Research interests in our research group

 Antagonistic interactions between predators and prey are powerful evolutionary forces. Relationships between predators and prey offer classic ways of exploring adaptive evolution. Study of anti-predator traits and how predators can change ecological conditions that influence prey are questions that require integrating study of behavior, ecology, genetics, and other disciplines to understand fully the evolutionary picture. We study how the multidimensional nature of predator-prey relationships influence coevolutionary dynamics between antagonists. We are also interested in the conditions that facilitate alternative evolutionary outcomes such as polymorphism. Antagonistic interactions between predators and prey are powerful evolutionary forces.
