Department of Plant Pathology Faculty

Faculty members study all aspects of plant pathology from the lab to field. Individual research groups focus various aspects of applied plant pathology, extension, epidemiology, forest pathology, and molecular aspects of plant microbe interactions. The department is also fortunate to include diverse USDA plant pathology researchers and UC Davis faculty affiliates from other departments, who participate in the Plant Pathology Graduate Program.
