My research interests span molecular evolution, phylogeography, and conservation genetics. Visit the CGAB website for a comprehensive list of Current and Past ProjectsPeople and Publications

Questions that interest me range from understanding the evolutionary processes in small isolated populations, to the use of molecular markers to infer current and historical population processes at various spatial and temporal scales. I am question driven rather than organism bound. Thus, I work with a variety of invertebrate and vertebrate taxaAs Director of the YIBS, Molecular Systematics and Conservation Genetics Center, I facilitate training in the use of molecular tools to approach a wide variety of organismal and environmentally based questions, for undergraduate and graduate students, post-doc’s and faculty.
