Profile

I pursued graduate work at the University of Toronto with a major in biochemistry and minor in nutrition for the purpose of exploring how altering dietary fat types could alter biochemical pathways via various mechanisms with resulting benefits or detriments to human health.

My dissertation research was focused on the metabolism of essential fatty acids in vivo and their incorporation into membrane phospholipids. My post-doctoral work at the University of Michigan as supported by a MRC Fellowship allowed me to pursue studies on structure/functional relationships of polyunsaturated fatty acids in cellular systems. When I joined the Department of Nutrition (now Department of Human Health and Nutritional Sciences) at the University of Guelph, I focused my research on the potential benefits of omega-3 fatty acids from plant and fish sources with respect to cardiovascular health in humans including research on nutraceuticals/functional foods containing these fatty acids. As well, I have long studied the potential deleterious effects to human health of trans fatty acids found in processed and fast foods.

I have been most privileged to work with numerous dedicated and caring graduate students, research assistants, and collaborating colleagues from Canada and other countries during my research career. I have served as President of the Canadian Society for Nutritional Sciences and Chairman of the Nutrition Task Force for the Heart and Stroke Foundation of Ontario. I am also most appreciative of the awards granted to me including the Borden Award from the Nutrition Society of Canada, The McHenry Award from the Canadian Society for Nutritional Sciences, being elected a Fellow of the International Academy of Cardiovascular Sciences, the Gordin Kaplan award from the Canadian Federation of Biological Societies, and more recently, the 2006 Distinguished Nutrition Leadership Award from the Danone Institute at the Canadian Nutrition Congress in Winnipeg.

I have served on the editorial board of the Canadian Journal of Physiology and Pharmacology as well as Lipids.

Research

Omega-3 fatty acids from fish, fish oils, and plant sources for human health and cardiovascular care. 'Trans' fatty acids and the risk of cardiovascular disease. Nutraceuticals and functional foods. Collaborative research with agri-food units on campus directed towards the development and human evaluation of nutritionally-enhanced and value-added animal products (omega-3 eggs, DHA-milk, etc.) and clinical studies on EPA/DHA concentrates.
