Dr. David Ma obtained his PhD in Medical Sciences in 2001 at the University of Alberta conducting research on the anticancer properties of conjugated linoleic acids in breast cancer. He then moved to Texas A&M University where he did postdoctoral research investigating the role of omega-3 fatty acids and folate in colon cancer. He returned to Canada where he joined the Department of Nutritional Sciences at the University of Toronto as an Assistant Professor in 2004. Then, in 2007 joined the faculty in the Department of Human Health and Nutritional Sciences at the University of Guelph where he is currently Professor and Director of the Guelph Family Health Study.
The long term objective of Dr. Ma’s research program is to increase our fundamental knowledge of the role of dietary fatty acids in human health and disease. Currently, research is primarily focused on breast cancer prevention and how omega-3 fatty acids modify mammary gland development, signaling, and tumour development through the lifecyle. 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 his academic responsibilities, Dr. Ma is also very active in his society serving on several committees and a former President of the Canadian Nutrition Society. He has also served on grant review panels (CIHR & Cancer Research Society), 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.
