I was born in Carlsbad, New Mexico, and raised in a mining family. I received my BS degree in Geology from the University of California, Davis, and MS and PhD degrees in the Ore Deposits and Exploration Program, Department of Applied Earth Sciences, Stanford University.
Immediately prior to joining the faculty at the University of Arizona, I was an entrepreneur as Vice President Business Development for Specialty Product Systems. My earlier positions in industry included being an exploration geologist with WestGold and Chevron Resources, Chief Mine Geologist in the Robinson district for Magma Copper Company, Chief Geologist of Magma Copper Company, and Vice President Mineral Resources for BHP Copper. Especially in the latter two roles, I traveled extensively worldwide, including to Mexico, Peru, Chile, Australia, Papua New Guinea, Philippines, and Mongolia.
