Research interests: "I'm interested in what drives evolution. Specifically I'm looking at the oldest known pika fossils, which are about 33 million years old, from Northern China and Mongolia. I'm investigating how, why, and when their lineage split from that of their rabbit relatives, and considering how climate changes at that time might have been related to the radiation of pikas and other mammals."

Why Berkeley: "My educational background is in geology. Given the integrative nature of paleontology, I was looking for a program based in biology. And this is the best program in the country."

Museum Involvement: "UCMP and the other Berkeley Natural History Museums (BNHM) are second to none in academic institutions, and they offer a huge advantage. I use specimens in UCMP and the MVZ for comparative studies. I've worked a lot with museum staff in the context of the Miomap project; they've got valuable expertise in databases, collections management, and integration of the Web."

Outreach: "As a first generation college student I was fortunate to have a mentor, Malcolm McKenna, who passed along his excitement for paleontology. So over the last several years I've become involved in middle and high school education, helping at-risk kids in rural Wyoming and inner-city Chicago bridge the gap to college. I have continued this work as a graduate fellow for the Exploring California Biodiversity program.”
