A marine microbiologist, Lloyd’s research focuses on transformations of organic matter and C1 compounds in the deep marine subsurface. She uses single cell genomics to determine carbon and energy sources for the vast uncharacterized majority of marine microorganisms in hydrothermal vents, cold methane seeps, deep oceanic sediments, and coastal estuaries and bays. Lloyd has participated in six oceanographic cruises, and served as scientific leader for six coastal field expeditions. Honored as a 2015 Alfred P. Sloan Research Fellow in Ocean Sciences, Lloyd is actively involved in DCO’s field investigation “Biology meets Subduction,” helping to lead many early career scientists in a multi-disciplinary sampling expedition.
