| Description | (any length) * | I am interested in rapid evolutionary change in wild populations caused by changes in local selective pressures. The response to local selective pressures can be constrained by gene flow from adjacent populations. To indirectly estimate gene flow I use molecular markers such as mtDNA polymorphisms and microsatellite loci. In other work we use direct sequencing of PCR fragments of mitochondrial and nuclear genes to investigate the molecular systematics of recently diverged species. My laboratory works primarily on two mollusc groups: _Littorina spp. (Gastropoda, Littorinidae) and _Dreissena spp. (Bivalvia, Dreissenidae). |
