Dr. Estelle Crochelet | Biodiversity and conservation | Best Researcher Award 

Scientific Director | University of Reunion Island | Reunion 

Dr. Estelle Crochelet’s research focuses on marine ecology, biodiversity conservation, and sustainable management of tropical and island ecosystems in the Western Indian Ocean. As a Marine Ecologist at the Biodiversity Research Agency of Réunion Island (ARBRE), she integrates field ecology, molecular analysis, and spatial modeling to study coral reef systems, mesophotic ecosystems, and species connectivity. Her pioneering application of environmental DNA (eDNA) techniques has transformed biodiversity monitoring by enabling the detection of rare and cryptic species such as sharks and rays, advancing ecosystem-based management and conservation planning. Through leadership roles in major initiatives including the IRRAE, MAEO, and CONCILIER programs, Dr. Crochelet has contributed to integrated coral reef management, linking ecological research with territorial planning and policy implementation. Her interdisciplinary work, combining marine biology, remote sensing, and ecological modeling, has generated valuable insights into habitat connectivity, reef resilience, and marine spatial planning. Collaborating with organizations such as IUCN, IRD, and the French Biodiversity Office, she has played a vital role in shaping regional conservation strategies and advancing scientific understanding of marine ecosystems. Widely published in prestigious journals such as Nature, Science, Environmental DNA, and Deep Sea Research, Dr. Crochelet’s work has global relevance, addressing the challenges of biodiversity loss and climate impacts on marine environments. Alongside her scientific achievements, she mentors emerging researchers, leads citizen science initiatives, and promotes public awareness of ocean conservation. A certified professional diver, rebreather user, and drone pilot, she combines technical field expertise with innovative research approaches, making significant contributions to sustainable marine governance and biodiversity preservation in the Southwestern Indian Ocean.
