My Extension responsibilities cover viticulture across the state, and include juice, processing, and wine grape production. I work closely with other members of the Viticulture and Enology program to help transfer knowledge gained through WSU research (and beyond) to the hands of the Washington viticulture industry. This includes the development of workshops and educational programs, publishing the WSU Viticulture and Enology Extension News, and teaching three courses in the WSU-Extension Viticulture and Enology Certificate Program.
As a general overview my program is looking at the applied science behind (i) vineyard site selection and establishment, (ii) grapevine canopy manipulation and management, and (iii) general viticulture practices on wine and juice grape production. These include validating existing and developing new site selection models and criteria for defining grape quality and ideal growing conditions, understanding how canopy manipulation and management strategies influence grapevine growth and development, and optimizing the timing and type of viticulture cultural techniques for combined impacts on disease management and grape quality.
My program is located at the Washington State University Irrigated Agriculture Research and Extension Center in Prosser, WA. WSU-IAREC is approximately 3 hours south of WSU-Pullman, and 35 minutes west of WSU-TriCities.
