The overall goal of my research is to more clearly image the structure of the Earth's crust and mantle using seismic waves in order to better understand dynamic processes inside the Earth. Our recent work has focused on two topics: the continental lithosphere and its interactions with the deeper mantle, and mantle flow and melting processes in subduction zones. These studies blend analysis of observed seismic body and surface waves - often gathered through temporary field deployments of seismic stations - with numerical modeling of mantle processes and prediction of theoretical waveforms.
I graduated with a BS in geology and geophysics from Yale in 1983 and received my PhD in geophysics from MIT in 1989. After a postdoctoral fellowship at the Lamont-Doherty Earth Observatory (Columbia University), I joined the faculty in the Department of Geological Sciences at Brown in the fall of 1990. I was a Royce Family Professor of Teaching Excellence from 2004 to 2007.
