- M.S. Land Resources, University of Wisconsin-Madison, 1996
My research focuses on organic retailing and marketing, small farm and direct marketing, urban farming, as well as local food systems. I am also currently involved in research that examines access to local, organic, and healthy foods.
No extension appointment. I do collaborate with Extension staff on specific projects, and work with other universities and non-governmental organizations on my research areas.
