Nicholas Tosca

Nicholas Tosca is a geochemist and mineralogist at the Department of Earth Sciences, University of Cambridge. His research explores the interplay between natural fluids, minerals, and environmental conditions across planetary systems, with a focus on Earth's history and Mars exploration.

• Affiliation: Department of Earth Sciences, University of Cambridge
• Key Collaborations: Leverhulme Centre for Life in the Universe, Mars 2020 Perseverance Rover mission

His work integrates theoretical, experimental, and field-based approaches to study problems such as the co-evolution of seawater and climate, prebiotic chemical synthesis, and Martian surface chemistry. Research spans biogeochemical cycles, Earth surface processes, and planetary habitability.

Recent publications highlight his expertise in aqueous geochemistry, carbonate mineralogy, and Precambrian ocean chemistry, with applications to Mars exploration and the origins of life on Earth. He supervises postgraduate research projects in these areas through the Cambridge NERC Doctoral Landscape Awards program.
