He is a Fellow of the Canadian Academy of Health Sciences and the American College of Sports Medicine and is director of the Human and Environmental Physiology Research Unit (HEPRU). Over the past 27 years, Dr. Kenny has been a principal investigator of numerous large projects directed primarily at understanding the human heat stress response. His work (funded by CIHR, NSERC, Health Canada, Government of Ontario, Ontario Centers of Excellence, Mitacs and others) is unique in that it employs the world’s only direct calorimeter (a device for making very precise measurements of body heat exchange) to assess the physiological consequences of heat stress under a wide array of environmental conditions in different population groups including elite athletes, warfighters, first responders, workers, individuals with chronic disease (i.e., diabetes, hypertension, obesity), burn patients, elderly and others. His work has been instrumental in creating new and advanced knowledge, policies, standards and guidelines for physical activity and work in hot environments that includes exposure limits, hydration requirements, clothing systems, cooling interventions, heat management strategies that include advanced monitoring technologies, and others. In addition, he has led numerous randomized clinical trials evaluating exercise interventions in managing the health and fitness of individuals including heat-vulnerable workers. He has authored over 450 peer-reviewed papers on human thermoregulation as well as physical activity and health.
