Drew Harner

Drew Harner is an Assistant Professor of Viticulture and Extension Specialist at Virginia Polytechnic Institute and State University, affiliated with the School of Plant and Environmental Sciences. His appointment is 50% research and 50% extension, based at the AHS Jr. Agricultural Research and Extension Center in Winchester, VA. He contributes to both academic knowledge and practical grower support in viticulture.

Education:

• Ph.D. in Horticulture, The Pennsylvania State University, 2022
• M.S. in Horticulture, The Pennsylvania State University, 2019
• B.S. in Viticulture and Plant Science, Cornell University, 2016

His research focuses on grapevine ecophysiology, fruit chemical composition, and sustainable viticulture under variable environmental and biotic stressors. He investigates how vineyard conditions and management practices affect grape quality and plant health, particularly in Virginia and the Mid-Atlantic. His work integrates field and lab methods, including metabolomics and physiological measurements.

The recent publications highlight a strong trend in studying stress responses in grapevines, especially from invasive pests like the Spotted Lanternfly, and how viticultural practices such as leaf removal influence grape and wine quality. There is a consistent focus on cultivar-specific responses and environmental interactions, reflecting a systems-based approach to viticulture science.

Drew Harner actively advises and collaborates with interdisciplinary teams, though no formal students are listed. His extension efforts involve grants and outreach programs through Virginia Cooperative Extension, delivering workshops, webinars, and technical meetings to support grape growers. He collaborates with pathologists, entomologists, and food scientists to enhance vineyard ecosystem understanding.

He is involved in research projects assessing microclimate effects on grape volatiles, nutrient management strategies, and the impacts of invasive species on grapevine biology. His work is conducted in collaboration with regional industry stakeholders and academic partners, aiming to improve sustainable wine grape production.
