Professor of Earth, Environmental, and Planetary Sciences (Research), Professor Emeritus of Geological Sciences


I received my Ph.D. in Astronomy at the University of Texas at Austin in 1972. After working as a research associate at the NASA Ames Research Center, and a Staff Scientist at The Lunar and Planetary Institute, I became an Associate Professor in the Department of Geological Sciences at Brown University in 1984. I was promoted to full Professor in 1994. In addition to my research and teaching responsibilities at Brown, I have served as Director of the Lunar and Planetary Institute Planetary Image Facility, and am currently the Director for both the Northeast Planetary Data Center and the NASA/Rhode Island University Space Grant Consortium.
