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


I received my BA from Carleton College in 1964, then went on to get both my MS (1967) and PhD (1971) from UCLA. I came to Brown University in 1970 and was promoted to full Professor in the Department of Geological Sciences in 1989. Though officially retired as of 2005, I am still extremely active within the department.
