PhD Position in Extragalactic Astrophysics at the University of Geneva

Closing date: 2026-09-06
Contact: Romain Meyer

About the role

We invite applications for a 4-year PhD position focused on the Epoch of Reionisation at the Department of Astronomy at the University of Geneva. The successful applicant will work on novel observational studies of the intergalactic medium at z>5 and the nature of the sources of reionisation in a new group led by Romain Meyer.

The team will initially be composed of one postdoctoral researcher and two PhD students. The PhD position will leverage new JWST spectroscopy of galaxies in deep extragalactic fields and/or VLT observations from MUSE and the new-generation MOONS instruments. The candidate will be part of international JWST collaborations (COSMOS-3D, FRESCO, EREBUS, JWST-OutThere) and the MOONS Consortium.

The position is fully funded for 4 years. Computer equipment, travel funding, and access to local HPC infrastructure are included.

Research environment

The Department of Astronomy at UNIGE in Switzerland carries out research in the fields of extra-solar planets, stellar physics, high-energy astrophysics, galaxy evolution and dynamics, and observational cosmology, providing a rich and vibrant research environment. Geneva is one of the most international and multicultural cities in Europe with a high quality of living, with the stunning Swiss/French Alps and Lake Geneva in close proximity.

Requirements

• Master degree in Astrophysics or a related field (by the start of the PhD position)
• Some experience in research and Python
• A background in extragalactic studies (especially JWST or VLT spectroscopy) is an asset

The successful applicant will become part of a dynamic environment; we especially look for team players with a high level of reliability and motivation to learn quickly.

Start date & Pay

Start date: January 2027 (negotiable).

We offer a competitive salary in agreement with the State of Geneva public sector and UNIGE standards.
