PhD Position in Cryogenic Carbonate Mineralization and Carbon Dioxide Fluxes

Join a Leading Research Initiative in Experimental Geochemistry

The Geomitigation of Greenhouse Gases group at ETH Zürich is seeking a highly motivated and innovative individual with a profound passion for low-temperature experimental geochemistry. This role is integral to a newly funded project that bridges experimental geochemistry, cryosphere science, and planetary surface processes, supported by full funding for four years with an anticipated start date of January 4, 2027.

Project Background

In this position, you will explore the impact of freezing on carbonate mineral formation and carbon dioxide exchange in environments that mimic cryogenic conditions, including glaciers, sea ice, permafrost, and ice-rich planetary systems. Your contributions will help establish a cutting-edge experimental platform for low-temperature geochemistry at ETH Zurich, delving into how ice formation influences carbon cycling in cold environments. The project will involve controlled freezing experiments, aqueous geochemistry, gas monitoring, and mineral characterization aimed at understanding the dynamics of carbon release and storage during freezing processes.

Key Responsibilities

• Lead and execute controlled cryogenic laboratory experiments utilizing customized freezing and thawing reactor systems.
• Measure and interpret geochemical data for liquids and gases using various analytical instruments (e.g., Gas analyzers, HPIC, ICP-OES, UV-Vis Spectroscopy, Potentiometric Titration).
• Recover and characterize carbonate minerals formed during freezing through mineralogical and microscopic techniques.
• Develop and parameterize a predictive kinetic framework using time-resolved geochemical measurements.
• Synthesize experimental datasets and disseminate findings via scientific publications.
• Present your research at international conferences and workshops.
• Collaborate closely with the Principal Investigator, a postdoctoral researcher, and other team members, fostering a supportive group culture.

Desired Profile

The ideal candidate will possess curiosity, diligence, and a strong motivation for experimental research. A keen interest in navigating complex geochemical systems and the enthusiasm for developing new methodologies are paramount.

• An MSc degree in geochemistry, Earth sciences, environmental chemistry, chemistry, or a related field.
• A solid interest or background in low-temperature geochemistry, water-rock interactions, mineral formation, and related areas.
• A strong motivation for hands-on laboratory work and experimental troubleshooting.
• Exceptional analytical and problem-solving skills, particularly with quantitative chemical data.
• Creativity, resilience, and the ability to work independently and collaboratively.
• Proficient spoken and written English skills.

Experience with reactive-transport/geochemical modeling is advantageous but not mandatory.

Institutional Environment

Joining our research group means becoming a part of a highly collaborative environment where creativity and open discussion are valued. You will benefit from broad expertise, excellent research infrastructure, and interdisciplinary exchange.

What We Offer

• A collaborative research environment: Engage with an enthusiastic and inclusive team dedicated to high-quality research and creative scientific thought.
• Mentorship and career development: Receive guidance from senior group members, participate in skill development programs, and engage with the broader academic community.
