Our team

(Dr) Tristan and Annie Guttridge are two of the most passionate shark advocates you could meet. Their shared love for sharks developed from childhood in England and despite having wildly different upbringing, education and experiences they were brought together by this passion, meeting and working together on Bimini - a small chain of islands in the Bahamas. As a couple they offer diverse but complimentary skills, Tristan with over a decade of experience researching shark behavior and Annie as a wildlife photographer and social media influencer. They lived in the Bahamas for 5-years, whilst Tristan directed the Bimini Sharklab, and during this time they both accumulated countless experiences with various marine animals from great hammerheads to eagle rays, juvenile lemon sharks and green turtles.

Tristan has a doctorate in behavioral ecology from the University of Leeds, UK. He has a passion for asking questions about animal behavior and has spent over a decade trying to learn more about the behavioral complexities of sharks. Why are sharks social? Can they learn from each other? Recently, Tristan has enjoyed the challenge of working with one of the earth's most enigmatic and highly mobile predators, the great hammerhead, Sphyrna mokarran. His research has revealed an important overwintering hotspot in the Bahamas and attracted global media attention. Tristan has spent thousands of hours watching sharks, interpreting their behavior and has a wealth of knowledge and experience he wishes to share!

Bryan Keller - Phd Candidate


Bryan Keller is a Ph.D. candidate at Florida State University, studying under the advisement of Dr. Dean Grubbs. Bryan’s dissertation is focused on the spatial ecology and seasonal migrations of bonnethead sharks. Dr. Guttridge served as Bryan’s advisor at the Bimini Biological Field Station, where he conducted his M.Sc. on the social behavior of juvenile lemon sharks. In 2016, Bryan traveled to Andros with Dr. Dean Grubbs to participate in research focused on the smalltooth sawfish. The team was lucky enough to discover a pregnant sawfish and assisted it in the birthing process. This was the first documented observation of any of the five species of sawfish giving birth in the wild.

Her thesis explores the factors underpinning aggregation formation of juvenile white sharks in their nursery habitat, in the Southern California Bight. She hopes to keep unraveling the mysteries of these large, charismatic species at this vulnerable, and important life stage. To go on; Emily has spent over seven years working in the research field, from assisting with both shark and ray studies, to using specialist scientific diving skills to collect data from hundreds of dive sites. Emily is hardworking, knowledgeable and incredibly passionate towards all life above and below the waves.
