I am interested in marine mammal phylogenetics and the conservation and population genetics of cetaceans within the family Delphinidae. Members of this family are known to have undergone rapid and relatively recent radiations, and as a result many phylogenetic relationships within the Delphinidae are unresolved. I am interested in combining multiple lines of evidence, such as morphology and genetics, to determine the true phylogenetic relationships of these marine taxa. My research also includes investigating relationships at the population-level to help protect and accurately manage genetically-differentiated populations of cetaceans. This is important to ensure that management stocks are conserving and protecting all biological populations in the face of both natural and anthropogenic threats.
My doctoral research involved examining populations of the common bottlenose dolphin (Tursiops truncatus) in coastal and offshore waters of the U.S. Gulf of Mexico using both mitochondrial and nuclear (microsatellites and SNPs) markers. Currently as an NRC research associate in collaboration with NOAA's National Systematics Laboratory and the Smithsonian Marine Mammal Program, I am conducting a phylogenetic investigation of the genus Lagenorhynchus through examination of skeletal morphology and molecular information from both mitochondrial and nuclear markers. Additionally, to help address requirements of the Marine Mammal Protection Act and the National Marine Fisheries Service, genetic population structure is being examined for the three Lagenorhynchus species in U.S. waters (L. acutus, L. albirostris, L. obliquidens) to help evaluate current stock delimitations and ensure that managers are successfully protecting and conserving the true biological populations that exist.
