Research objectives:

The objectives of my current research are to develop a bioenergetic model to estimate prey requirements of northern fur seals individuals and populations using data from pelagic surveys, captive studies and literature reviews. Estimates of prey consumption are prerequisite data for further analyses of the ability of the environment to support fur seal populations, the impact of fur seals on populations of their prey, and potential competition between fur seals and fisheries.

Research interests:

I am interested in understanding how environmental changes such as prey availability, food quality or quantity, temperatures etc, affect health, life history and ultimately populations of marine mammals. I am also interested in multidisciplinary studies that integrate environmental physiology, ecology and modeling to have a broad perspective on the complexity of processes involved.
