Julien Reygner

Julien Reygner is a Professor at École des Ponts ParisTech (ENPC) and Deputy Director of CERMICS research laboratory. He holds a concurrent part-time position as Associate Professor at École Polytechnique. His academic background includes a PhD from Sorbonne Université (2011-2014) and a Habilitation thesis (2021). He has held positions as Assistant Professor at ENPC (2018-2023) and CNRS postdoctoral fellow at ENS Lyon (2014-2015).

Reygner's research explores stochastic processes, particle systems, and numerical methods with applications in uncertainty quantification. His work bridges probability theory with mathematical analysis and statistical mechanics. Primary domains include Langevin dynamics, mean-field systems, Fokker-Planck equations, and computational statistics.

His publications demonstrate consistent focus on stochastic modeling, particle methods, and probabilistic approaches to partial differential equations. Recent work emphasizes convergence analysis, structural reliability, and applications in statistical learning.

He actively advises doctoral candidates, including projects on particle systems, Langevin processes, and structural fatigue. Research grants include ANR projects: Conviviality (2023-2028), QuAMProcs (2019-2024), and EFI (2018-2022). He leads CERMICS' Applied Probability team and co-organizes seminars on data transitions and uncertainty quantification.
