01 / About
Mathematical ideas,
made computational.
My work sits at the intersection of numerical analysis, partial differential equations, and optimization. I am especially interested in methods that are theoretically sound, computationally efficient, and useful for real physical systems.
I currently study shape optimization for Stokes flow at the Laboratoire des Sciences du Numérique de Nantes (LS2N, CNRS), using finite element methods to minimize hydrodynamic resistance. Previously, I worked on robust signal estimation, low-rank modeling, and parameter identification.
