POSTDOCTORATE FELLOW
Samantha Stephens received her Masters of Science degree in Exercise Physiology from Ohio University and completed a Ph.D. in Clinical Epidemiology at the University of Toronto. Over the past 15 years, she has been involved in developing and validating physical activity outcome measurement tools to determine activity levels of children with chronic conditions; identifying effective strategies and techniques for changing physical activity behaviours, and conducting clinical trials to study the effects of exercise regimens on walking ability, fitness and quality of life in children with Rheumatological conditions. As a Postdoctoral Fellow in Dr. Yeh’s lab, Samantha has recently examined the long-term impacts of physical activity participation on symptoms of fatigue and depression in children with multiple sclerosis. In addition, she is helping to set up a program of research that will examine how sleep, physical activity and physical fitness impact disease activity and symptoms in children with demyelinating disorders. She has also started developing a mobile app and research platform to deliver a physical activity promotion program to help engage youth with demyelinating disorders in becoming more physically active.
