Area of Expertise: 
Fitness Costs of Bt Resistance
M.S. in Entomology from Iowa State University

For her master's degree, Amanda tested whether the ecological important variables of host-plant resistance and entomopathogens could affect the magnitude and dominance of fitness costs associated with resistance to Cry3Bb1 in western corn rootworm.
