Glen Kenny


Dr. Glen P. Kenny is a Full Professor of Physiology at the University of Ottawa and holds a University Research Chair in Environmental Physiology.  He is director of the Human and Environmental Physiology Research Unit and a Fellow of the Canadian Academy of Health Sciences.  Over the past 20 years, he has been a principal investigator of numerous human thermoregulation studies directed primarily at understanding the human heat stress response.  In addition he has led numerous randomized clinical trials evaluating exercise interventions in people with chronic disease.  His team has been conducting unique calorimeter-based research aimed at studying the physiological consequences of heat stress in at-risk subpopulations with conditions that render them particularly vulnerable to heat injury, such as aging, obesity, diabetes and related disorders.  He has authored over 290 peer-reviewed papers on human thermoregulatory control as well as physical activity and health.

Ongoing research

Dr. Kenny’s current work consists of three well-established independent yet highly interconnected directions of investigation. 

Research Focus 1. Understanding the mechanisms and controllers governing the regulation of heat loss in the human system – from the end-organ to the whole-body response.  This research is directed at understanding the mechanisms underpinning the regulation of heat loss responses (as assessed by techniques such as intra-dermal microdialysis and whole-body calorimetry) which includes how nonthermal factors associated with sensory receptor activation (baroreceptors, metaboreceptors, etc.) as well as individual factors (sex, age, acclimation, etc.) modulate the human heat stress response. 

Research Focus 2. Defining heat exposure limits for an aging workforce. This work is directed at advancing our understanding of how the worker’s health and productivity are affected by heat, in the context of industrial environments and to develop work exposure limits for heat vulnerable workers (older adults and those with chronic health disorders) which currently do not exist.  This information is been used to develop advanced solutions to mitigate and monitor heat stress in vulnerable workers.

Research Focus 3. Understanding the impact of extreme heat events on heat vulnerable individuals.  This work aims to evaluate the physiological characteristics that contribute to increased heat vulnerability by assessing the extent to which age- and diabetes-related co-morbidities such as obesity and hypertension as well as level of glucose control and diabetes-related complications may exacerbate impairments in an individual’s physiological capacity to dissipate heat.
