Meet the team

Sarah became Director of the Trust in May 2022. Working alongside the Board of Trustees she drives the vision and mission of the Trust, creating and executing the 2023-2028 strategy, as well as overseeing and implementing all aspects of the organisation’s operations.

Before joining CCT, Sarah was a Director at a social housing association, Deputy Director of the Ditchley Foundation, and had worked in various roles for the UK Foreign and Commonwealth Office and Maltese government.

She has campaigned for BirdLife and has a particular interest in small island states, seabirds (especially shearwaters), and how climate change is affecting both. She is currently pursuing ornithological studies.

Chris served in the Royal Navy for 24 years, spending two years as the British Representative in Diego Garcia (2004-2006), visiting all the outlying islands during his tenure. On the island he was heavily engaged with numerous environmental initiatives and island conservation, including the post-tsunami action plan and beach clean-up community programmes. He is now the Chief Executive of the Tennis and Rackets Association, the national governing body of Real Tennis and Rackets.

John is Professor in Marine Biology at Bangor University in Wales, UK, with particular expertise in temperate and tropical marine environments. With over 20 years of experience, he has worked in the Indian Ocean, Arabian Gulf, Central America and Asia. His current research advances techniques for coral reef monitoring. He has filmed reef transects in the Chagos Archipelago on a number of expeditions to document changes in the coral cover.

Ken is a researcher and head of the invertebrates and plants palaeobiology division at the Natural History Museum. He studies the history of coral reef ecosystems over time scales ranging from decades to tens of millions of years. Coral reefs are currently experiencing rapid change, resulting from a variety of natural and anthropogenic impacts. Documenting how reefs have responded to past environmental changes will help to constrain the potential trajectory of future changes and allow us to plan accordingly.

This work requires assembling large-scale biodiversity and ecological databases to compare ecosystem structure and function in multiple regions, such as my projects in the Coral Triangle and the Caribbean. Ken takes advantage of new advances in informatics and enjoy developing and applying the quantitative methods required to address these issues.

A chartered accountant with over 30 years’ experience, James is a member of the Institute of Chartered Accountants of England and Wales, and a graduate of the London School of Economics.

He is currently the Chief Financial Officer of a small international project and engineering company. He has previously worked in a number of finance roles – from small companies to working within listed environments – covering statutory reporting, team management, tax reporting, company secretarial, and managing government grant claims. His experience covers work in Africa, Asia and the Middle East.

James has a keen interest in conservation, training and education.

Steve is a lawyer with over 20 years of experience in the environment sector. He formerly worked for the Pew Charitable Trusts, focusing on establishing marine reserves in the South Atlantic, and is a member of the World Commission on Environmental Law.

“I am joining the board member as a community member of Chagossian descent, and hope that by doing so this will allow the community to have a voice over the future and the conservation of their homeland and the surrounding environment.”

Josh has recently submitted his PhD in Materials Engineering at Swansea University, working on solar desalination. He is a keen amateur naturalist and bird watcher, with a passion for conservation. He is a committee member of the Gower Ornithological Society, where his role is to manage their social media and oversee the smooth running of online bird talks. He is also a lead volunteer for the Saving Swansea’s Swifts project, leading public swift surveys around the county of Swansea and running their social media accounts.

Bryan’s area of expertise is the resilience and recovery of tropical coral reefs under continuing anthropogenic climate change. He specialises in the endangered brain coral, Ctenella chagius, endemic to the Chagos Archipelago, and is currently preparing an ‘Emergency Species Recovery Plan’ to ensure its survival.

He has been a friend to the Trust for many years, collaborating on research work and expeditions, contributed to Chagos News, and most recently speaking at the Trust’s Annual General Meeting this year (watch his address here: https://youtu.be/4v4-A1XXg4s?si=VSzQwSw20Le-aXlu).

A marine ecologist with expertise on sea turtles, Nicole is an Associate Professor in the Bioscience department at Swansea University, a member of the IUCN Marine Turtle Specialist Group and UK representative on the UNEP-IOSEA Marine Turtle Taskforce for the Western Indian Ocean. Nicole first visited the Chagos Archipelago in 2012 to conduct the first satellite tracking study of nesting green turtles, and has since visited the islands on >10 research expeditions to address conservation priorities for hawksbill and green turtles breeding and foraging across the Archipelago. In former roles as a conservation biologist, protected area manager and policy maker, Nicole gained a wealth of conservation experience with diverse stakeholders, producing management plans, biodiversity action plans and environmental impact assessments. Conservation charity appointments have included five years as the Chair of the Dutch Caribbean Nature Alliance.

A marine ecologist with expertise on top predator ecology and conservation, particularly marine mammals, Clare is an Associate Professor in Marine Ecology at the University of Plymouth. Clare has been working in the Chagos Archipelago since 2019, initially to understand the role of oceanography in driving predator-prey aggregations including pelagic fish and reef manta rays. Since then she has been leading the first study of cetaceans (whales and dolphins) in the Chagos Archipelago and wider Indian Ocean, which she presented at the 2025 CCT AGM: https://www.youtube.com/watch?v=u54o-q8AGT8.
