Postdoctoral Research Associate

My current research projects are focused on characterization of field-evolved Bt resistance in western corn rootworm (WCR) (Diabrotica virgifera virgifera). I am involved in monitoring and quantifying evolution of Bt-resistance and cross-resistance (for Cry3Bb1, mCry3A, and Cry34/35Ab) in WCR field populations from various locations in Iowa. We use single plant bioassays, seedling mat bioassays, diet bioassays and field experiments to measure Bt resistance.

I conduct field trials testing both commercial and pre-commercial products for management of insect pests of corn.  Much of my work focuses on western and northern corn rootworm, but I also have studied products targeting corn earworm, European corn borer, fall armyworm, seedcorn maggot and wireworm.  I conduct trials on Iowa State University Research farms and in farmers' fields.
