Research Interests

My field of research is Ecological and Evolutionary Physiology.  Currently, my laboratory focuses on several projects, including mechanisms and significance of biological rhythms (both daily and annual), ecology of thermoregulation, and the use of diurnal animal model for the study of depression.  Methods used in the lab span from field work to molecular methods, and we study a variety of animal species, mainly small mammals.
