Research Interest

Our research currently focuses with our collaborators on mercury concentrations and stable isotope signatures in seals and sea lions and their prey to help understand how heavy metals move within ecosystems and how they may impact conservation of piscivorous marine mammal species. We also focus on assessment of diet composition using stable isotopes, body condition and general health assessment of marine wildlife, and adaptive biochemistry and metabolism in fasting marine mammals.
