Assistant Professor of Biology
I received my B.A. in Computer Science and Earth and Planetary Sciences from Johns Hopkins University in 2003 and a Ph.D. in Earth and Planetary Sciences from Harvard University in 2009. After two years as an O K Earl Postdoctoral Scholar in Geology and Postdoctoral Scholar in Geobiology at Caltech, I joined the Biology Department at Haverford in 2011 as an Environmental Biologist. I enjoy field-based work, whether geological or botanical in nature, and try to spend my summers near some combination of plants, rocks, and trout.
My lab investigates the coevolution of plants and the environment over the last 475 million years. We employ mathematical models, chemical analysis of fossils, comparative anatomy, and experimental plant physiology to reanimate extinct plants, focusing on examples with unusual anatomy, development, or growth forms. These insights shed light on past (and future) climate change, the evolutionary trajectory of plant adaptations, and ecosystem responses to mass extinctions. You can download my papers here.
