Nigel is a leading expert on the application of chemical tracers such as stable isotopes and telemetry in the study of marine ecosystems. Nigel completed a Ph.D. at the School of Ocean Sciences, Bangor University, UK. He now has extensive experience working with marine predators, specifically sharks, skates and rays and has worked on a diversity of species in environments ranging from the ice lands of the high Arctic to the desert of the Sudanese Red Sea, Australia, The Bahamas, Mozambique, Kenya, Southern Africa, the Chagos Islands and most recently Ascension Island in the central Atlantic Ocean. Over the last 6 years he has published over 50 peer reviewed scientific papers including those in Nature, Ecology Letters and Science, with these having direct implications for fisheries management and policy. Nigel is currently an Assistant Professor at the University of Windsor, Canada and leads the Arctic program for the Global Ocean Tracking Network and the Red Sea Elasmobranch Conservation Program for the Cousteau Society. His research examines issues at the individual, community and ecosystem level and aims to provide data for effective global conservation and management strategies.
