Welcome to the Gevens lab!
My research program investigates the ecology of fungus and fungus-like plant pathogens for enhanced and integrated disease management to support commercial agriculture in Wisconsin. We have three main areas of focus: management of Phytophthora species pathogenic on potato and vegetable crops in field and storage, investigating species distribution and occurrence of pathogenic Alternaria affecting potato, and development of integrated disease management programming in potato systems to reduce reliance upon soil fumigation in managing key soilborne diseases. As the University of Wisconsin Extension Potato and Vegetable Pathologist, my program supports vegetable growers by providing research-based recommendations for controlling diseases during production and in storage. My research program directly feeds into my extension work.
