Francis Zwiers

Director, President and CEO

Before becoming Director of the Pacific Climate Impacts Consortium, Dr. Zwiers served as a Research Scientist (1984-2006), Chief of the Canadian Centre for Climate Modelling and Analysis (1997-2006) and Director of the Climate Research Division (2006-2010), all at Environment Canada. He is an Adjunct Professor in the Dept. of Mathematics and Statistics of the University of Victoria and in the Dept. of Statistics and Actuarial Science of Simon Fraser University. His expertise is in the application of statistical methods to the analysis of observed and simulated climate variability and change. Dr. Zwiers is a Fellow of the Royal Society of Canada and of the American Meteorological Society, a recipient of the Patterson Medal, has served as an IPCC Coordinating Lead Author of the Fourth Assessment Report, and is an elected member of the IPCC Bureau.
