1. Assessing plant performance and water quality from urban green roofs
Green roofs are increasingly implemented in cities around the world as a nature-based solution to improve stormwater management while restoring urban ecosystem services. In North America, extensive green roofs often use Sedum species because of their high drought tolerance and low maintenance requirements; however, these systems provide limited ecosystem services. This research project aims to improve plant performance and water quality in green roof systems through substrate design and modification. As part of a larger research project, the student will focus on the operation, inspection, monitoring, and maintenance of green roof experimental plots, as well as the collection of water, plant, and substrate samples for laboratory analysis. During the internship, the student will support experimental operation and maintenance, collect and process samples, assist with laboratory and field measurements, and help organize and summarize research data. The student will gain hands-on experience in green roof research, water quality analysis, plant monitoring, soil and substrate analysis, and environmental monitoring, while strengthening their knowledge of green infrastructure design, stormwater treatment, and experimental research methods. The outcomes of this research are expected to improve the design, monitoring, and performance of green roof systems for stormwater management and ecosystem services. The project will also contribute to broader urban sustainability goals by supporting more effective nature-based solutions for resilient and sustainable cities.
Research area, student roles & skills
Research area: Dr. Liao’s research focuses on green infrastructure, water treatment, water resource management, plant-soil-water interactions, environmental monitoring and remediation, and remote sensing. Her work aims to optimize the monitoring and design of nature-based systems to improve water quality, plant performance, and ecosystem functions. She also investigates the design and application of sustainable, engineered materials for the removal of both traditional and emerging contaminants from water and the environment, while protecting ecosystem health. In addition, Liao employs remote sensing and data science approaches (e.g., meta-analysis) to understand, assess, and optimize vegetation, water, and environmental performance and management at multiple spatial scales.
Student roles:
The student will contribute to a broader research project on improving plant performance and water quality in green roof systems through substrate design and modification. The role will involve supporting the operation, inspection, monitoring, and maintenance of green roof experimental plots, collecting and processing water, plant, and substrate samples, assisting with field and laboratory measurements; and organizing and summarizing research data. The student will play an active role in evaluating green roof performance while gaining hands-on experience in green infrastructure research, stormwater monitoring, plant and soil analysis, and applied environmental sciences.
Skills required:
- Academic background in environmental science/engineering, civil/chemical engineering, engineering, analytical chemistry, plant and soil sciences, landscape architecture or a closely related field.
- Strong interest in applied research focused on water quality, plant science, and nature-based solutions.
- Previous research experience in laboratory analysis and field monitoring relevant to water, plant, or environmental systems.
- Strong analytical, organizational, communication, and teamwork skills.
