Dorrell William Kirby Professor, Senior Associate Dean for Faculty Affairs, and Professor, by courtesy, of Biology

I received my B.A. in Geosciences from Williams College in 1997. After graduation, I spent two years working as a high school math and science teacher. I then returned to graduate school, earning my Ph.D. in Earth and Planetary Sciences from Harvard University in the spring of 2005. Following a post-doctoral fellowship at Penn State, I joined the faculty at Stanford University in the fall of 2005. My research addresses the relationship between environmental change and biological evolution in the fossil record, with a focus on mass extinction events and long-term trends in the ecological structure of marine ecosystems. I teach courses for undergraduates in historical geology and invertebrate paleobiology and courses for graduate students in carbonate sedimentology, geobiology, and paleobiology.

I am interested in the coevolution of marine invertebrates and their environment, especially in relation to mass extinctions.

My current research interests center around two different areas: (i) Carbonate sedimentology and geochemistry, including using clumped isotopes and other geochemical proxies to unravel the source of diagenetic fluids and degree of fluid-rock interaction; and (ii) Exploring the applications and limitations of deep learning-based visual recognition techniques in carbonate geosciences.

I am interested in the evolution of insect morphology and ecology in deep time. I occasionally also study ticks, amphibians, and plants.
