Doug is a wildlife ecologist with the NOAA Fisheries Antarctic Ecosystem Research Division. His research identifies the mechanisms through which predator-prey interactions, including hunting tactics, can inform community dynamics along food webs. He currently leads NOAA’s Antarctic Pinniped Program based in La Jolla California. This program investigates the ecology and population dynamics of Antarctic seals, particularly Antarctic fur, Weddell, and leopard seals. Over the course of seventeen years, he has worked with seal populations from Norway to the California Channel Islands. However, the bulk of his work has been focused on understanding how Antarctic fur and ice seal populations are responding to a rapidly warming climate in the Antarctic Peninsula. This research supports the conservation and management of Antarctic marine living resources through the Antarctic Treaty System.
