Postdoctoral Position - 2 years:
Heavy stable isotopes in the Earth's interior


Within the framework of an ERC Starting Grant, the Isotope Geochemistry Group of the University of Tuebingen has a vacancy for one

Postdoctoral position (TV-L E13 100%)

We are interested in the interaction between different reservoirs of our planet that led to the redox contrast between Earth's surface and its interior using volatile element systematics. Particularly important is to understand how factors such as plate tectonics, mantle melting, volcanism and continent formation contributed to or controlled atmospheric evolution throughout Earth's geological history. The postdoctoral scientist will be part of a team that investigates the link between redox changes on the Earth's surface and recycling-related evolution of mantle petrogenesis, as preserved in the stable isotope record of mantle derived minerals through geological time. To address these issues, the project combines magmatic petrology, (micro-scale) mineralogy of highly siderophile and volatile elements, Re-Os geochronology and "non-traditional" stable isotope geochemistry.

The Department of Geosciences houses a JEOL 8900 electron microprobe, Raman and IR spectroscopy, and XRF and XRD instruments for sample characterization. The isotope geochemistry group chaired by Prof. Ronny Schoenberg maintains gas-IR-mass spectrometers (MAT DeltaPlus XL and MAT 252) for H-C-O-S stable isotope analyses and a newly upgraded solid source thermal ionization mass spectrometer (MAT 262) for radiogenic Sr and Nd isotope analyses. This group also hosts new state-of-the-art clean laboratories and analytical instruments including a quadrupole ICP-MS, a Resonetics Resolution M-50 excimer laser system and a Thermo Scientific NeptunePlus MC-ICPMS for all necessary non-traditional stable isotope analyses.

The potential candidate should hold a PhD degree in Geosciences and provide an excellent understanding of mantle petrology and isotope geochemistry. Substantial experience in clean laboratory work and handling of mass spectrometers, such as MC-ICP-MS and/or TIMS are expected. Fluency in both written and spoken English is a prerequisite. Experience with writing and publishing scientific results in internationally recognized peer-reviewed journals is requested.

The position is initially for 2 years with options for extension. Salary and benefits are commensurate with the German employee scale TV-L E13 (100%). As the University of Tuebingen intends to increase the proportion of female employees in science, women are particularly encouraged to apply. In case of equal qualification and experience physically challenged applicants are given preference.

Please send your application as a single PDF file, subject: O2RIGIN, with detailed curriculum vitae, list of publications, certificates, a one page statement of research interests together with names and contacts of 2 potential references to the E-Mail address given below. Application reviewing starts on October 1st and continues until the position is filled.
