Research Interests

I am generally interested in the ecology and conservation of sharks and have studied these animals in various regions around the world, including Australia, French Polynesia, the Red Sea and The Bahamas. Overall, my research aims at integrating mutually supportive approaches, across various disciplines to better understand and conserve shark populations. The areas of my expertise include shark movement ecology (satellite and acoustic tagging and tracking), sensory biology, population genetics, and shark fisheries.
