Professor of Earth, Environmental, and Planetary Sciences


I received my Ph.D. in Geology and Geochemistry from the Massachusetts Institute of Technology in 2001. I came to Brown after three years as Lecturer at Durham University, Great Britain. I am considered a leading expert on the behavior of volatiles in the Earth's interior. My work on water in early Earth magmas is providing new insights into the thermal evolution of the Earth. Likewise, my recent research on noble gas solubility in the mantle is challenging the existing models of mantle structure and evolution.
