PhD Position in Noble Gas Isotope-Cosmochemistry

100%, Zurich, fixed-term

The Noble Gas Cosmochemistry Group (Prof. Henner Busemann) studies the most volatile elements in all types of extraterrestrial materials. It is part of the Institute of Geochemistry and Petrology of ETH Zurich’s Department of Earth Science.

We seek a highly motivated, flexible, and team-oriented doctoral candidate with a strong interest in the laboratory-based analysis of extraterrestrial samples. The position is expected to start in June 2024 (negotiable) and is fully funded for a maximum of 4 years.

Project background

Pristine meteorites and samples returned from asteroids are the best material available to study the formation of the early solar system and subsequent processes in the nebula and on small planetary bodies. A main goal of this project is to search for evidence in the noble gas record for the early solar system dichotomy that has been suggested based on various other isotope observations in meteorites. Furthermore, we aim to better characterize potential carrier materials of elusive but now well-established noble gas components and to improve our understanding of the chronology of the events that formed the solar system.

Job description

The project, mainly funded by the Swiss NSF, will utilize noble gas mass spectrometry. It may also include various methods to resolve and identify carriers of the various noble gas components spatially, physically, and chemically, using an in-vacuum etching device unique to ETH Zurich. The development of new instrumental methods as well as the efficient usage of world-class equipment will be an important part of the laboratory tasks. Research results should be presented regularly at international conferences and published in high-profile journals.

Your profile

• MSc or a comparable degree in Earth or Environmental Sciences, Chemistry, Physics, or related fields
• A background in a field such as mass spectrometry, analytical instrumentation, isotope geochemistry, or planetary sciences is desirable
• Motivation, creativity, flexibility, patience, independence, strong experimental or instrumental interests, and ability to work closely together in a small team
• Good English writing and communication skills
