Microbial Ecology and Epidemiology

Research in the department on Microbial Ecology focuses on biotic and abiotic mechanisms of suppression of pathogens in soils, biodiversity of plant associated fungi, nematodes, bacteria and viruses, and population structure and dynamics of plant-pathogens and other plant-associated microbes. Epidemiological research focuses on disease forecasting in multiple pathosystems, spatial and temporary epidemiology, dynamics of fungicide resistance, host resistance, and impacts of resistance on pathogen populations.
