I am a new Assistant Professor in the Department of Evolution, Ecology, and Organismal Biology at The Ohio State University. I am an evolutionary ecologist and use a multidisciplinary approach to study the patterns and processes of diversification in mammals. Many of my questions in biology are inspired by natural history and I strive for an integrative research program that synthesizes information from molecular, ecological, and behavioral studies. I have a varied professional background in biology including both in academia and in government. I did postdoctoral research with Michael Nachman in the Department of Integrative Biology and the Museum of Vertebrate Zoology at UC Berkeley and with Adam Leaché in the Department of Biology at the University of Washington. I completed my PhD under George James Kenagy in the Department of Biology and the Burke Museum of Natural History at the University of Washington and a my MSc under Eric Gese in the Department of Fisheries and Wildlife at Utah State University.

Between my Master’s and doctoral program, I worked for 5 years for the U.S. Fish & Wildlife Service on endangered species issues in Montana and Southern California.

I also have a strong desire to improve human diversity in the biology profession. My personal experiences as a biologist in academia and government have strengthened my desire to help improve access and retention of underrepresented minorities in biology.
