He worked for the Lawrence Livermore National Laboratory for 5 years as a project scientist on uranium geochemistry, hydrothermal alteration experiments on porphyry ores, and exploration geochemistry. He joined the U.S. Geological Survey in 1978, where he worked for more than 34 years. He held a High Level CNRS Visiting Scientist at the University of Paris VI, Gledden Research Fellow at the University of Western Australia. He is currently a Research Professor at the Colorado School of Mines, Guest Professor at China University of Geoscience and consultant to the minerals industry.
