Postdoctoral Position 2026 theoretical cosmology

The LAPTh (CNRS/USMB) invites expressions of interest for a postdoctoral researcher position in theoretical cosmology. The position is dedicated to developing a robust and efficient framework that incorporates a broad range of neutrino and dark-matter models, assessing their effects on large-scale-structure (LSS) statistics as measured by the power spectrum and bispectrum of galaxies or intensity maps. The project emphasizes spectroscopic galaxy surveys—in particular the analysis of data from the ESA Euclid mission—and 21-cm intensity mapping, especially from the SKA Observatory (SKAO). Our goal is to generalize existing analytic methods—particularly the Effective Field Theory of Large-Scale Structure (EFTofLSS)—to include the effects of massive neutrinos and non-standard dark matter, validate theoretical predictions against simulated datasets, forecast expected constraints from Euclid and SKAO, and ultimately analyze the Euclid spectroscopic galaxy sample in its second data release.

We invite applications for two postdoctoral positions in string cosmology (broadly defined) in France: one at IP2I (CNRS, UCBL), Lyon, with Dimitrios Tsimpis, and one at LAPTh (CNRS, USMB), Annecy, with David Andriot.

The positions are funded thanks to the ANR Grant DarES.

In memoriam Richard Taillet

Notre laboratoire est endeuillé à la suite du décès de notre collègue Richard Taillet, survenu le 6 août 2025 des suites d'une maladie foudroyante.

Richard a effectué ses études en tant qu'élève fonctionnaire de l'Ecole Normale Supérieure de Lyon.
