Research

We are interested in understanding how the underlying mechanisms of the environment-physiology interaction serve to shape the distribution and abundance of organisms. In order to address my questions, we adopt an integrative approach that utilizes the tools from physiology, ecology, morphology, behavior, evolution, and statistics. We use a variety of field and laboratory techniques in our research.
How an organism allocates time and energy under varying environmental conditions and how the environment influences hormonal cycles are central themes in our research. The main study organisms are snakes (particularly pit vipers in the genera Agkistrodon [cottonmouths, cantils, copperheads] and Crotalus/Sistrurus [rattlesnakes] and water snakes in the genus Nerodia). We also have interests in the other reptiles, amphibians, and several invertebrate groups (arachnids, cockroaches, and slugs).


We broadly divide my work into two groups (eco-phys and ecology/behavior). Some of the projects that we am currently investigating with the invaluable collaboration of students and colleagues include energetic and hormonal responses to osmoregulation in water snakes, energy allocations and thermal biology in scorpions and cockroaches, digestion and nutrition in snakes, testosterone cycles in montane rattlesnakes in Nuevo Leon, and fossorial snake ecology.
