Research Interests

I am broadly interested in the energy, water, and thermal relations of reptiles and amphibians, particularly with respect to the physiological and behavioral responses that occur during seasonal dormancy. Two major forms of seasonal dormancy are hibernation (i.e., winter inactivity in response to decreased temperature and/or food availability) and aestivation (i.e., summer inactivity in response to extreme heat and/or aridity). Among a wide diversity of animals exhibiting hibernation and aestivation, the intrinsic ability to reduce metabolism to levels below that anticipated based on direct temperature effects alone (termed metabolic rate depression) is a hallmark of dormancy. Prior to arriving at FDU, my Ph.D. research focused on the ecophysiology of hibernation in rattlesnakes, using both field and laboratory approaches to investigate the metabolic adjustments made during the season of winter inactivity. My work at FDU will continue this general research program, using non-venomous snakes and arid-zone frogs as models of hibernation and aestivation, respectively, to improve our understanding of the factors influencing metabolic rate depression. Techniques I have used in my research program include open-flow respirometry and hygrometry, the doubly-labeled water technique for measuring field metabolic rate, and temperature-sensitive radiotelemetry.
