Joost Frieling

Joost Frieling is a Postdoctoral Research Assistant at the University of Oxford in the Department of Earth Sciences. His work focuses on sedimentary geochemistry, particularly mercury (Hg) behavior during thermal maturation, volcanic activity impacts on climate, and carbon cycle perturbations. He employs machine learning to isolate volcanic signatures from geological records and investigates hydrothermal events using marine sediment trace elements.

• Research Interests: Mercury cycling, Paleocene-Eocene Thermal Maximum (PETM), volcanic proxies, climate-carbon interactions, early thermal maturation.
• Key Publications: Studies on Hg volatilization during igneous intrusion events, millennial-scale Hg-hydroclimate links in Lake Bosumtwi, and marine sediment trace elements as hydrothermal indicators.
• Projects: Involved in IODP Expedition 396, analyzing mantle source conditions during Northeast Atlantic breakup and their climatic consequences.
