Research Interests


My research program focuses on the diagnosis, biology, and management of pathogens affecting fruit production in Wisconsin, specifically – cranberry, apple, cherry, grape, and other specialty fruit crops. We use basic and applied research to address disease challenges of fruit production and translate these findings into practical information for stakeholders. Research projects are driven by grower needs. Research interests include fungal disease complexes, fungicide/bactericide resistance, disease forecasting, biological control, cultural and chemical management.

Goals of the UW Fruit Pathology Lab include:

  • Develop a better understanding of disease etiology and pathogen biology for current and emerging diseases
  • Study the impacts of environmental factors on pathogen populations
  • Identify cultural practices that reduce inoculum of pathogens in fruit crops
  • Develop and deploy disease forecasting systems


The Fruit Pathology Extension Program at UW-Madison serves Wisconsin growers, stakeholders, crop consultants, and allied industries by providing disease diagnostics and management solutions for diseases that threaten the productivity, sustainability, and profitability of fruit crops. We deliver educational programming through farm visits, grower meetings, field days, newsletters, social media, fact sheets, and published management guidelines.
