I have organized several symposia in recent years; the goal of the symposia has been to convene national and international experts on controversial topics, and to make recommendations for research, practice and policy. I have also worked nationally on the integration of nutrion within inter-professional education. Most recently I have focused on childhood obesity with an emphasis on working with communities to develop prevention strategies. I have also acted in a consulting capacity to sports teams, government agencies, and private industry on issues relating to the translation of science to public policy and to clinical and public health settings.

  • Marie-Pierre St-Onge

    Assistant Professor of Nutrition

    I completed Bachelor's, Master's, and Ph.D degrees in Human Nutrition at McGill University. My Master's degree thesis focused on the impact of kefir, a fermented milk product, on cholesterol synthesis rates and circulating lipid profile in men with overweight and mild hypercholesterolemia. I developed a passion for research and a strong interest in foods that could influence disease risk factors. I therefore decided to pursue a Ph.D, this time studying the effects of medium chain triglyceride oil consumption on energy expenditure, body composition and cardio-metabolic risk factors in men and women with overweight/obesity. Upon completion of my training at McGill, I joined the New York Obesity Nutrition Research Center and the Institute of Human Nutrition as a Post-Doctoral Fellow to further my knowledge in the area of energy metabolism and body composition.
