Research Interests

Why are there so many species?

I try to answer this question by examining the factors that have influenced speciation in two of the worlds most species rich groups: East African cichlids and Hawaiian crickets. Species formation in these systems has been rapid, recent, and extensive. Yet the factor that seems to influence the rate of speciation in these groups is common to most sexually reproducing organisms. That is, organisms must choose a mate.

Methods of mate choice are nearly as varied as the species in which it occurs. In cichlid fishes and Hawaiian crickets, however, mate choice extremely similar. A male signals to a female, the female assesses the male (and probably vice versa), and the individuals mate or part.

While conceptionally simple, this complex process requires an integrative approach that examines populations, individuals, behaviors, brains, genes and epigenetic phenomenon among other factors. As a result, my research interests are varied. Currently, my work focuses on the genotype-phenotype relationship with respect to male signaling behavior and female preference.
