Erik A. Lehnhoff

Assistant Research Professor Ph.D., May 2008, Department of Ecology and Environmental Science, Montana State University;. M.S., 1994, Civil and Environmental Engineering, Tennessee Technological University; B.S., 1993, Civil Engineering, Clemson University. Agroecology with emphasis on ecological weed management and fitness costs of herbicide resistance in weeds; ecological impacts of invasive plant species including altered soil chemistry, effects on plant community composition, and multitrophic interactions ranging from fungi to pollinators.
