Research Interests:

Paleobiology and functional morphology of vertebrates, evolution of reproductive behavior in reptiles, evolutionary biology of archosaurs, and western pond turtle (WPT) biology.

Research Program:

My current research focus is directed on fundamental aspects of western pond turtle biology, especially mechanisms of temperature dependent sex determination, population dynamics, and conservation of the species. Other areas of active research include the evolution of reproductive strategies in crocodiles, dinosaurs, and birds, and lung ventilation mechanisms of archosaurs, with particular attention on pterosaurs.
