Research interests

My work focuses on broad aspects of marine science (including behavioural, physiological and molecular ecology as well as biological oceanography) for a range of marine species including both vertebrates and invertebrates with a strong emphasis on the use of innovative marine technology and  crossdisciplinary collaboration, for example with physical oceanographers, mathematicians and physicists.

Teaching interests

I have a broad range of research students examining patterns of movement in sea turtles, climate change impacts for sea turtle nesting conditions and long-term changes in marine systems including studies on plankton, jellyfish and mega-vertebrates. Current students and research staff have field sites in the Caribbean, Indian Ocean, Mediterranean and Atlantic Islands (e.g. Cape Verde).
