1-1-1-1-1-1-1-1-1-1-1-1-1-1 From: Sumit Chakraborty <sumit.chakraborty@xxxxxxxxxxxxxxxxxx> Dear all, As part of a research unit funded by the German Science Foundation (DFG), we are seeking applications for one PhD and three post-doctoral scientist positions at the Universities of Bochum and Hannover in Germany. Formal advertisements, requirements for the positions and procedure for application may be found at the following links: https://stellenwerk-bochum.de/jobboerse/best-nr-310184-phd-position-experimental-petrology-2987-hw-3-years-201023-415465 https://www.uni-hannover.de/en/jobs/3952/ https://www.uni-hannover.de/en/jobs/3954/ https://www.stellenwerk-bochum.de/jobboerse/best-nr-310869-postdoc-mfd-3983-hw-3-years-201023-415468 The description below provides descriptions of the positions in one place in a compact form. Please forward the announcement to appropriate candidates; apologies if you receive multiple announcements. Best wishes, Ralf, Stefan, Francois and Sumit ******************************************* The German Science Foundation (DFG) has funded a new Research unit on â??Diffusion Chronometry of magmatic systemsâ?? (FOR 2881) to be hosted at the Ruhr Universität Bochum and the Leibniz Univerisität Hannover for the next 3 years. The objective is to carry out experimental measurements and develop theoretical modelling tools for diffusion chronometry in various high temperature systems â?? the focus will be on igneous systems, but most tools will be applicable to metamorphic systems and meteorites as well. Within the scope of this project we are seeking candidates to fill 1 PhD student position (Bochum) and 3 post-doctoral positions (1 in Bochum, 2 in Hannover). The detailed requirements for each of the positions and the projects, as well as the names of contacts for each project, are provided in the links associated with this announcement and are summarized below. For all of the positions, the following skills are required: â?¢ Strong interest in interdisciplinary work and scientific exchange within the Research unit â?¢ Ability to work both independently and as part of a team with international collaborations â?¢ Excellent management and communication skills â?¢ Very good computer and written and oral skills in English To apply for any of the positions, please send a CV, names of two referees, a motivation letter, grades and overview of techniques and methods used previously in a single Pdf file by email before November 30th, 2020 to the respective contact person named below. All candidates will work collaboratively with scientists and labs in both, Bochum and Hannover, but the primary affiliation (location of employment) for each position is indicated below separately. Ph.D Candidate #1 (Subproject 1): We are looking for a PhD candidate to measure accurate diffusion coefficients of Fe-Mg and various trace elements in orthopyroxene as a function of different variables, including a quantification of the dependence of diffusion rates on major element composition (Mg#) and redox conditions. A novel combination of experimental and analytical techniques will be used to achieve these goals. Pulsed laser deposition (PLD) of thin films on natural single crystals of orthopyroxene will allow to study diffusion in orthopyroxene on the nano-scale using state-of-the-art analytical techniques like FIB-SEM, TEM, and TOF-SIMS. The achieved data set will be of wide use for petrologists and geochemists for diverse applications including diffusion chronometry, geothermobarometry, and geochronology. The position is a fixed term contract for 36 months (TVL E13, 75%, salary based on the Collective Agreement for the German Public Service). Requirements: â?¢ Strong background (MSc or equivalent) in Earth science or related disciplines, ideally with a deeper background in petrology and mineralogy â?¢ An interest in experimental work and quantitative modelling. Desirable: â?¢ Experience in experimental petrology â?¢ Coding experience with Matlab, C++, etc.. More information: Ralf Dohmen (ralf.dohmen@xxxxxx) or Harald Behrens ( h.behrens@xxxxxxxxxxxxxxxxxxxxxxxxxxx) Employment affiliation: Bochum Post-doc Position #2 (Subproject 3): We are seeking a Post-doctoral scientist to carry out an experimental study to understand isotopic fractionation due to diffusion in high temperature systems. The candidate will be required to analyze zoned olivine crystals from diffusion experiments with the electron microprobe and to conduct in situ Fe-, Mg- and Li isotope analyses with femtosecond Laser ablation MC-ICP-MS. The candidate will contribute to the development of new modelling tools in order to interpret diffusion-driven chemical and isotopic zoning in olivine (and other silicates). A strong background in analytical work with LA-ICP-MS (including trace elements, isotopes) and microprobe and in modelling skills (especially diffusion modelling) is required. Understanding of experimental geochemistry, petrology and volcanology is desired. The position is a fixed term contract for 36 months (TVL E13, 100%, salary based on the Collective Agreement for the German Public Service). More information: Stefan Weyer (s.weyer@xxxxxxxxxxxxxxxxxxxxxxxxxxx) or Ralf Dohmen (ralf.dohmen@xxxxxx) Employment affiliation: Hannover Post-doc Position #3 (Subproject 4): We are seeking a Post-doctoral scientist to carry out phase equilibria experiments (and some textural maturation studies) in calc-alkaline systems at high pressures (P) and temperatures (T) using an internally heated pressure vessel. The candidate will perform the high P-T experiments, analyze experimental run products with EPMA, SEM, FTIR and Raman (potentially, Mössbauer as well). The experiments will be applied to quantify the role of volatiles and oxygen fugacity on the stability and composition of silicate phases and to develop appropriate fractionation models in calc-alkaline magmatic systems. A strong background in high pressure experimental work, petrology and geochemistry of igneous systems, and an understanding of thermodynamic modelling is required. The position is a fixed term contract for 36 months (TVL E13, 100%, salary based on the Collective Agreement for the German Public Service). More information: Francois Holtz (f.holtz@xxxxxxxxxxxxxxxxxxxxxxxxxxx) or Sumit Chakraborty (Sumit.Chakraborty@xxxxxx) Employment affiliation: Hannover Post-doc Position #3 (Subproject 6): We are seeking a Post-doctoral scientist to develop user-friendly programs for diffusion modelling in different kinds of systems. A strong background in numerical methods and code development is required, with experience in Fortran, Python and Matlab. Experience with Java and development of web-based programming will be an advantage, as will be experience with modelling of mass and heat transport, and specifically, diffusion related processes and moving boundary problems. A background in Geochemistry â?? Petrology is desired but not required. The position is a fixed term contract for 36 months (TVL E13, 100%, salary based on the Collective Agreement for the German Public Service).
