My research focuses on the systematics (the discovery of the diversity and evolutionary history of organisms) and population and evolutionary ecology of lizards, snakes, and frogs. Specifically, my laboratory investigates the phylogeography (the study of the geographical distribution of genealogical lineages) of species from the Puerto Rican Bank, in the eastern Caribbean Sea, the feeding ecology of snakes from western North America, and more recently, life history evolution of scorpions.
