David W. Sparks

Assistant Professor in the Department of Geology & Geophysics.

I'm studying dynamic processes in the earth's mantle and crust, including solid-state convection, melting, melt flow, fault zone evolution, and flow of unconsolidated materials

You can get more details on some of this stuff from my publications list.
