Biography

I am a viticulturist at the Southern Oregon Research and Extension Center and assistant professor in the Department of Horticulture at Oregon State University. I am also a core faculty member of the Oregon Wine Research Institute, and serve as the chair of the Grape Genetics, Physiology and Management working group in the International Society for Horticultural Science.

I completed my Ph.D. in Horticulture and Agronomy at UC-Davis investigating physiological differences in drought responses among several red wine grape cultivars. Since 2016, I have been leading the Southern Oregon viticulture research and extension program at SOREC, located in the heart of the Rogue Valley near Medford, OR. I conduct applied viticultural research focused in the fields of grapevine water relations and ecophysiology, and vineyard irrigation management. My ultimate research goals are to develop sustainable vineyard management practices tailored to production goals.
