He completed his PhD in 2002 at LadHyX on swirling flow instabilities and vortex breakdown. After six years at the Mathematics department of Université de Nice, he joined EPFL in 2009, founding the Fluid Mechanics and Instabilities Lab (LFMI). He became an associate professor in 2016 and served as teaching department director from 2018 to 2023. In 2019, he was named a fellow of the American Physical Society. His research focuses on instability theory, free interface phenomena and microfluidics, with a focus on their fundamental description.

Finite element method ME-372 In this course, the student gets acquainted with the theoretical aspects of the finite element method, the most commonly used computational technique for solving elliptic problems. He learns to apply the finite element method to simple test cases and to more complex problems faced in practice Hydrodynamics ME-444 Nondimensionalized Navier-Stokes equations result in a great variety of models (Stokes, Lubrication, Euler, Potential) depending on the Reynolds number. The concept of boundary layer enables us then to identify the different components of the hydrodynamic drag. Wave drag is finally introduced. Instability ME-466 This course focuses on the physical mechanisms at the origin of the transition of a flow from laminar to turbulent using the hydrodynamic instability theory.
