Sr. Research Associate, Department of Plant Pathology
David is a plant pathologist at Cornell AgriTech in Geneva, NY. His research has focused on pathogen ecology and epidemiology over the last 35 years in a variety of fruit crops, including apples, strawberries, and grapes. His most current research area deals with how light, both visible and UV, can be used to suppress plant diseases. He has successfully used shortwave UV to control powdery mildews and certain arthropod pests on a number of specialty crops, and is now collaborating with researchers in North America, Europe, and New Zealand to make the technology more accessible by designing practical devices for field applications, and through pairing the application technology with autonomous agricultural robots.
