1990: Survey Assistant, The Ohio Cooperative Extension Service, Entomology IPM

AREAS of RESPONSIBILITY in EXTENSION, RESEARCH, TEACHING

Appointment (60% Extension, 40% Research). Cultural and integrated vegetable management strategies, new commodity testing. Primary goals are to: 1) better understand mechanisms which drive vegetable crop physical, chemical, and sensory quality and 2) assist crop managers in implementing strategies which maximize crop quality, as defined by the market. Current studies, which focus on the impacts of soil nutrient level and temperature and moisture availability, help to define how vegetable crop physical characteristics, sensory properties, and nutritional value may be managed for grower and consumer benefit. Additional activities deal with equipping farmers to benefit from demographic and food consumption trends. Studies have helped to identify and overcome production and market related obstacles to profitable specialty commodity production in Ohio, including through the use of organic methods.
