My research focuses on foliar pathogens including powdery mildew and Botrytis, development of disease and phenology based forecasting models, and the development of enhanced disease management practices.
Foliar pathology of horticulture crops: development of biological control systems; ecology/epidemiology of pathogens and biocontrol agents; and integrated pest management.
Research focuses on understanding the ecology of microorganisms on plant surfaces, and applying that knowledge to reduce disease development in agronomic settings while enhance the economic and sustainable production of horticultural crops. Current projects include (1) characterize the biology of foliar and fruit pathogens, particularly powdery mildews and Botrytis cinerea; (2) development of technical infrastructure for regional and national disease forecasting systems for plant diseases; (3) use of inoculum detection as a decision aid for disease management, (4) pathogen dispersion and simulation modeling
