Beschreibung

The research group, led by Prof. Kerstin Hockmann, integrates applied and environmental geochemistry to study the geochemical cycling of elements in soils, sediments, and surface waters. Using an interdisciplinary approach, we investigate (bio)geochemical processes involving key elements such as iron, carbon, and sulfur, and their impact on trace element mobility and mineral properties in environments affected by human activity and climate change.

Your role and impact:

• Initiate, conduct, and (co-)supervise innovative research projects, including the acquisition of third-party funding for independent research.
• Apply and develop novel analytical approaches to investigate (bio)geochemical processes in both field and laboratory settings.
• Supervise and mentor students in the laboratory in close collaboration with our lab manager.
• Contribute to teaching in the B.Sc. and M.Sc. programs at the Institute of Earth and Environmental Sciences, including laboratory courses and field excursions.

The role provides an excellent opportunity to strengthen your independent research profile within a dynamic and growing research team, with the freedom to pursue your own research ideas and the support needed to secure follow-up funding. You will have the opportunity to present your research at international conferences, contribute to the supervision of PhD, M.Sc., and B.Sc. students, and benefit from tailored mentoring to advance your scientific career.

Your profile:

The candidate must hold a qualified PhD in(bio)geochemistry, environmental chemistry, geomicrobiology, organic geochemistry, or a related field, and has an intellectual curiosity about the many interdisciplinary aspects of environmental geochemistry. Our laboratory is equipped with state-of-the-art analytical instrumentation for water and environmental analyses, and we have a strong track record in applying synchrotron-based spectroscopic techniques. A passion in developing new methods and applying analytical approaches in the laboratory, along with the willingness to collaborate with researchers from diverse backgrounds in a highly interdisciplinary faculty is required. Proficiency in written and spoken English is essential, with German considered an asset.
