Sam Purkis is a geologist and professor at the University of Miami, where he serves as the Department Chair of Marine Geosciences. He specializes in marine geology and coral reef research, with a focus on understanding how climate and environmental changes impact marine ecosystems. His research spans the use of modern and ancient reef systems to study processes like sedimentation, biodiversity patterns, and sea-level changes, often utilizing cutting-edge technologies such as satellite imagery and numerical modeling.
