More About

I use phylogenetic methods to explore questions that lie at the intersection of ecology and evolutionary biology.

Research Interests

Phylogenetic approaches to problems in ecology and evolutionary biology, including:

  • Niche conservatism and the origins of geographic patterns of community structure
  • Systematics and evolutionary ecology of amphibians and reptiles, particularly emydid turtles
  • Vertebrate biogeography and trait evolution
  • Disease ecology
