My research centers on understanding the roles of melting, melt migration, and mantle dynamics on the long-term evolution of the interior of the Earth and other planetary bodies. This includes convective motions that give rise to largest scales of mantle overturn, that we associate with plate tectonics on the Earth, as well as smaller scales of motion associated with intraplate and plate boundary volcanism. An understanding of the physics and scaling laws governing these processes allows predictions of planetary behavior which can be compared with available observations.
I received my B.S. in Engineering and Mathematics at West Virginia University in 1967. I went on to get my M.S. in Engineering (1969) and my Ph.D. in Geophysics (1975), both from Cornell University. After completing research fellowship at Oxford University, I came to Brown University in 1977 as an Assistant Professor of Research. I teach courses related to continuum physics of the earth and planets, the physics of planetary evolution, and the application of numerical methods in geodynamics. During his time at Brown, I have held research appointments at the Lamont-Doherty Earth Observatory of Columbia University and the Scripps Institution of Oceanography at UC/San Diego. In 1990, I became full professor in the Department of Geological Sciences.
