Profile Introduction

Evolutionary and ecological impacts of behavior, including effects of predation risk on mating and sexual selection, behavioral traits associated with biological invasions, behavioral responses to human-induced rapid environmental change, and effects of behavioral syndromes (animal personalities) on social dynamics, sexual selection and parasitism.

Research Interests

Evolution and ecological impacts of behavior, including both predator-prey behavior and social/mating behavior. Special areas of interest include: ecology and evolution of behavioral syndromes, evolution of behaviors associated with ecological invasions, and social network analyses in animal behavior. Most of my work is on aquatic organisms.
