Education

Ph.D.: Nebraska (1994)

Year Appointed: 1994

Rank: Associate Professor

Areas of Interest

Integrated weed management (Southern ROC, Waseca)
Research

My primary responsibilities are in the areas of biomass production and alternative cropping systems. Much of my work emphasizes applied ecology in the development of economic and environmentally sustainable farming systems. Outreach activities center on SROC special events, serving as a resource person for several organizations, and participation in Extension programs throughout the year.
