My research is focused on understanding how predator-prey interactions structure communities with a particular focus on the role of non-consumptive predator effects (“risk effects”). I am particularly interested in the role of upper trophic level marine predators in their communities and ecosystems, and how ongoing reductions in their populations are likely to impact marine communities. Recently, I have also begun investigating the importance of individual foraging specializations on mediating the ecological impacts of predators, particularly their role in transporting nutrients across ecosystem boundaries.
