He received his Ph.D. degree in evolutionary biology from Queen’s University in Kingston, Ontario, Canada, and joined UF after a Postdoctoral Fellowship at Cornell University in New York, USA. His research is focused on the population genetics of rare and endangered species and includes biogeographic and phylogeographic studies of vertebrates from microgeographic to continental scales. Recent research projects in his laboratory have included: landscape genetics of beach-adapted mice; biogeography of Central American herpetofauna; biogeographic patterns of cryptic species of west-central African crocodiles; phylogeography of fishes, small mammals, and amphibians.
