Research in the Weisrock Lab combines genetics, genomics, and evolutionary biology. Much of our research centers on using genetics to resolve the geographic boundaries of species in nature, reconstruct the relationships among these lineages, and address the mechanisms that have led to their formation. At the population level our research seeks to understand the adaptive and non-adaptive factors that influence gene flow and drive speciation. At a more macroevolutionary level we use phylogenetic approaches to resolve the evolutionary history of species assemblages and infer the rates at which they form.
