Research focuses on understanding the ecology of microorganisms on plant surfaces, and applying that knowledge to reduce disease development in agronomic settings while enhancing 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) developing methods to detect and monitor airborne inoculum and use of these data as a decision aid for disease management; (3) model turbulent airflow and spore dispersion to better predict the spatial and temporal spread of a pathogen; (4) assessment and mitigation of fungicide resistance.
