I'm a native of Tucson, AZ, and have been interested in reptiles since I was a kid. My career in herpetology first started just out of high school working as a reptile keeper at the Arizona-Sonora Desert Museum. I received degrees from the University of Arizona (B.S.) and The University of Texas at El Paso (M.S.), and The University of Texas at Austin (Ph.D.). I am the Curator of Herpetology at the Biodiversity Collections at The University of Texas at Austin. My job includes working with the preserved collection of 113,000 amphibian and reptile specimens at the Biodiversity Collections, participating in a variety of educational outreach programs, teaching natural history field courses at UT, and continuing my own research program. My research focuses on the biodiversity and natural history of Texas reptiles and amphibians, with current projects examining demography, habitat use, and natural history in three populations of reptiles: Nerodia erythrogaster on the University of Texas campus, Kinosternon flavescens in Jeff Davis County, and Holbrookia lacerata across the state of Texas.
