My research investigates the ecological forces responsible for the origin and persistence of species and the evolution of differences between them in resource use, body form, and mating preferences. I am especially interested in experimental studies of natural selection in wild populations, the role of natural and sexual selection on the evolution of reproductive isolation, the effect of interactions between species on the evolution of species differences, and the genetic factors underlying divergence. I also investigate the evolution of major biodiversity gradients, such as the latitudinal gradient in species diversity.
