Research Interests:

My research interests lie in the interaction between exercise and the environment, particularly acclimation/acclimatization, limitations to endurance performance, and heat balance modelling. I completed a masters degree at the University of Sydney, studying sport performance in 2008. In 2009 I undertook a year-long internship at the Australian Institute of Sport in the Department of Physiology. In addition to physiological testing of athletes I assisted with research projects, including those examining the influences of altitude and heat acclimation on performance.

Since arriving at the Thermal Ergonomics Laboratory at the University of Ottawa in fall 2010, I've been involved in a few projects, including heat balance modelling in sympathectomy patients and examining the interaction between aerobic fitness and local sweat rate. My PhD thesis will focus on the interaction between heat production, body morphology (i.e. body mass, surface area), and the thermoregulatory responses to exercise.
