Profile

Ph.D. University of California at Berkeley, 1997 (Entomology)
BS University of Illinois at Urbana-Champaign, 1991 (summa cum laude, Honors Biology)


My research group and I work broadly in the field of landscape ecology of arthropods in both agricultural and natural systems.  I am interested in understanding how enhance and conserve the services carried out by beneficial arthropods in agricultural landscapes.  In Wisconsin agricultural landscapes, we are interested in understanding how beneficial insects, such as pollinators and lady beetles, utilize the landscape and carry out important functions such as pollination of crops and suppression of insect pests.  Our work studying insect landscape ecology and conservation has partnered us Wisconsin potato, soybeans, cranberry and apple growers as well as rotational grazers.  We focus our studies on understanding how land-use and land-cover interact with management in order to develop ways to enhance and conserve beneficial insects.  I am also a project leader in the Sustainability Area of the Great Lakes Bioenergy Research Center helping to develop sustainable management of bioenergy landscapes.  In less managed systems, our research program examines the ecological linkages between lakes and land with a particular emphasis on sub-arctic lakes in Iceland.
