George Newcombe received a Bachelor of Science in Plant Science from McGill University in 1983 and holds a doctorate in Botany from the University of Guelph. George moved from his native Canada to the United States in 1991. Today, his research encompasses plant and forest pathology and invasion biology; he is especially interested in the roles of fungi in plant communities. Here are four specific areas of application of his research: 1) diagnosis of fungi that are new to North America or to the region, 2) research on fungi that might protect native trees from exotic pathogens, 3) research on fungi that might be used against invasive plants, and 4) research on genes for resistance to exotic pathogens of plants.
