Research Committee

Marty Hoffman, MD


Dr. Marty Hoffman is Professor of Physical Medicine & Rehabilitation at the University of California Davis, former Chief of Physical Medicine & Rehabilitation at the VA Northern California Health Care System (retired 2020), former Director of Research for the Western States Endurance Run (2006-16), former team physician for the US Biathlon Association (1988-95), and Chief Medical Officer for the Ultra Medical Team. He has published over 180 peer-reviewed publications mostly related to applied exercise physiology with focus on human locomotion, human performance and exercise-associated hyponatremia. His clinical work has involved cardiac rehabilitation, musculoskeletal medicine and sports medicine. He has been a Fellow of the American College of Sports Medicine since 1989 and serves on multiple editorial boards. He has been a competitive cross-country skier or distance runner for most of his life, and still enjoys exploring his own limits…..though at a much slower pace than in the past, and often with a fly rod.

Eric Goulet, PhD

Dr. Eric Goulet is an associate professor of exercise physiology at the Université de Sherbrooke, Canada, where he is also head of the performance, hydration and thermoregulation laboratory and director of the PhD program in Science of Physical Activity. His research interests include 1) the impact of dehydration, heat stress, ad libitum drinking and hyperhydration on physical performance, water balance and physiological functions; 2) the validation of devices or techniques aimed at measuring performance, core temperature or sodium concentration in sweat and; 3) the conduct of systematic reviews for improving our understanding of the impact of body water changes on physical performance. He is a member of the science advisory board of the Korey Stringer Institute and the Institut National du Sport du Québec. He earned his PhD in physiology from the Université de Sherbrooke and completed a 2-year postdoctoral fellowship in physiology at the McGill Nutrition and Food Science Center, McGill University, in Canada. He has published over 50 manuscripts in peer-reviewed journals, along with two book chapters. He has reviewed papers for more than 50 scientific journals. In his leisure time, he enjoys running, cycling and swimming and has completed over 50 long-distance triathlons.

Kristin Stuempfle, PhD

Dr. Kristin Stuempfle is Chief of Staff and Strategic Advisor to the President, and Professor of Health Sciences at Gettysburg College in Gettysburg, PA. She has been a fellow in the American College of Sports Medicine since 2004. Her research interests include examining the physiological challenges of ultra-endurance running. More specifically, she is interested in hyponatremia, gastrointestinal distress, and the food and fluid needs of ultramarathon runners.
