Biography

Dr Usman T Khan is an Assistant Professor in Civil Engineering at the Lassonde School of Engineering, York University. His research interests lie in Water Resources Engineering, focusing on urban hydrology, including flood risk assessment and uncertainty analysis, sustainable water resource management and infrastructure, and the impacts of climate change on these systems.

Usman received his BSc and MSc from the University of Calgary. His undergraduate project focused on designing a net zero water use building on a university campus. For his MSc research, Usman tested the efficacy of bioretention cells, a type of sustainable stormwater management technology. Usman was awarded a PhD from the University of Victoria; his research contributions included designing new big-data based techniques to improve water quality and quantity analysis in urban areas.

He has won a number of national awards for his research and teaching, including NSERC awards for his MSc, PhD and postdoctoral work, and recently an Andy Farquharson Teaching Excellence Award. In addition to this, Usman has worked with municipal governments, providing his expertise to a number of stormwater, watershed management and urban hydrology projects.

The role of Civil Engineering in creating vibrant, liveable and sustainable cities is a strong motivator for Usman. He is committed to using his professional practice to meet the challenges that face the urban environment.
