Urban stormwater management
Stormwater management (in both quantity and quality) has obtained significant impetus in the wake of increasing concerns over both our water resources and natural ecosystems. The objectives of stormwater management for urban settings are to reduce stormwater amount and improve stormwater quality to avoid the quality degradation in natural receiving water bodies. My research on this subject is more focusing on the Low Impact Development technologies (LIDs) including permeable pavements, green roofs, and bioretention systems. The research conducted in this area aims to understand their performance as well as to identify the challenges/or problems in their implementation and thus enhance their engineering design for better managing urban stormwater. I am also very interested in developing new approaches for water quality statistical analysis to identify the causes of water quality degradation for helping to formulate more effective water quality management strategies.
Climate change impact on water resources
Climate is changing and climate change will continue. Climate change affects all aspects of hydrological cycle and thus water resources management. My research interests in this area are to understand to what degree climate change affects water quantity and quality and in turn to help in adapting the changes in water resources. My current research focuses on this subject are to explore: (1) to what degree the magnitude and frequency of hydrological extreme events (including rainfall and flow) change; (2) how to deal with the non-stationary hydrological processes and time series, which are resulted from climate change as well as other changes, in hydrological modeling and analyses; (3) how to quantify/assess the inherent uncertainties, which are also critical for decision makers, from various sources in hydrological modeling and analyses; and (4) how to enhance the forecasting/projection of hydrological variables and associated uncertainties.
Dr. He joined the Department of Civil Engineering of the University of Calgary as an Assistant Professor in Water Resources Engineering in July, 2013. Prior to this position, she has been an Assistant Professor with Lakehead University, Ontario since September, 2011. Dr. He's research is in the field of water resources engineering particularly focusing on better understanding physical mechanisms through field monitoring and both physically-based and data-driven modeling.
Dr. He has particular interest in advancing the understanding of how to more efficiently manage water resources under both natural and anthropogenic stressors. Her research works have been funded by the Natural Science and Engineering Research Council of Canada (NSERC), Alberta Innovates, MITACS, and other provincial and municipal funding. Dr. He has won the Early Research Excellent Award from Schulich School of Engineering in 2016.
Besides being an academic researcher, Dr. He has also put great efforts in both undergraduate and graduate education. She has won several teaching wards. In addition, Dr. He also actively participates in various advisory committees to provide her expertise to the community.
