Research Interests

My research interests are in the broad topic of insect ecology. Within that context, I conduct both fundamental and applied research on a variety of arthropod taxa.  My primary fundamental interests are in the ecology and evolution of adaptive traits.  I am particularly curious about traits that are associated with choices.  This research has examined topics such as social polymorphisms, oviposition behaviors, mate choice, and host choice of parasitioids and herbivores.  My applied research generally focuses on ecologically sustainable and sound methods of managing insect pests, especially disease vectors.  In that context, I often focus on implications for Integrated Pest Management. Ideally, I strive to combine my two lines of inquiry and apply knowledge of ecological traits to develop management strategies.
