Piers Baillie Founder.

Piers is a qualified marine biologist with a first class degree from the University of Plymouth (UK). He has established a number of research, monitoring and marine conservation programs in the Gulf of Thailand, working closely with the Thai Department of Marine & Coastal Resources, as well as international post-doctorate researchers, schools and universities.

Having gained significant experience working in the tropics, Piers has developed a marine ecology and conservation program that is taught to students of all ages from around the world. He has also developed unique internships that provide a platform for individuals to engage in active marine conservation projects, giving them the knowledge, skills and opportunity to gain experience working in the underwater world.

Piers is a published author, and his textbook 'An Introduction to Corals and The Reefs They Form' is available in paperback from Amazon. He has a keen interest in educating our next generation, and has designed a program of workshops, lectures, tutorials and interactive sessions which are adapted to suit students between Reception and Year 13.


As an award winning, and featured underwater photographer, Piers is able to bring personal experiences and real-life examples into both his teaching and training programs, offering a unique insight into the field of marine conservation.

Gavin Miller Project Manager/Scientific Diving Program Director.

Gavin completed his MSc masters degree in Marine Environmental Management from the Univeristy of Exeter, where he researched whether evocative images of charismatic marine wildlife could increase individual awareness, concern, and behaviour towards plastic pollution. Having also completed a degree in Psychology, Gavin aims to combine both biological and social aspects as he pursues his career in marine conservation. His research interests also include furthering our ecological understanding of key reef-associated indicator species, as well as the development of effective local management strategies. Gavin is currently co-authoring a research paper on the relative impacts of corallivory to reefs within the Gulf of Thailand.

Dr Pauliina Ahti Post-doctoral researcher.

Pauliina has worked across the world - from sub-zero waters to tropical reefs, as a marine researcher and scientific diver. Pauliina's research interests focus on studying the ecology and evolution of fish, completing a PhD on 'The impacts of fishing and environmental stressors utilising ecological network theory'. Her work has earnt her a number of publications in scientific journals, as well as invitations to speak at conferences and workshops. Alongside her ongoing post-doctoral research, Pauliina has also worked as a dive safety officer, and is affiliated with the University of Miami.

Preeti Tak Social media manager.

Preeti holds a first-class BA in Fine Art from London Metropolitan University, focusing on participatory installations that communicate scientific findings. She believes effective communication strengthens conservation by making research accessible. She has since built a digital marketing career, working with an international PhD network, a YouTuber, and creating content for a UN convention.

Building on her love for environmental sciences, Preeti earned an MSc in Aquatic Conservation, Ecology, and Restoration at University College London (UCL) to pursue a career in aquatic species research and habitat restoration. She joined Global Reef as an intern to gain applicable research skills and is now our social media manager.
