François Tardif is a weed scientist and professor at the University of Guelph. He teaches at the bachelor's and diploma level, trains graduate students and conducts research on herbicide activity, weed biology and integrated weed management. François studied agronomy at Laval University, Quebec City, and obtained his bachelor's degree in 1985. Having worked on the provincial weed survey in 1982 and 1983, he decided to pursue a career in weed science. Thus, he began his master's and doctoral studies, under the supervision of Dr. Gilles Leroux at the Department of Plant Science at Laval University focusing his research on the control and physiology of quackgrass. Dr. Tardif received his PhD in January 1991 and then worked in Australia at the University of Adelaide under the supervision of Professor Stephen Powles, aiming to understand the physiology of herbicide cross-resistance in annual ryegrass. He joined the University of Guelph in 1996 and is conducting most of his research on understanding and managing herbicide resistance as well as the management of invasive plants such as giant hogweed and wild parsnip. Dr. Tardif has taught multiple classes on various aspects of agronomy and weed science and supervised or co-supervised more than 45 graduate students.
