After earning my PhD in anthropological archaeology from the University of Washington in 1987, I have been a research professor at DRI since 1989.  I serve as cultural resources management program leader for large multi-year programs for the Department of Energy, Department of Defense, Bureau of Land Management, and other agencies.  I have acted as PI or co-PI on numerous NSF-funded research programs in archaeology and paleoecology in the Great Basin and other areas in western North America, Mexico, and western China. I have participated as a graduate faculty member at UNR and UNLV since the early 1990s. My research specialties and interests include long-term human adaptation to drylands and montane environments, archaeobotanical analyses of prehistoric and historic remains, Quaternary paleoecology (particularly long-term climate and vegetation change), and western natural history.
