Areas of expertise

Animal behavior, ecology, invertebrate biology, predator-prey interactions

Research interests

My work has focused mainly on predator-prey interactions, as I am perpetually fascinated by the ways organisms detect, pursue, evade, and capture one another. Spiders have served as a useful model for understanding predator-prey behavior, though I have worked with a variety of invertebrates. I am also broadly interested in sensory ecology, cannibalism, sexual selection, evolution, and the broader impacts of predation on the environment.
