RESEARCH INTERESTS AND CURRENT EFFORTS

Ecology, epidemiology and management of diseases on vegetable crops. One of my primary objectives is to develop integrated approaches for management of Phytophthora root, crown, and fruit rot caused by Phytophthora capsici, including the use of cultural practices, host resistance, chemicals, biologicals, and other ecological and genetic manipulations. Research in my lab is also directed towards detection, identification, and analysis of genetic diversity of pathogens causing vegetable diseases.

Appointment: 100% Research

American Phytopathological Society
International Society for Molecular Plant-Microbe Interactions
Georgia Fruit & Vegetable Growers Association
Georgia Association of Plant Pathologists
Caribbean Food Crops Society
Sigma Xi, the Scientific Research Society
Gamma Sigma Delta, Honor Society of Agriculture
