Hartley George oversees the day to day running of Project Coral, the Horniman Aquarium’s ground-breaking multi-year research project, which has revolutionised the study of sexual reproduction of corals. His work centers on controlled coral spawning, larval rearing and emerging techniques such as cryopreservation, alongside the breeding of sea urchins and other marine invertebrates to support experimental and restoration-focused research. He also contributes to scientific engagement through the public aquarium, helping translate reproductive science into wider conservation impact.
