Academic Interests

My research focuses primarily on the ecology, conservation, and life history of amphibians and reptiles, predominantly turtles and pit-vipers.  My research spans a multidisciplinary approach to understanding these foci ranging from population ecology, demographics, spatial ecology, behavior, thermal biology, physiology, population genetics, and wildlife disease. For my larger long-term projects, I integrate this multidisciplinary approach to achieve conservation goals oriented at recovery and maintaining viable populations of imperiled species.

Key Words - Conservation, Population, Spatial, Behavioral, and Community Biology of Reptiles and Amphibians.
