Dr. Kasson received his Ph.D. in Plant Pathology from the Pennsylvania State University where his research focused on using a native fungus, Verticillium nonalfalfae, as a biological control of the invasive tree, Ailanthus altissima (tree-of-heaven). He also holds an A.A.S. from Paul Smiths College and a B.S. and M.S. from the University of Maine. His current research areas include fungal-arthropod interactions, biological control of invasive plants and pathogens, and the biology and ecology of historic and emerging canker diseases of forest trees. Dr. Kasson is currently the director of the International Culture Collection of (Vesicular) Arbuscular Mycorrhizal Fungi (INVAM) and currently has research focused on the metabolites associated with interactions between arbuscular mycorrhizal fungi and their plant partners. Dr. Kasson teaches undergraduate courses on general plant pathology and forest pest management, and offers special topics courses for graduate students including advanced plant disease diagnostics.
