Matthew Fidelibus
Extension Specialist, Department of Viticulture & Enology, UC Davis

Matthew Fidelibus is an Extension Specialist in the Department of Viticulture & Enology at UC Davis. An internationally recognized viticulturist, his research program seeks to improve the yield and quality of raisin, table, and wine grapes through rootstock and scion selection, mineral nutrition, trellis and canopy management, and the use of plant growth regulators. Currently he is working with Larry Williams, Professor of Viticulture & Enology, at UC Davis, to develop nitrogen and potassium budgets, and refine nitrogen fertilization guidelines, for table grapes. He is also testing trellis systems and management practices to optimize yield, quality, and mechanization potential for dry-on-vine raisin production.

Fidelibus received his B.S. in Biology from San Diego State University, his M.S. in Botany from Arizona State University, and his Ph.D. from the University of Florida. He joined the Department of Viticulture and Enology in 2002, and is located at the Kearney Agricultural Center, in Parlier, CA.

Fidelibus maintains an active extension program, and in 2015 was honored by the American Society of Enology and Viticulture for distinction in extension. In 2011 the Plant Growth Regulation Society of America awarded him the Young Scientist Award. He has given invited presentations on raisin, table and wine grape production to grape grower groups in Argentina, Chile, India, and Peru. He has served as an associate editor of several academic journals in viticulture and plant science.
