RESEARCH OVERVIEW:

tracy

My research program in weed physiology centers on understanding how environmental, insect and herbicide stresses influence crop and weed productivity. Current research projects include determining the role of oxidative stress tolerance in protecting crops and weeds from abiotic stresses; understanding the locoweed-fungal endophyte complex; and the role of perennial brome grass as a trap-crop for wheat stem sawfly.
