Research Interests

I am broadly interested in population dynamics, community ecology, conservation biology, and marine fisheries policy. My research in applied quantitative 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.

Ph.D. 2007 Dalhousie University, Halifax, Canada, Applied Ecology and Marine Conservation

M.Sc. 2002 Dalhousie University, Halifax, Canada, Applied Ecology and Marine Conservation

B.Sc. 1999 McGill University, Montreal, Canada, Biology (Ecology and Evolution)

Current Research
-Investigating consequences of overexploiting apex predators for ecosystem structure, diversity, and resilience on Pacific coral reefs through a combination of large-scale empirical analyses and field research.

-Coordinating new global population dynamics and fisheries database for commercially exploited marine fishes, and examining the global status of marine fisheries
