Professor, College of Biological Science, University of Guelph


David Josephy graduated from the University of Toronto and the University of British Columbia and was a post-doctoral fellow at NIEHS, North Carolina. He joined the Department of Chemistry, University of Guelph (Ontario, Canada) in 1983. The biochemistry faculty at Guelph joined the new Department of Molecular and Cellular Biology in 2004. Josephy has taught Biochemistry to thousands of students, at introductory, intermediate, and graduate levels. He developed a senior-level course in Biochemical Toxicology and is the co-author of "Molecular Toxicology, 2nd ed." (Oxford University Press, 2006).

Josephy has supervised more than 30 graduate students and published more than 120 scientific papers. His research interests include the analytical chemistry of environmental carcinogens; mechanisms of xenobiotic bioactivation; and enzyme structure and function. The concept of bacterial mutagenicity strains expressing recombinant human enzymes of bioactivation, pioneered in the Josephy lab., has been widely adopted.

Josephy has served on many granting agency review panels in Canada and is a member of the College of Reviewers for the Canada Research Chairs program. He has served as President of the Society of Toxicology of Canada and is Co-Editor-in-Chief of Mutation Research - Genetic Toxicology and Environmental Mutagenesis.
