Marin Talbot Brewer completed the requirements for a Ph.D. degree in the Department of Plant Pathology and Plant-Microbe Biology at Cornell University in 2011. She conducted her Ph.D. research in Michael Milgroom's program, with a focus on the population genetics and phylogeography of the grape powdery mildew fungus, Erysiphe necator. Using multilocus sequencing, Marin demonstrated that E. necator populations in the eastern US are highly diverse and are a likely source for introductions of E. necator into Europe, Australia and the west coast of the US. She also identified mating-type genes in E. necator and several other powdery mildew species, including Blumeria graminis, Podosphaera spp., and Microsphaera syringae. Marin received awards from the American Society of Enology and Viticulture, American Wine Society Educational Foundation, the Mycological Society of America, and an APS Travel award. Marin is currently an Assistant Professor in the Department of Plant Pathology at the University of Georgia, Athens, specializing in fungal biology.
