He develops non-invasive optical and chemical tools that unlock corals’ complex metabolism, applying these to reef systems across the world to resolve how, when and where corals bleach. He also leads the Coral Nurture Program, a world-first partnership between research and tourism pioneering a new approach to reef stewardship by local communities. Since being established in 2018 on the Great Barrier Reef, the programme has installed over 100 coral nurseries and re-planted over 75,000 corals to boost natural recovery rates.
