I am a marine ecologist whose primary expertise lies in the understanding of open-ocean and pelagic ecosystems. I have a keen interest in pelagic biogeography, biodiversity, ecosystem function and conservation. My PhD studies involved quantifying the influence of bathymetric features on pelagic ecology using field sampling, statistical modelling techniques, and biochemical laboratory analysis such as stable isotopes and fatty acids.
I am currently working on pelagic predators, utilizing mid-water baited camera technology to inform conservation and management strategies. As part of my research fellowship I have coordinated remote field expeditions in Pitcairn, Chagos, New Caledonia, French Polynesia, Shark Bay (Australia), the Timor Sea, and the coastal Skagerrak.
