I am a marine ecologist whose primary expertise lies in the understanding of open-ocean and pelagic ecosystems. I am currently studying oceanic predators such as sharks and oceanic tunas, utilising mid-water baited camera technology and echosounders to inform their conservation and management strategies. As part of my research fellowship I have coordinated and lead remote field expeditions in Pitcairn, Chagos, New Caledonia, French Polynesia, Shark Bay (Australia), the Timor Sea, Palau, and the coastal Skagerrak. I have a keen interest in pelagic biogeography, biodiversity and ecosystem function. In particular, I am interested in how large scale MPAs can be utilised to further the conservation of mobile fishes and sharks.
I am fascinated by the challenges surrounding sampling and preserving the pelagic realm. The two are very much intertwined – we cannot hope to adequately protect oceanic sharks and tuna unless our decisions are informed by reliable data on their distribution and movement. I maintain close ties with the University of Western Australia, where I am an adjunct research fellow.
