Research Interests
I am a Professor in the School of Life Sciences at the University of Nevada, Las Vegas. My research focuses primarily on the history and future of biodiversity in western North America, with ongoing projects including: historical assembly of the warm desert biotas; phylogeography of Great Basin montane island biotas; and molecular systematics and biogeography of diverse North American rodent groups. I am a Founding Member and a Past-President of the International Biogeography Society, and an editor of the Journal of Biogeography.
