Evolutionary biology, phylogenetics, and conservation biology. My recent research has focused on phyloinformatic approaches for summarizing large genetic datasets, phylogenetics and phylogeography of turtles and other herps, and conservation work focused on setting statewide priorities for the management of California’s amphibians and reptiles.
