Much of my basic research focuses on the optimal expression of body temperature (i.e. thermoregulation) and
the effect those body temperatures have on organismal performance (i.e. thermal sensitivity). In this work, I use 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 my focus has shifted to small terrestrial mammals
and birds. My current interest in this field is examining how adaptive thermoregulation in endotherms will interact with a changing climate
to determine the persistence, range expansion, and basic ecology of birds and mammals.
A secondary research focus in my lab is on White-nose Syndrome, a disease that has killed millions of bats in the eastern United States. My students and I use experimental, theoretical, and modeling approaches in an attempt to understand the pathogenesis of White-nose Syndrome and to explain why so much variation exists in mortality rates between species, populations, and geographic regions. We are also heavily involved in estimating the economic and ecological impacts of losing the entire bat community of the eastern United States.
