   Program Overview

My program specializes in the epidemiology, biology, and control of fruit and vegetable diseases with emphasis on the development of decision support systems ranging from simple models of disease to sophisticated simulation models. Investigations often focus on the role of the abiotic environment on disease development and management including the application of new weather forecasting and information management techniques. Special emphasis has been place on surface wetness duration theory and measurement. Recent research activities include the refinement of DMCast, a forecast model for grape downy mildew based on studies defining ontogenic resistance and spore viability. A mesoscale weather forecast model is also being enhanced to allow for regional estimates of disease risk at a spatial resolution of 200-300 m.

My extension activities are in agriculture-and technology-based economic development (ATED), and are designed to assist communities, institutions, and businesses as they venture forward with new business opportunities in agriculture and related technologies.  The program is divided between outreach to communities that want to use ATED to reform or strengthen their local economy, and outreach to college and university faculty who will learn about and potentially contribute their knowledge and skill to ATED.
