Doctoral Position in Isotope Cosmochemistry
100%, Zurich, fixed-term
The Planetary Geochemistry group (Prof. Maria Schönbächler) investigates the pathways that led to the formation and evolution of planets in our solar system. The group is part of the Institute of Geochemistry and Petrology at the Department of Earth and Planetary Sciences, ETH Zurich.
We are seeking a highly motivated, curious, and team-oriented doctoral candidate with a strong interest in the laboratory-based analysis of terrestrial and extraterrestrial samples. The position is available from spring 2026 (negotiable) and is fully funded for a maximum of 4 years.
Project background
Meteorites are precious material mainly originating from asteroidal bodies, which formed during the time when planets started to accrete. As such these bodies are leftover planetary building blocks. This project will use meteorite samples to establish genetic relationships among asteroidal bodies and planets, and to gain new insights into physico-chemical processes in the early Solar System that shaped the composition of planetary bodies.
Job description
The PhD project will include geochemical and mass spectrometric investigations to determine nucleosynthetic isotope variations in extraterrestrial samples with the goal to improve our understanding of the processes involved in the formation and evolution of planets. Your tasks will centre around:
- Sample characterisation of meteorites (e.g., EMS, SEM)
- Sample preparation and improvements of analytical methods, a substantial amount of work will take place in our state-of-the-art clean-room laboratories
- high-precision isotope analyses by MC-ICP-MS
- modelling and interpreting your research results in the context of the broader literature
- presenting the results at international conferences and publishing in high-profile journals
Profile
- Masters or comparable degree, preferably in a subject related to the PhD project, such as in Earth or Environmental Sciences, Chemistry, Physics or Planetary Sciences
- Highly self-motivated, curious, independent, affinity for laboratory work, strong experimental or instrumental interests, commitment to accurate and precise lab analyses, and ability to work closely in a team
- Research experience in analytical geo- or cosmochemistry are advantageous
- Good English writing and communication skills
