Research Interests 

Weed ecology and management; selection, persistence, and spread of herbicide-resistant weeds; mechanisms of herbicide resistance. Current research focuses on weed community dynamics and suppression in Kernza® intermediate wheatgrass (Thinopyrum intermedium) systems. Herbicide resistance research focuses on giant ragweed (Ambrosia trifida), common waterhemp (Amaranthus tuberculatus), and Palmer amaranth (Amaranthus palmeri) in Wisconsin.  

Teaching Interests 

Classroom teaching includes Agronomy 300 Cropping Systems, which addresses environmental impacts, productivity, and profitability of Midwest crop production systems. An agroecological approach, the application of ecological concepts and principles to better understand cropping system services and tradeoffs, is emphasized. Specific topics include agricultural intensification, agroecosystem structure and function, aspects of technology adoption, soil erosion and conservation, tillage systems, weed ecology and management, nutrient dynamics and management, water quality, crop rotation, and cropping system diversification.
