Dr Paige Maroni is a polar and deep-sea biologist who uncovers biodiversity in Earth’s most remote environments; the Arctic, Antarctic, and deep ocean. Using genetic tools, subsea technology and ocean expeditions, she discovers new species, maps seafloor habitats, and reveals how life is connected across vast marine ecosystems. She has led voyages across the world, collaborating globally to understand and protect vulnerable species. As a science communicator, ambassador, and UN Ocean Decade Team leader, Maroni shares her discoveries with the public and policymakers, helping to drive ocean conservation and inspire future generations of scientists.
