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.
