Office Hours

1987-1989 Postdoctoral Fellow, Princeton University
1987 PhD in Geology, U. C. Berkeley
1982 AB (with Highest Honors) in Geology, U. C. Berkeley

Prof. Renne is Director of the Berkeley Geochronology Center. His research includes applications of geochronology and
paleomagnetism to various problems in the evolution of the lithosphere, hydrosphere, atmosphere, and biosphere. Recent foci include continental flood basalts and plume-related magmatism, mass extinctions, human evolution, chronostratigraphy, tectonics, and calibration of the geologic time scale. In parallel, work on improving geochronologic methods and capabilities is ongoing. Fieldwork is principally in North and South America, and Africa, but also includes Europe and Asia.
