Bio
My research interests involve the biology, epidemiology, and management of diseases affecting corn, cotton, and tobacco in North Carolina. My goal is to support the needs of field crop industries in the southeastern United States by utilizing laboratory, field, and greenhouse studies to evaluate and provide science-based solutions and integrate pest management strategies for stakeholders. My primary focus is on highly destructive, soil-borne diseases of tobacco, including black shank (Phytophthora nicotianae), bacterial wilt (Ralstonia solanacearum), and target spot (Rhizoctonia solani), as well as emerging diseases in corn and cotton. In addition to my work on traditional field crops, I am exploring strawberries as an alternative crop for tobacco growers, focusing on disease management strategies for Neopestalotiopsis in strawberries to enhance sustainable production.
