David J. Gregory is Professor of Preservation of Underwater Cultural Heritage at the National Museum of Denmark and Director of the NJORD Centre for Submarine and Submerged Cultural Heritage. A trained chemist, commercial diver and an archaeological scientist, his work focuses on the preservation and long-term management of underwater archaeological sites, particularly the effects of environmental change, biological deterioration, and climate impacts on submerged cultural heritage. Over the past three decades, he has contributed to collaborative research projects in maritime archaeology, conservation science and in situ preservation. His research combines diving fieldwork, laboratory analysis, environmental science and conservation practice to develop practical approaches for assessing and preserving underwater archaeological remains. Alongside research and teaching, he has worked with museums, universities and international organisations to develop methods and guidelines for underwater cultural heritage management. He has published widely on submerged archaeological preservation and continues to work on sustainable strategies for protecting vulnerable marine heritage sites.
