I am broadly interested in the evolutionary ecology of infectious disease. With disease we can study evolutionary questions on a human time-scale; we can work on problems of applied wildlife conservation as well as human health; and we integrating empirical studies with theory. In broad outline my aim is to develop a mechanistic understanding of how disease transmission is influenced by (and in turn influences) host behavior, ecology, and physiology; community composition; and evolutionary dynamics (e.g., evolution of virulence and parasite host range).
