Short Bio
The goal of my program at Auburn University is to provide practical solutions to help producers mitigate disease losses in Alabama as well as the southeastern U.S. Research efforts focus on developing and evaluating integrated pest management strategies for diseases of cotton, peanut, small grains, and turfgrass. I leverage and utilize these research efforts to develop an effective, regionally and nationally recognized Extension program in cotton, peanuts, small grains and forages, ornamentals, and turf. My extension program provides diagnostic support and research-based integrated disease management recommendations to stakeholders.More bio information
