PhD and Postdoc Positions in Planetary Science, Planetary Geodesy, and Asteroid Evolution at the University of Bern University of Bern in Switzerland

Two PhD positions and one postdoctoral position are available at the University of Bern in the area of planetary science, planetary geodesy, asteroid evolution, and small-body research. The opportunities are tied to ESA’s upcoming RAMSES mission and the Swiss National Science Foundation project on characterising near-Earth asteroid Apophis using mission data.

PhD 1: Numerical Modeling of Asteroid Evolution — This project focuses on collisional evolution, crater formation, regolith processes, tidal deformation, and surface reshaping of Apophis. Applicants should have a master’s degree in (astro-)physics, astronomy, planetary science, or a related field, plus strong numerical modeling and programming skills. Experience with SPH/N-body simulations, granular physics, or geophysical modeling is an advantage.

PhD 2: Space Geodesy for Asteroids — This project centers on gravity field determination, rotation state, interior structure, and geodetic parameter estimation for Apophis using radiometric tracking, laser ranging, and optical camera data. A completed master’s thesis in astronomy, geodesy, physics, or a related topic is expected; experience with orbit and gravity field determination is beneficial.

Postdoc: Space Research and Planetary Sciences / Astronomical Institute — The postdoctoral project develops a numerical Apophis Reference Model integrating shape, rotation, surface properties, and interior mass distribution. A PhD in (astro-)physics, astronomy, planetary science, geology, or a related field is required, along with scientific programming skills and a strong interest in planetary sciences and small-body research.

All positions are fully funded at the University of Bern and offer a collaborative international research environment, access to computational resources, and participation in a high-impact ESA mission. The PhD positions are full-time fixed-term roles with salary following University of Bern guidelines; the postdoc is funded for 2 years with a possible 1-year extension. The application deadline for all three positions is 2026-06-30.

Applications should include a motivation letter, CV, degree documents/transcripts, and two referees’ names and email addresses. Submit the application by email to the contact person listed for the specific position.
