‘Iron biogeochemistry in Lake Constance sediments’
Iron is one of the major redox elements in the Earth crust and biogeochemical cycling of iron in the environment determines the cycling of many elements (C, N, etc.), nutrients (P) and pollutants (As, organic contaminants). Respiratory pathways based on iron redox transformations are used by many microorganisms. However, it is not well understood how iron cycling is influenced by varying physicochemical conditions (i.e. fluctuating O2 or light levels, pH changes). The proposed research project is aimed at a better understanding of the complex biogeochemical iron cycle in a freshwater ecosystem. This project investigates microbial and geochemical iron transformation with the goal to provide new insights into the coupling of biotic and abiotic iron redox reactions in the environment. Geochemical analyses (i.e. use of microsensors and wet-chemical techniques), mineralogical studies (i.e. XRD, Moessbauer spectroscopy) and microbiological approaches (cultivation dependent and ind!
ependent techniques including molecular ecological analyses based on DNA and RNA techniques) will be used to study sediments from Lake Constance (Bodensee).
We offer a PhD position in an interdisciplinary, international, young and dynamic team of microbiologists, geochemists and environmental geoscientists. This position provides an opportunity to bring in the candidate’s own creativity and self-responsibility. Not only will you learn and apply various lab techniques, but you will also practice and improve your ability to discuss and present problems and results in a friendly atmosphere.
You should have a background in environmental sciences, (geo-)chemistry or microbiology and like working in a team in an interdisciplinary field. Applicants should have good communication skills and be highly motivated and committed to pursuing interdisciplinary research particularly focusing on environmental issues. Good computer and language skills (English) are advantageous. The studentship will be funded by the University of Tuebingen at TVL E13 (50%). The start date is or as soon as possible thereafter. The employment will be arranged by the administration of the University of Tuebingen. We particularly encourage female applicants to apply for this position. Disabled persons will be preferred in case of equal qualification.
