The Institute of Geology, Mineralogy and Geophysics at the Faculty of Geosciences is looking for a 

research associate (m,f,x) for 3 years, 29,8725 hours per week, TVL E13

The German Science Foundation (DFG) is funding the second round of the Research Unit “Diffusion Chronometry of Magmatic Systems” (FOR 2881) to be hosted at the Ruhr-Universitaet Bochum and the Leibniz Universitaet Hannover for 3 more years. The objective is to carry out experimental measurements and develop theoretical modelling tools for diffusion chronometry in various high temperature systems – the focus will be on igneous systems, but most tools will be very much applicable to metamorphic systems and meteorites as well. More information on the project may be found at:

Within the scope of this Research Unit, we are seeking candidates to fill 3 PhD student positions in Bochum. One of the positions is described below.

extent: part-time
duration: temporary
beginning: as soon as possible
application deadline:

Your tasks:

  • We are looking for a PhD candidate to determine the residence times at different levels of a plumbing system using a range of diffusion chronometry tools on samples from the Eifel volcanic field, W. Germany. This work will be complemented by studies on chemical differentiation modes in magma mush zones. The objective will be to use the results in conjunction with modeling and phase equilibria results from other projects in the research unit and various other sources of geological and geophysical information (structure, seismicity, volatile flux) to better constrain processes leading to maar formation and explosive mafic volcanism. The project includes field work and sampling in the Eifel Volcanic Field, Germany. Main tasks of the PhD candidate will be field sampling of volcanic sequences, petrographical and chemical analysis and data processing, thermodynamic modeling, and kinetic modeling using novel tools that are being developed as part of this Research Unit. Studying the differentiation processes frozen in a magma mush zone will be a one-of a-kind experience.

Your profile:
The following skills are required:

  • Strong interest in interdisciplinary work and scientific exchange within the Research Unit
  • Ability to work independently as well as part of a team with international collaborations
  • Excellent time management and communication skills
  • Very good computer and written and oral skills in English
  • Strong background (MSc or equivalent) in Earth science or related disciplines, ideally with a deeper background in petrology and mineralogy
  • A strong interest in quantitative modelling

The following skills are desirable:

  • Experience in the study of volcanic rocks
  • Experience with analytical equipment (EMPA, XRF, ICP-MS etc.)
  • Coding experience with Matlab, Fortran, C++, etc.

Our offerings:

  • a qualified induction programme
  • Team-orientated cooperation in a committed, international and appreciative team
  • Support in reconciling family and career/academia (including childcare arrangements, holiday offers, mobile nursery)

Additional information:

At the request of the applicant (m,f,x), the staff council may be involved in selection interviews.

If the position is funded by third-party funds the employee has no teaching obligation.

German language courses are offered by the University Language Center (ZfA) in the field of German as a Foreign Language (DaF).

The Ruhr-Universität Bochum is one of Germany’s leading research universities, addressing the whole range of academic disciplines. A highly dynamic setting enables researchers and students to work across the traditional boundaries of academic subjects and faculties. To create knowledge networks within and beyond the university is RUB’s declared aim.

The Ruhr-Universität Bochum stands for diversity and equal opportunities. For this reason, we favour a working environment composed of heterogeneous teams, and seek to promote the careers of individuals who are underrepresented in our respective professional areas. The Ruhr-Universität Bochum expressly requests job applications from women. In areas in which they are underrepresented they will be given preference in the case of equivalent qualifications with male candidates. Applications from individuals with disabilities are most welcome.
