Research in the Browne Lab is focused on investigating patterns of change underlying organismal diversity.  We employ a multidisciplinary experimental approach to explore the relationships between genotype and phenotype from both developmental and evolutionary perspectives.  Developmental studies in the lab use three species as models; the amphipod crustacean Parhyale hawaiensis, the anthozoan cnidarian Nematostella vectensis, and the lobate ctenophore Mnemiopsis leidyi.  Evolutionary investigations include work on a range of species affiliated with these three taxa.
