During the past 25 years as a professional geologist, I have pursued my research in a variety of locations. Much of my field time has been spent in western North America, including several years in Nevada working on Carlin-type deposits, both in regional exploration efforts and in detailed research efforts. In addition, I was a mine geologist at Climax for two years and spent three years in Alaska doing regional exploration. Before coming to the University of Nevada, I spent three years in New Zealand studying volcanic and geothermal systems and epithermal gold deposits. Although much of my present research is geochemical in nature, it is based on fieldwork, and attempts to solve problems that were generated in the field. Understanding of field relations is of paramount importance for laboratory or experimental studies.
My primary teaching responsibilities at the University of Nevada include introductory and advanced courses in Economic Geology and Isotope Geochemistry. Two important skills I hope to embody in my teaching are communication and critical thinking, in a geological context. Critical thinking skills are necessary for sorting the useful from the non-useful, for reading others' work with a discriminating eye when comparing contrasting ideas. In my courses, I emphasize excelling in both writing and speaking skills. Finally, while it is important to direct students toward current job markets, that should not be done to the detriment of a broad general education in geology. Those who have been successful in making job transitions between different areas of geology are those who have a solid, varied background. I make all of my students aware of this, and encourage a broad education. For a more complete description of the courses in which I am involved, Click here.
My research encompasses geochemical approaches to geological problems, particularly applications of both stable and radiogenic isotope geochemistry to problems of ore deposits, petrology, and fluid-rock interaction. Dr. Simon Poulson and I are in the final stages of installation of the UNR Stable Isotope Laboratory, which will include state-of-the-art instrumentation for measuring stable isotope ratios in virtually any geological material. Much of my current research focuses on Carlin-type and epithermal mineral deposits, both in the Great Basin and worldwide. The links below provide brief descriptions of some of the research I have in various stages of progress.
