My research focuses on cetacean life history and population structure. I am particularly interested in conservation biology and how these two disciplines allow us to improve conservation plans for cetacean species by better understanding their natural history and ecology. Data collected by scientists aboard our research cruises, by observers aboard fishing vessels, and by participants in the stranding networks, contribute information about species distributions and their oceanographic habitats. These also give us tissue material to quantify life history parameters and to identify population subunits using molecular genetic tools. My research is primarily focused on understanding the:
* population structure of harbor porpoise, false killer whales and short-finned pilot whales
* population structure and ecology of common dolphins
* life history characteristics of small delphinid species
