Postdoctoral Position in Theoretical Cosmology Probing Dark Matter and Cosmic Neutrinos with Large-Scale Structure

About this position

• The Laboratoire d’Annecy de Physique Théorique (LAPTh) invites
• applications for a postdoctoral position in theoretical cosmology
• within DarkES, a joint ANR–DFG research project co-led by Dr. Azadeh
• Moradinezhad (LAPTh) and Prof. Julien Lesgourgues (RWTH Aachen
• University).

• The project aims to develop a robust and efficient framework for
• probing the nature of dark matter and neutrinos with
• large-scale-structure (LSS) observations. The focus will be on
• incorporating a broad range of neutrino and dark-matter models into
• predictions for the power spectrum and bispectrum of galaxies and
• intensity maps, with particular emphasis on spectroscopic galaxy
• surveys, including the ESA Euclid mission, and 21-cm intensity mapping
• with the SKA Observatory (SKAO).

• The project will generalize analytical methods, in particular the
• Effective Field Theory of Large-Scale Structure (EFTofLSS), to include
• massive neutrinos and non-standard dark matter. The work will combine
• theoretical modeling with N-body simulations and forecasts for Euclid
• and SKAO, with the longer-term goal of applying the framework to the
• Euclid spectroscopic galaxy sample.

• Qualifications. A PhD focused on cosmology completed by the start
• date; familiarity with perturbative modeling of biased tracers of LSS;
• a strong command of analysis of N-body simulation to validate analytic
• predictions of clustering statsitics; and ideally experience with
• galaxy survey data analysis. Strong programming skills in Python and C
• are expected.

• Supervision and environment. The position will be supervised by Dr.
• Azadeh Moradinezhad within the Astroparticle and Cosmology group at
• LAPTh (astrocosmolapth.com). The successful candidate will work
• closely with the group of Prof. Julien Lesgourgues at RWTH Aachen and
• the group of Prof. Mathias Garny at the Technical University of
• Munich, and will have the opportunity to join the Euclid Consortium.
• Two PhD students will also be involved in the DarkES project, offering
• opportunities for co-supervision. The position provides access to
• CNRS/LAPTh computing resources and travel support, as well as
• interactions with the broader regional community (e.g. University of
• Geneva and CERN).

• Terms. The appointment is for two years. Salary on the CNRS scale,
• commensurate with experience, including social security and health
• coverage. The expected start date is 1 October 2027, with some
• flexibility.

Applications. Submit via AcademicJobsOnline:

• a cover letter,

• a CV with a list of publications,

• a research statement (up to four pages),

• three letters of recommendation, arranged by the applicant.

• Applications received before November 20th, 2026 will receive full
• consideration; the position remains open until filled. Shortlisted
• candidates will be invited to a remote interview.
