Much of my basic research focuses on the optimal expression of body temperature (i.e. thermoregulation) under varying ecological conditions as well as the evolutionary history that has led to the patterns of thermoregulation we see today. More recently, I have been working on stress physiology and the ecological effects of that stress. I use a multitude of approaches including non-manipulative data collection under natural conditions, experimental manipulations, computer modeling, and comparative analytical techniques. Insectivorous bats have been the most common model organisms in my past research, but more recently I have expanded my research to include everything from ants to birds to elephant shrews.
I apply my basic research to address the responses of endothermic species to environmental stressors. In particular, I am interested in the responses to anthropogenic stressors, like climate change, land-use changes, disease, and light pollution. My interest in this work ranges from purely ecological (e.g., trophic interactions in human-altered landscapes and around artificial lights) to purely physiological (e.g., thermoregulatory acclimation to heat stress and metabolic functioning). I am interested in recruiting students to work on any human-related stressor in natural environments.
