I study marine ecological and evolutionary processes such as dispersal, speciation, and adaptive radiation using a suite of complementary approaches including molecular population genetics, simulations, behavioral observations, and experiments. During the last few years I have been using coral reef fishes in the genus Hypoplectrus (hamlets) as a model system. Adopting a fresh perspective from economics matching theory, I address the role played by sexual selection in the process of speciation with gene flow and for the long-term coexistence of ecologically equivalent species. I am also leading a large-scale genome scan of the hamlets using RAD (restriction-site associated DNA) tags to explore the genomic architecture of speciation in this group. For more information on the research of our group, please refer to my webpage.
