Hyperthermia

Our latest work (sponsored by NSERC) is on the effects of elevated body temperature on neuromuscular function and fatigue during exercise in the heat. We also have an ongoing interest in the effects of pre-cooling on exercise tolerance and the design of microclimate cooling underneath protective clothing.

Hypothermia

Our current focus (sponsored by NSERC) is on the effects of cold exposure on hand function. We also have an ongoing interest on methods of rewarming from hypothermia.

Offshore Survival

Our SafetyNet sponsored research and our close collaboration with Survival Systems in Halifax is focused on improving survival odds with sudden cold water immersion.

Thermal Stress & Cognition

A new area of research (sponsored by SafetyNet and a pending grant to CIHR) for the EEL is the effects of cold and heat stress on mental performance. This is a wide-ranging field encompassing basic psychology and also applied psychology such as navigation and lost-person behaviour.
