Ecology and physiology of amphibians and reptiles

Current Projects

Physiological ecology of helodermatid lizards. Using techniques including biophysical modeling, isotopic tracers, and radio telemetry to investigate the consequences of how helodermatid lizards (Gila monsters and beaded lizards) interact with their environment. 

Digestion and physiological responses to feeding in crocodilians. Investigations into metabolism, energetic costs of digestion, nutrient absorption, and digestive enzyme activity in crocodilians.
