Research Interests

I am interested in the physiological adaptations of animals to their environment, and the evolutionary processes involved in those adaptations. To understand how animals function in their environment, I examine their physiology in a comparative framework. Much of my research has focused on thermoregulation - the regulation of body temperature - in both endotherms and ectotherms.
