Tracy M. Sterling
Professor and Department Head, Ph.D.
Ph.D. 1988 in Agronomy with Botany Minor, University of Wisconsin - Madison; M.S. 1985 in Horticulture, Michigan State University; B.S. 1983 in Horticulture and Agronomy, University of Minnesota. Weed physiology research centering on understanding how environmental, insect, and herbicide stresses influence crop and weed productivity. Emphasis on role of oxidative stress tolerance mechanisms in weed/crop interactions, and alkaloid biosynthesis costs for the locoweed/endophyte complex.
