Personal webpage of Quentin Chauleur


I am currently a CEMPI postdoc at the Laboratoire Paul Painlevé, Université Lille, under the supervision of Guillaume Dujardin (Paradyse, INRIA Lille).

Between 2019 and 2022, I was a PhD student at IRMAR, Université de Rennes 1, under the supervision of Rémi Carles and Erwan Faou.

My codes are available on my gitlab. Here is my Curriculum Vitae (in french, last updated 02/24).

Research interests

• Analysis of nonlinear PDEs (Schrödinger, Navier-Stokes, Euler): Cauchy problem, long time dynamics, stability of particular solutions.
• Numerical analysis: time/space discretization, convergence analysis.
• Simulation of nonlinear phenomena: vortex nucleation, solitary waves.

PhD thesis

The 5th of July 2022, I defended my doctoral thesis entitled "Around Schrödinger-Langevin equation and isothermal Euler system with damping".
