About the Project
As a partner in Geo.X, the GFZ has access to an excellent network of other geoscience institutions in Potsdam and Berlin. This largest regional concentration of geoscientific competence in Europe offers first-class cooperation and development opportunities.
In the Interface Geochemistry section, led by Prof. Liane G. Benning, we want to expand our environmental minerals team and are looking for:
PhD Fellow in Soil Environmental (Bio)Geochemistry (m/f/x)
Reference Number 4200
The research will focus on the nucleation and growth of amorphous and crystalline iron- and magnesium-phosphate phases. The main work will be based on laboratory experiments through which the kinetics, mechanisms and pathways that control the formation and transformations of phases in the Fe-Mg-P system in the absence and presence of other elements are investigated. This knowledge will help better understand modern and ancient settings where element speciation and mineral inter-transformations affect global biogeochemical cycles and/or are linked to crucial resource recovery.
You will be trained in the use of both conventional and synchrotron-based in situ and time-resolved mineral synthesis and characterization methods and techniques. You will learn how to follow and quantify the formation and transformation of mineral phases and analyse any associated changes in solution/solid chemistry. This will include mass spectrometry and UV-VIS analyses of solutions and solid phase structure and crystallinity characterization through advanced state-of-the-art scattering, diffraction and spectroscopic means using both electron and X-ray methods available in the group (e.g., PISA) or at synchrotron-facilities around the world.
The successful candidate (m/f/x) will become an integral part of the Interface Geochemistry section, work closely with other students and postdocs in the group and be registered in the PhD programme of the Freie Universität Berlin.
- perform wet lab synthesis experiments to investigate the nucleation and growth of iron phosphate or magnesium phosphate phases under simulated subsurface conditions in the presence and absence of simple organic compounds or of metals (e.g., [Me] = Co, Cu, etc)
- carry out novel, in situ and time-resolved lab experiments and phase characterizations to investigate the kinetics and pathways of these formation and transformation reactions
- determine the changes in structure, composition and size of iron phosphate or magnesium phosphate phases during their formation and subsequent transformation
- evaluate how organic compounds or metal ion adsorption or incorporation affects the stability of the formed phosphate phases
- publish in international peer-reviewed journals and present research results at scientific meetings
- MSc degree (or equivalent) in mineralogy, environmental sciences, materials or inorganic chemistry (or related fields)
- strong mineralogical or crystal chemistry background
- documented experience in the use of some analytical techniques (e.g., XRD, SEM/TEM, IR, UV-Vis, ICP-OES, IC) is an advantage
- experience in inorganic chemical or mineral synthesis is an asset
- capacity for interdisciplinary and international teamwork and excellent communication skills
- proficiency in spoken and written English
