The goal of my research program at Auburn is to conduct applied research and provide practical solutions that can help producers sustain agriculture in Alabama. My research program largely focuses on the areas of integrated pest management and diagnostics of economically important diseases of cotton and peanut. However, I also have other crop responsibilities including ornamentals, turfgrasses, and small grains.

My previous research at the University of Florida and North Carolina State University largely focused on plant disease diagnostics and evaluating alternative approaches for managing diseases of tomatoes. My graduate research projects focused on developing new diagnostic assays and evaluating nanomaterials for the management of bacterial spot of tomato, Xanthomonas perforans, and evaluating the effect of nanomaterials on the soil microbiome. My postdoctoral research focused on evaluating and developing new disease management strategies for bacterial spot (X. perforans), early blight of tomato (Alternaria linariae), and late blight (Phytophthora infestans) of tomato.


The goal of my extension program is to provide research-based information to producers to help sustain agriculture in Alabama. In order to do so, my extension program emphasizes on identifying and providing integrated pest management recommendations to control diseases of cotton, peanut, small grains, ornamentals, and turfgrasses.
