Eva Stueeken
Reader in the School of Earth & Environmental Sciences
Research interests include ancient nitrogen cycling, hydrothermal nutrient fluxes and redox change in deep time.
Dr Eva E. Stüeeken is a Reader in the School of Earth & Environmental Sciences and a core member of the St Andrews Centre for Exoplanet Science. Her research investigates the origin and early evolution of life on Earth and its implications for other planets, using approaches from sedimentary geology, stable-isotope geochemistry (C, N, S, Se), and transition-metal biogeochemistry. She explores key topics such as ancient nitrogen cycling, hydrothermal nutrient fluxes, and redox change in deep time. Eva has published on nitrogen fixation in the Archean, the role of brine seeps in microbial N-cycling , and transient ocean oxygenation well before the Great Oxidation Event . As PI on major projects, she is advancing our understanding of habitability through time by quantifying nutrient recycling, lightning-derived NOₓ production, and the limits of early life
