PhD student position in space research and astrobiology

The Space Research and Planetary Sciences Division of the University of Bern is seeking candidates for a PhD in physics to work on Rosetta legacy mass spectrometer data obtained at comet 67P/Churyumov‑Gerasimenko (67P). The position, funded by the Swiss National Science Foundation (SNSF), is nominally for 3 years with a possible 1 year extension. The intended start date falls within the May‑July 2026 timeframe.

The Bern‑led high‑resolution Double Focusing Mass Spectrometer (DFMS) aboard ESA's Rosetta mission revealed an unexpected chemical diversity and complexity in cometary matter. The research project uses DFMS legacy data as a unique testbed to investigate cometary abiotic organic complexity and establish references for ongoing and future space missions—particularly those employing mass spectrometers in the search for signs of life.

• Apply chemical analytics, including neutral gas mass spectrometry, in the context of astrobiology.
• Systematically evaluate selected high‑resolution mass spectra using search methods targeting chemical groups of astrobiological interest (e.g., sugars, lipids, prebiotic molecules).
• Where necessary, perform reference measurements with laboratory flight spare instruments.
• Collaborate within a multidisciplinary team and present research at international conferences and workshops.

• Master of Science degree in astrochemistry, astrobiology, or a related field.
• Experience with mass spectrometry.
• Programming skills in Python.

The salary will be determined according to SNSF regulations. Rules according to the University of Bern and Canton of Bern apply. Childcare allowance is available. The Canton of Bern offers 25 days of vacation per year. Public holidays (e.g., Christmas, New Year, Easter, 1 August, etc.) are in addition.

• Full‑time
• Internship level: not applicable (PhD)

Interested applicants should submit a curriculum vitae (including details of professional experience and skills), a one‑page motivation letter, contact information for two referees, and a transcript of Master‑level grades to Dr. Nora Hänni: nora.haenni.

The University of Bern is an equal‑opportunity employer committed to diversity in its workplace, and applications from under‑represented groups are encouraged.
