I am a herpetologist interested in the biodiversity, systematics, and conservation of amphibians and reptiles. I am especially interested in patterns and processes of speciation, and the long-standing questions of what is a species and how do we recognize it?
I use molecular data and tools from the fields of systematics and phylogeography to delineate boundaries within complexes of ‘cryptic species’ (two or more species erroneously classified as single species). My research has shown that many geographically widespread ‘species’ actually contain multiple, divergent, and sometimes sympatric evolutionary lineages that I hypothesize to be distinct species. These findings have implications for biogeography, community ecology, and conservation, and raise questions on how these sympatric lineages originated and are maintained.
As a museum herpetologist, I also devote considerable time to preparing species descriptions and taxonomic revisions, usually initiated by findings in my field collections. I have maintained an active field program in Southeast Asia since 1998, with a focus on the countries of Laos, Cambodia, Vietnam and Thailand. More recently, I have also been working in Gabon, central Africa.
Closer to home in North Carolina, I am investigating the taxonomic status of an unusual population of the Two-lined Salamander (genus Eurycea), and hybridization between native and invasive slider turtles (Trachemys scripta).
