I am interested in the physiology of diving in marine mammals. More specifically, I will examine the adaptations that allow them to not only survive, but also thrive in an environment that most mammals are incredibly ill-adapted for. Recently, new opportunities have emerged with breakthroughs in miniaturized accelerometer instrumentation that can be deployed on free-ranging mammals. These instruments will allow us to record and study how they move in an effort to understand how they maximize foraging efficiency through unique physiological adaptations. When combined with metabolic analysis through open-flow respirometry, we can also examine the energetic cost of both stroking and 3-dimensional maneuvering underwater.
