Claude Duguay is University Research Chair in Cryosphere & Hydrosphere from Space and Professor in the Department of Geography & Environmental Management at the University of Waterloo, Canada. He received his B.Sc. from the Université de Montréal, M.A. from the State University of New York at Buffalo, and Ph.D. from the University of Waterloo. He has held previous faculty positions at the University of Ottawa, Université Laval, and the University of Alaska at Fairbanks before returning to his alma mater in 2006. His main research interests are in remote sensing, field observations and modeling of cold regions processes with the goal of deepening knowledge, understanding and predictive capabilities of lake/land-atmosphere interactions. Current work includes the development of satellite-based lake products from active/passive microwave and optical data, the response of lakes to contemporary and future (projected) climate conditions, the role of lakes in weather and climate, and improvement of the representation of cryospheric processes in lake model schemes as implemented in numerical weather prediction and climate models.
