Biography

Dr. Michael Riddell is a Full Professor in the School of Kinesiology and Health Science at York and the founder of the York University Diabetes Sports Camp. His global interests center on the effects of exercise and stress on diabetes and metabolism. He is the Principle Investigator for the Canadian Foundation for Innovation Exercise Physiology & Endocrinology Laboratory for the Study of the Metabolic Syndrome and Diabetes.

 

Dr. Riddell is also a founder and Chair of the Scientific Advisory Board for Zucara Therapeutics Inc., a spin-off company from The Centre for Drug Research and Development and MaRS Innovation that is advancing a novel technology that prevents hypoglycemia in insulin-treated diabetes. He is also a Senior Scientist at LMC Diabetes and Manna Research in Toronto where he leads clinical studies on glucose management strategies for exercise in type 1 diabetes.

 

Dr. Riddell has published more than 170 peer-reviewed journal articles, 20 book chapters, and one patient guidebook on the metabolic and hormonal responses to exercise and stress in diabetes. He has authored several international guidelines on exercise and diabetes and he engages with several community-based diabetes sports and exercise programs, including Dskate- a hockey camp for kids living with type 1 diabetes. He has over 200 invited scholarly talks and keynote lectures at various academic, scientific, professional and public events.

 

A recipient of the Faculty of Health Dean’s Established Career Research Award, Riddell currently holds research grants from various funding agencies and industry partners totaling ~$4M. His research team uses a broad selection of innovative models and techniques to discover how regular exercise, stress and diabetes influence metabolism and health.
