Research Interests

I mainly study the ecology and systematics of herpetofaunal species. I use both DNA and morphology to hypothesize phylogenetic relationships. I have also been studying biological invasions in Florida since 1992. In 2001, biologists with the Florida Fish and Wildlife Conservation Commission (FWC) and students from UF have joined my team to document extirpated and newly introduced exotic species along with their geographic distributions and ecological effects on native species. In 2011, in collaboration with FWC, we produced the first Atlas of Amphibians and Reptiles in Florida.
