Postdoctoral Research position in Observational Cosmology at IFAE

Open Position Postdoctoral Research position in Observational Cosmology at IFAE. Opening Date September 23, 2026 Closing Date Until Filled Reference IFAE2026/39_COSMOLOGY_Postdoc About IFAE The Institut de Física d’Altes Energies (IFAE) is a public consortium of the Generalitat de Catalunya, the Autonomous Government of Catalonia, and the Universitat Autònoma de Barcelona (UAB, a public university) whose main objective is to carry out research and to contribute to the development of high energy physics from a theoretical, experimental and technological point of view. IFAE has the status of a “University Institute" attached to the UAB and its premises are within the campus of the University. About The Observational Cosmology Group The IFAE Cosmology group is presently formed by 5 faculty, 7 post-docs and 10 students and is a full member of the Euclid Consortium and the Dark Energy Science Collaboration (DESC) of the Legacy Survey of Space and Time (LSST) at the Vera Rubin Observatory, as well as the Dark Energy Survey (DES), and the Dark Energy Spectroscopic Instrument (DESI). The group plays leading roles in the analysis of all the surveys it participates. The ERC-funded COSMO-LYA research group, led by Andreu Font-Ribera, is using innovative techniques and new data from the Dark Energy Spectroscopic Instrument (DESI) to address some of the open questions in fundamental physics. Job profile and tasks The successful candidate will join the COSMO-LYA project and the Observational Cosmology group at IFAE, and will become a member of the DESI collaboration. The main goal will be to develop and validate new methodologies to go beyond the state-of-the-art in data analysis of galaxy and quasar surveys, and apply them to the third data release of DESI (DR3), expected in late 2026. The candidate is expected to do international travel and stays for research purposes in addition to collaboration meet-ings and conferences. The successful candidate will be expected to have a PhD in Physics or a related discipline, experience in data analysis of cosmological surveys and in scientific programming, including experience working with High Performance Computing facilities.
