My research focuses on the ecology, behavior, and behavioral ecology of terrestrial animals. The majority of my work has been on reptiles, and my dissertation examined the ecology of the zebra-tailed lizard (Callisaurus draconoides) in the Mojave and Colorado deserts of Joshua Tree National Park, in Southern California. Specifically, I examined the diets of the lizards, and found that they consume a very wide variety of arthropod and plant taxa and also a great range of prey sizes. I also collected data on home ranges of all the individual lizards in my study and found that males and females share space differently, with males overlapping more females and with fewer males than females do. The topography of the study site also appears to play a role in how much overlap is observed between individual home ranges.
