue engineering, an under-researched field. A genitourinary tubular graft was successfully assembled. It became apparent to use this tubular urological tissue as a urethral substitution model.
Student roles: The student will closely work with a PhD candidate, and perform 2D and 3D cell culture. The student will also analyse the reconstructed tissues (histology, immunofluorescence, ELISA, Western blot, and functional assessment (permeability assay and mechanical resistance).
Skills required: Knowledge in cell biology, cell culture, basic and advanced microscopy and histology. Maintaining a good quality lab book. Mandatory in lab safety and cell culture training.
