We are a research group united by an interest in evolutionary biology broadly, how mating systems evolve and diverge, and how these processes contribute to the formation of new species.  We study a variety of questions, including:  (1) How does speciation occur? (2) What is the genomic basis of behavioral evolution and speciation? (3) Do natural and sexual selection play a role in speciation? and (4) How do species interactions and the ecological community contribute to the process of speciation?  We study these questions using a diversity of methods and approaches, including field and lab studies of the behaviors of organisms, genetics and genomics, and phylogenetic and comparative methods. Traditionally our work has focused on the Hawaiian endemic swordtail crickets, the fastest speciating invertebrates discovered to date.
