Broadly, my research interests and activities are divided into two interrelated categories: learning about how grapevines grow, and learning about how to grow grapevines. In order to develop best management practices for wine grape growers, we need to understand the underlying physiological phenomena that contribute to the various aspects of wine grapes that are important. If we know more about how grapevines grow, we can ultimately grow better grapes.

Specifically, the research in my lab focuses on how abiotic stresses impact fruit yield and quality. The main stress of interest is water deficit. As a result, our studies typically involve withholding irrigation water to induce water stress. Recently, biotic stress due to viral infection has received more attention from our group as we try to understand the impacts of Grapevine Red Blotch Virus (GRBV) on vine growth and fruit quality.


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.

I accept graduate students for Horticulture
I can serve on graduate committees

Outreach and Extension

My outreach and extension activities primarily involve the organization and coordination of viticulture technical meetings in the Rogue Valley. These activities are conducted in close collaboration with the Rogue Valley Winegrowers Association and other related industry groups. In addition, I am the principal organizer of the annual Southern Oregon Grape Symposium, an all-day event that features academic seminars, grower discussion panels, research wine tastings, and field demonstrations.

Fun Fact

In theory, theory and practice are the same. In practice, they are not.
