I am interested in understanding how the behavior of marine mammals relates to changes in their environment. I am particularly interested in the feeding behavior of baleen whales and species-specific differences in feeding strategies and how changes in prey type affect behavior. I am also keenly interested in understanding how anthropogenic disturbances (e.g. ocean noise, sonar) affect marine mammals. I have multi-disciplinary and long-term research programs using tag technology to study cetaceans in Antarctica, Alaska, California, and Cape Cod.
