Research

As an ecologist, my research focuses on extending our understanding of how the environment, in the broadest sense of the word, can influence individuals, populations, and communities. More specifically, my research at Denison seeks to understand how human alterations of the environment can affect populations and communities, and in particular, how they are affecting amphibian populations and communities. My current research can be divided into two major project lines: 1) studies examining factors that may influence amphibian individuals, populations, and communities, and 2) studies looking at what factors may influence the distributions and abundance of terrestrial salamanders. Both project lines seek to contribute to our understanding of the basic ecology of amphibians and to our understanding of human impacts on the environment.

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 (List of Past and Current Student Researchers in my Lab).
