Canada Research Chair in Environmental Ergonomics
Our Environmental Ergonomics Lab (EEL) is interested in the effects of environmental stress (heat, cold air and water, hydration, altitude) on human physiology and performance. This research spans fundamental investigations into the mechanisms of human physiology, while at the same time being applied towards making work and recreation in extreme settings safer and more productive. We have worked with many partners (military, firefighters, miners, search & rescue, elite athletes, clothing manufacturers), from improving survival models, to clothing/equipment research & development, to developing hydration and heat adaptation policies.

I am passionate about the sport and science of cycling. I have competed in road, mountain bike, and cyclocross since 1986. I am heavily involved in the popularization of science, serving as a Sport Science & Training Editor for www.pezcyclingnews.com since 2002, along with co-authoring the book “Cutting-Edge Cycling” (2012) and co-editing the book “Cycling Science” (2017).
