Dr. Clarance J. Swanton

Bio:

Dr. Swanton obtained his B.Sc in Botany from the University of Toronto, His M.Sc in Agrometerology from the University of Guelph, and a PhD in Plant Ecology from the University of Western Ontario.  During the years between earning his M.Sc. and his Ph.D, he was employed as a research assistant with the Campbell Soup Company and later as a weed biologist by the Ontario Ministry of Agriculture and Food located on the campus of Ridgetown College.  In 1985 he joined the University of Guelph as a faculty member in the Department of Crop Science. In 1996 he was promoted to full professor.   From 1998 to 2004, Clarence served as the first Chair of the Department of Plant Agriculture which included the Departments of Crop Science, Horticulture and the Horticulture Research Institute of Ontario.  From 2007 to 2008 he served as President of the Canadian Weed Science Society.  His research is focussed on weed ecology and the development of integrated weed management systems for field and horticultural crops. He has won numerous awards for his research including: the Ontario Agricultural College Distinguished Researcher Award, University of Guelph Presidential Distinguished Professor Award,  Excellence in Weed Science Award for Canada, and the Weed Science Society of America’s Outstanding Researcher Award.  He is an elected Fellow of the Canadian Society of Agronomy, the Canadian Weed Science Society and the Weed Science Society of America and recently received the Bayer Science Award for Innovation in 2013.
