Penn State Plant Pathology and Environmental Microbiology is a tight-knit community of faculty, staff, and students united by our passion for exploring microorganisms and improving health and sustainability. We work to advance the science of plant diseases, understand infection processes and the mechanisms of disease and host resistance, and identify environmental and nutritional factors influencing plant health.
