Contact Aubert Michaud, retraité


Aubert Michaud (Ph.D) holds a doctorate in soils from Université Laval, as well as a bachelor's and master's degree in the same field from McGill University. From 1987 to 1997 he worked at Ministère de l’Agriculture, des Pêcheries et de l’Alimentation du Québec. There, he assisted agricultural stakeholders in the transition to soil conservation practices by coordinating continuing education activities, farm trial networks, and technical and financial guidance programs for agricultural businesses. Aubert has been with IRDA since 1998, where he and his team describe the processes that underlie nonpoint source contamination of surface water in agricultural areas and develop tools to manage it. He is also an associate professor in the Department of Civil Engineering and in the Department of Soil and Agri-Food Engineering at Université Laval.
