I am a Viticulturist at the Southern Oregon Research and Extension Center (SOREC), an Assistant Professor in the Department of Horticulture at Oregon State University, and core faculty member of the Oregon Wine Research Institute (OWRI). I completed my PhD degree in Horticulture and Agronomy at UC-Davis investigating differences in drought responses among 17 red wine grape cultivars grown under several deficit irrigation regimes at the UC Kearney Agricultural Research and Extension Center. The goal of the project was to evaluate the productivity of novel red wine grape cultivars under water-limited conditions in California’s San Joaquin Valley. Since 2016, I have been stationed in the heart of Oregon’s Rogue Valley at SOREC and conduct applied viticulture research in the fields of grapevine water relations, ecophysiology, and irrigation management. I am an integral part of the viticulture team at the OWRI, whose goals are to develop sustainable vineyard management practices aimed at reducing vineyard inputs.
