My current research encompasses three areas: a) environmental biology of reptiles and amphibians; b) ecology of invading organisms; and c) the evolution of behavior. Each area involves student research assistants and collaboration with colleagues from other universities and from state and federal agencies.

I am studying the effects of human environmental disturbances and urbanization on the distributions of reptiles and amphibians. At present, this project involves extensive field work in central New York and at Onondaga Lake in particular. The Onondaga Lake ecosystem, which lies at the edge of the city of Syracuse, supports interesting herpetofaunal populations despite extensive pollution and habitat modification. How these species can tolerate this extreme environment requires much further study.

From a conservation biology perspective, I am also studying the ecology of the invading terrestrial flatworm, Bipalium adventitium. This turbellarian is believed to have been brought into the US accidentally over the last 60 years. It feeds voraciously on local earthworms and, hence, may damage both agricultural and native forest systems. My students and I, using field and laboratory studies, are examining the distribution, spread, and ecological roles of this exotic flatworm.

Using both phylogenetic and ecological approaches, I have been investigating how behavior evolves. Behavioral traits, like morphological and physiological traits, are the products of complex interactions of evolutionary, ontological, and environmental factors. My interest in this area combines experimental and theoretical analyses of both behavioral homology and evolutionary transitions in the behavior of organisms of all kinds (including humans). My experimental work has focused on the defensive behavior of salamanders.

I am also co-founder (with Matt Chapman) of the Cortland Herpetology Connection, a program which supports student involvement in herpetofaunal conservation efforts.
