Dr. Adam Davis is professor and head of the University of Illinois Department of Crop Sciences. He is internationally known as a scholar of agroecology, with an emphasis on ecological weed management. His research makes use of both experimental and modeling approaches to solve applied weed ecology problems in field crop production systems. Research foci include modeling the evolution and spread of herbicide resistant weeds, developing multi-tactic integrated weed management systems for organic and low-external-input farms, predicting changing distributions of weedy and invasive plant species under global change and conducting risk analysis of bioenergy crop invasion potential.
