Research Interests

I am broadly interested in population dynamics, community ecology, conservation biology, and marine fisheries policy. My research in applied ecology is motivated by an interest in understanding how human activities impact oceanic species and ecosystems. Much of my research focuses on sharks, from quantifying changes in their abundance to understanding their role in oceanic communities.
