Don Porcelli

Don Porcelli is an Associate Professor of Geochemistry at the University of Oxford, affiliated with St Anne's College. His research focuses on understanding Earth's geochemical processes, particularly through the lens of isotope geochemistry and mantle dynamics. He investigates topics such as trace metal cycling in oceanic and riverine systems, redox-sensitive elements in sediments, and the evolution of Earth's mantle through geodynamic modeling.

Key research interests include:

• Isotope Geochemistry: Cadmium, lithium, uranium, and iron isotopes in marine and terrestrial environments.
• Mantle Dynamics: Geochemical heterogeneity, mantle convection models, and the origin of Earth's volatile cycles.
• Climate and Environmental Change: Impacts of climate warming on chemical weathering in Siberian river basins and Arctic Ocean fluxes.
• Paleoceanography: Reconstructing ancient ocean conditions during events like Oceanic Anoxic Events.

His recent work explores the interplay between biogeochemical processes and microbial interactions (e.g., arsenic adsorption by biofilms) and the application of isotope tracers to trace global geochemical cycles. Collaborative projects include studies on Martian atmospheric origins and the preservation of radiogenic argon in Earth's crust.
