My major research interest is the study of natural chemicals that mediate interactions between organisms and how these chemical messages affect insect behaviors, with the ultimate goal to develop practical applications for semiochemicals for integration into pest management programs while sustaining and enhancing pollination services.

I joined the Department of Entomology at the University of Wisconsin in October 2012 as the Fruit Crop Entomologist and Extension Specialist. My research program focuses on 1) developing and refining effective, economical, and environmentally sound insect pest management (IPM) strategies; 2) determining the importance of pollinators and developing strategies for conserving and enhancing pollination services for fruit crops in Wisconsin.  The focus of my extension program is to provide up to date, research-based information to Wisconsin fruit growers on effective and sustainable IPM practices and on pollination services.
