Ph.D., University of Idaho, 2002
Research interests: My research and extension program focuses on how soil landscape relationships can be used to address issues related to managed ecosystems. I also serve as the liaison between the University and the USDA-NRCS Cooperative Soil Survey, pursuing ways to incorporate soil survey with research and outreach activities.
