About the Department

The Department of Plant Pathology and Environmental Microbiology engages in quality research, education, and outreach in plant pathology, mushroom science, and environmental microbiology. We study the microbiology of plants, soil, mushrooms, bats, turtles, insects, and more habitats and strive to understand the relationships between microbes, and microbes’ relationships with their hosts and the environment. We apply our fundamental research to managing diseases and solving other problems that impact food safety, crop productivity, human health, and agricultural and ecosystem sustainability.

We have a long and prestigious history of research, extension, and training in plant pathology. Trainees are attracted to our department because of our transdisciplinary approaches solving a wide array of global problems. Postdocs, graduate students, and undergraduates benefit from faculty who are involved in interdisciplinary work through Penn State’s institutes and centers. We prepare our trainees for diverse careers in academia, industry, and government through a variety of training opportunities.

Our faculty play vital roles in teaching and advising for the undergraduate Plant Sciences major, with options in Agroecology, Horticulture, and Plant Science, and advise undergraduate minor degree programs in Mushroom Science and Plant Pathology. The general education courses offered by our faculty give hundreds of students their first hands-on experience in biology and teach them to think critically, like a scientist. Seize the opportunity to make a difference as an undergraduate by working elbow to elbow with our scientific teams through our research opportunities.

Our Ph.D. program in Plant Pathology was highly ranked nationally among plant science programs by the National Research Council in 2010 and is one of the top graduate plant pathology programs in the country. We invest in individuals to help them develop into unique scientists with outstanding technical, communication, and professional skills. We provide our students with unprecedented travel, funding, and professional development experiences. 

Of our many departmental strengths, none are more valuable than our culture. Students, faculty, and staff collaborate to create top-ranked educational, research, and extension opportunities in a collegial and friendly atmosphere of mutual respect.
