About this position
CNRS is advertising a researcher position at the Laboratoire des Ecoulements Géophysiques et Industriels (LEGI) in Gières, Isère, France, within the MOST team (Modelling and Simulation of Turbulence). The project focuses on goal-oriented multi-fidelity strategies for the prediction of turbulent flows, combining RANS, hybrid RANS/LES, and LES simulations to choose the best simulation strategy for a given prediction objective.
The research aims to optimize the trade-off between accuracy and computational cost, with strong emphasis on uncertainty quantification, criteria for evaluating the contribution of each simulation, and extension from integrated quantities to the reconstruction of complete statistical fields. The work will be implemented and validated in the YALES2 code and will use high-performance computing resources.
This is a fixed-term research contract of 18 months with a gross monthly salary between 3041.58€ and 4216.70€ depending on experience. The position is suitable for candidates with a PhD in Fluid Mechanics, Physics, Applied Mathematics, Scientific Computing, or a related field. Strong CFD skills are expected, and experience with data science, machine learning, statistical methods, or HPC is an asset.
Application materials include a CV, publication list, reference contacts, and a short research statement (1–2 pages). The deadline is 2 October 2026. Scientific contact: Thomas Berthelon (MOST team, University Grenoble-Alpes).
