Peter Janiszewski has a PhD in clinical exercise physiology. He’s a medical writer/editor, a published obesity researcher, university lecturer, and an avid traveler.
Travis Saunders completed his BSc (Hon) in Kinesiology at the University of Calgary, where he was awarded the Gold Medal for the highest academic proficiency in his class. His MSc was performed at Queen’s University, and focused on the inter-relationships between physical activity, body fat distribution, and health risk in adults. His PhD studies were completed in the fall of 2013, and focused on the relationship between sedentary behaviour and metabolic risk in children and youth. After a brief Post Doctoral Fellowship at Dalhousie University examining the relationship between sedentary behaviour and health among patients with chronic diseases (cardiovascular disease, type 2 diabetes, and cancer), Travis is currently an Assistant Professor in Applied Human Science.
Throughout his graduate training, Travis was been supported by the Canadian Institutes of Health Research and the Canadian Diabetes Association. He was also the inaugural recipient of the University of Ottawa Teaching Assistant Excellence Award. His post doctoral fellowship was supported by the Heart and Stroke Foundation of Canada.
Travis is a Certified Exercise Physiologist, and a member of the Sedentary Behaviour Research Network, the Canadian Obesity Network, the American College of Sports Medicine and the Canadian Society for Exercise Physiology. He is also a former Content Editor at ResearchBlogging.org.
In his spare time Travis is a (former) competitive distance runner. He has medaled in both the Calgary and Manitoba International Marathons, and completed his first Boston Marathon in 2009. You can connect with Travis on Twitter and Google+.
