Philip Crain received his Ph.D. in Entomology from the University of Kentucky studying novel mosquito control strategies. After a post-doctoral research position at Westfälische-Wilhelms Universität in Münster, Germany, he joined the insect resistance management research team at DuPont Pioneer. Philip has a strong ecological background, and promotes the use of computer models to understand complex interactions. Population genetics and population dynamics models should include economic analysis if the goal is control of pests or disease.
