I am an animal behaviorist interested in the evolution
of alternative strategies and tactics and the economics and mechanisms
of decision making in animals. In particular, I am studying the
evolution of mating and nesting behavior of horseshoe crabs. I am also
interested in sexual selection, mate choice, and paternal care, the
evolution of sex ratios, the evolution of life-history patterns (e.g.
emergence and diapause) and the evolution of social behavior (e.g.
nesting behavior of solitary and social wasps).
