Two PhD and a Post-Doctoral Position in Petrology

The petrology group at the University of Bern invites applications for two PhD positions (four years) and one position for a post-doctoral researcher (three years) to participate in a project funded by the Swiss National Science foundation on subduction of water through the evolution of the Earth led by Prof. Jörg Hermann. The project combines fieldwork with petrology, geochemistry and thermodynamic modelling, with a strong focus on in-situ measurements of H2O by infra-red spectroscopy and trace elements by LA-ICP-MS.

The project is integrated in a large research group interested in quantifying and modelling geochemical exchanges in metamorphic systems and will be carried out in close collaboration with Prof. Daniela Rubatto, Prof. Thomas Pettke, Prof. Pierre Lanari (Uni Bern), Dr. P. Sossi (ETH Zürich) and international collaborators.

PhD project 1 will focus on H2O incorporation into clinopyroxene and H2O budgets in subducted crust. PhD project 2 deals with H2O in rutile and the onset of cold subduction. The applicants should hold a Master degree (or equivalent) in Earth Sciences and have a vivid interest in geochemistry and petrology. Some experience with analytical techniques, especially with in-situ major and trace element analysis and/or spectroscopic methods is welcome.

The post-doctoral researcher will focus on H2O recycling in the Archean and how this impacts on TTG formation. This sub-project will also contain an experimental component. We are looking for a highly motivated researcher with a doctoral degree and a broad interest in petrology. The successful candidate is expected to conduct research, participate in collaborative projects and assist with supervision of MSc and PhD students.

The application should include a CV, a statement of research interests, a full list of publications and the contact information of three potential referees. The University of Bern is committed to increasing the number of women in research and teaching and therefore applications from female candidates are encouraged.

The positions will be available from February 2021.

Please send your application by December 1st, electronically as a single PDF to Prof. Jörg Hermann, e-mail:
