Valentin Resseguier

Position & Research areas

I am a permanent researcher ("chargé de recherche") in ACTA team of UR Opaale (INRAE).

I work on new kinds of stochastic closures for fluid dynamics applications. It assumes that the transporting velocity is partially random (e.g. Gaussian processes) due to time coarse-graining. It has lead to randomized reduced order models and Large Eddy Simulations (LES) models. I explore several applications such as data assimilation, uncertainty quantification, and wave-turbulence interactions. I have also studied mixing analysis from both deterministic and stochastic points of view.

I am applying these methodologies to wind turbines, sailing, airborne systems, wave and ocean modeling, and pollutant leak detection, using e.g. data assimilation.
