Broadly, I am interested in understanding the factors that affect the distribution, abundance, and persistence of wildlife populations. My primary study systems involve the conservation ecology of reptiles and amphibians. I am currently studying the ecology and habitat use of desert tortoises in the Mojave desert to understand ways to reverse their declines and mitigate negative impacts from ongoing land conversion. A different project focuses on the establishment and potential impacts of non-native watersnakes introduced to California. See my website for more information.
