Non-Tenure Track Assistant Professor, Geology
Research Interests: Paleomagnetism and geomagnetism-including the time-averaged strength of the Earth's magnetic field in Iceland, Hawaii and Norway. Developing a 3D geologic model of San Diego Co. to better understand groundwater resources in the area.
Education: B.A. Occidental College; M.S., Ph.D. University of California San Diego
