I obtained my PhD in Medical Sciences in 2001 at the University of Alberta conducting research on the anticancer properties of conjugated linoleic acids in breast cancer. After my PhD, I moved to Texas A&M University where he did postdoctoral research investigating the role of omega-3 fatty acids and folate in colon cancer. I later returned to Canada where I joined the Department of Nutritional Sciences at the University of Toronto as an Assistant Professor in 2004. Then, in 2007 I joined the faculty in the Department of Human Health and Nutritional Sciences at the University of Guelph where I am currently a Full Professor.The long term objective of my research program is to increase our fundamental knowledge of the role of dietary fatty acids in human health and disease. I am interested in the effects of fats throughout the life cycle from in utero to old age in both the prevention and treatment of disease. Bioactive fats studied by my group include omega-3, omega-6, trans, and conjugated linoleic acids. Specific interests include omega-3 fatty acids in breast cancer, bone development, Alzheimer's disease, fatty liver disease, metabolism of omega-3 and omega-6 fatty acids and nutrigenomics. Currently, my research is primarily funded in the area of breast cancer prevention examining how omega-3 fatty acids modify mammary gland development, signaling, and tumour development. In addition, he is the Director of the Guelph Family Health Study, one of the largest active family cohorts in Canada. This cohort examines determinants of health and tests interventions for the prevention of childhood obesity.In addition to my academic work, I am active in the Canadian Nutrition Society, and currently hold the position of Past-President. I have also served on CIHR grant review panels, consulted for the food/fats & oils industry, and provided scientific leadership in the development of an unsaturated fat and cholesterol reduction health claim in Canada.
