Associate Professor

Extension and Applied Research
My Extension and applied research program centers on improving the efficiency and sustainability of the ranching industry in eastern Oregon.  Ongoing efforts include 1) training and assisting ranchers and public land management agency partners in the development and maintenance of cooperative rangeland and grazing monitoring programs, 2) developing various electronic tools that aid ranchers in collecting, organizing, and evaluating cattle and grazing records, 3) engaging with diverse stakeholders to develop collaborative approaches to addressing complex natural resource and wildlife management issues, and 4) developing science-based tools and strategies for functional restoration of rangelands and wetlands that have been degraded by invasive plants.
