PhD Position in Cryogenic Carbonate Mineralization and Carbon Dioxide Fluxes

Lead and execute controlled cryogenic laboratory experiments using customized freezing and thawing reactor systems. Measure and interpret liquid and gas geochemical data using a variety of analytical instrumentation (e.g., Gas analyzers, HPIC, ICP-OES, UVVis-Spectroscopy, Potentiometric Titration). Recover and characterize carbonate minerals formed during freezing using mineralogical and microscopic technique. Develop and parameterize a predictive kinetic framework using time-resolved geochemical measurements. Synthesize experimental datasets and disseminate findings through scientific manuscripts. Present your research at international conferences and workshops. Collaborate closely with the Principal Investigator, a postdoctoral researcher, and other group members while contributing to a supportive and communicative group culture.

The Geomitigation of Greenhouse Gases group at ETH Zürich is actively recruiting a highly motivated and creative PhD candidate with a strong interest in low temperature experimental geochemistry. The position is part of a newly funded project at the intersection of experimental geochemistry, cryosphere science, and planetary surface processes. ETH Zurich is one of the world’s leading universities specialising in science and technology. We are renowned for our excellent education, cutting-edge fundamental research and direct transfer of new knowledge into society.
