I am interested in the application of ecological theory to problems of importance in entomology and natural resource management. Together with my students, I attempt to understanding the influence of landscape structure on insect ecology and management, particularly in regard to biological control of insects and weeds. I hope to use these insights to aid in the design of sustainable landscapes that promote arthropod-mediated ecosystem services such as pollination and pest suppression. I am also interested in invasive species ecology and management, and more recently in the conservation and restoration of rare species and communities. Extension My extension program focuses on invasive species ecology and management, and on the use of ecological restoration to enhance biodiversity and ecosystem services. Current areas of outreach include: the biodiversity implications of bioenergy landscapes, prairie fen and oak savanna restoration, the use of native plants to enhance ecosystem services, and conservation of the monarch butterfly.
