Academic Background

Ph.D. Plant Pathology, University of Georgia. - 2011
B.S. Agricultural Science, Tamil Nadu Agricultural University, India- 2006

Extension Interests and Current Efforts

My extension program focuses on the management of the multitude of plant diseases that affect over 20 different vegetable crops produced in Georgia. My research efforts focus on Fusarium wilt of watermelon, (Fusarium oxysporumf. sp.niveum), gummy stem blight of watermelon (S. citrulli), bacterial spot of pepper (Xanthomonas euvesicatoria), black rot of cabbage (X. campestris pv. campestris), and a complex of bacterial diseases of onion.  Research efforts include monitoring strains for fungicide resistance and gaining a better understanding on the ecology of bacterial pathogens. This information will be used to develop novel management practices ranging from the use of nanotechnology-formulated pesticides to how best fertilize plants with micronutrients that up-regulate superoxide dismutases and other enzymes associated with the systemic acquired resistance pathway in plants.
