Research

Overview 
Amphibian Ecologist — Ecology of amphibians and reptiles, especially how human alterations of the environment affect individuals and communities.
Details 

Broadly speaking, my research lies within the realm of ecology. In particular, I am interested in how individuals, populations, and communities are affected by their interactions with their environment, both the living and physical components. Much of my research program focuses on these questions as they pertain to reptiles and amphibians, and so some would identify me as a herpetologist. My research program also has become increasingly concerned with understanding how anthropogenic, or human-induced, alterations of the environment influence amphibians and reptiles. I am especially interested in examining how the introduction of non-native species and chemical pollutants affect amphibian and reptile individuals and communities.

I also collaborate with a colleague at the Universidad Nacional Autonomia de Mexico to study the ecology of Mexican reptiles and amphibians, and with a colleague at Earlham College (John Iverson) to study the ecology of turtles in Dewart Lake in northern Indiana and iguanas in Bahamas. I am very interested in including students in my research.
