Research and/or Creative Works

Read about my recent research on Chagas vectors and their feeding habits, at, and chagasecohealth.

My research is on the evolution and ecology of host-pathogen interactions, especially population genetics of invertebrate hosts of Chagas' disease and whirling disease.

The overall questions driving my research center on understanding the ecological and genetic factors contributing to variation in infection and virulence.  My studies includes a rich assortment of topics, including host-pathogen population dynamics, vector feeding and host specificity, the evolution of virulence, and the costs of resistance and defense. These investigationsuse molecular ecology, population genetics, and complex systems modeling.
