Ph.D., University of California-Los Angeles, 1981
B.A., Pomona College, 1976

My principal research interests are igneous petrology, tectonics, and the geologic evolution of western North America. Tools employed in these studies include field work, whole-rock geochemistry, radiogenic isotope studies, U-Pb geochronology, and structural geology.

Recent awards

I was awarded the 2011 J Carlyle Sitterson Freshman Teaching Award for my Fall 2009 First-Year Seminar entitled Field Geology of Eastern California. Many thanks to the students who made this award possible--they were the ones that did all the work that semester.
