Dr. Harris possesses 30 years of experience working on the physiology, genetics, molecular biology, cell biology, and genomics of yeasts and filamentous fungi. As an independent investigator, his research program has sought to understand the mechanisms underlying hyphal morphogenesis, primarily in the model filamentous fungus Aspergillus nidulans. More recent efforts have focused on investigating the coordination of growth and stress responses with morphogenesis in Aspergillus, as well characterization of adaptations that enable fungi to colonize extreme environments.
