In addition to being a Professor in the Section of Integrative Biology, I am also Curator of Herpetology at the Texas Memorial Museum. My general research interests include the evolution and systematics of amphibians and reptiles. More specifically, my work focuses on the phylogeny of various groups of amphibians and what those phylogenies tell us about evolution.
Some general research topics by myself and those in the lab include
- Evolution of aposematism in poison frogs (Dendrobatidae)
- Higher-level phylogeny of frogs
- Phylogenetic signal in the acoustic communication systems of frogs (including Physalaemus, Pseudacris and Bufo boreas group)
- Phylogeography in the genus Pseudacris (and some other taxa)
- Mimicry and predator avoidance in the Australian froglet Crinia signifera
- Biogeography of South America, including the Andes, Venezuelan tepuis, and Amazonia
- Emerging diseases of amphibians
