My areas of interest pertain to the conservation and population biology of marine megafauna, particularly cetaceans. More specifically, I am interested in using both genetic and endocrinological techniques to assess population demographics and how these demographics respond at both the individual and population-level due to both natural and unnatural forcings within their environment. Populations of humpback whales in the Southern Hemisphere are recovering after intense commercial whaling during the last century. Along the Western Antarctic Peninsula (WAP) this recovery is occurring in an environment that is experiencing the fastest warming of any region on the planet. For my Ph.D. research, I hope to assess vital demographic parameters such as growth, pregnancy, and calving rates, across both the WAP population of humpbacks and compare this to other populations within the Southern Hemisphere. Lastly, once these demographics are established I hope to develop a current estimate of abundance for the WAP population and assess the impacts of climatic change on the recovery of this population.  My current work is part of the NSF Long Term Ecological Research Program at Palmer Station Antarctica.
