The focus of our research is Translational Taxonomy of Bacterial Plant Pathogens.

We use taxonomic inquiry to develop management strategies for bacterial diseases of plants and cultivated mushrooms. Management strategies include biological control, host plant resistance, inoculum detection and management, and changes crop production practices (e.g., crop rotation).

We have major projects investigating bacterial disease of Lettuce, Cucurbits, Beets and Chard, Mushrooms, and Potato. We provide taxonomic expertise for researchers and stakeholders in government, academia, and industry.

Trailblazers: Carolee Bull Investigates the Microbiome

Interdisciplinary work truly defines Carolee Bull, director of Penn State's Microbiome Center and professor and department head of Plant Pathology and Environmental Microbiology. Her research centers around translational taxonomy which is the use of bacterial systematics, combined with epidemiology, and population biology of bacterial plant and mushroom pathogens and biological control agents to manage plant and mushroom diseases. Bull’s work spans some of the most pressing issues of food security, such as global seed health.
