Hello, welcome to
# My home page

Here you will find some
information on my scientific activities as
professor of Applied Mathematics in Jean Kuntzmann Lab
of Grenoble Institute of Technology of Grenoble Alpes University.

Applied mathematician, my research affiliation is the Partial Differential Equations team of the Jean Kuntzmann Lab, and I mainly teach in Ensimag, Grenoble Institute of Technology. My fields of research are mathematical and numerical analysis of PDE.

Research
## What I Do?

I got interested in developing new methods to capture interfaces while recording mechanical properties. Applications are in fluid structure coupling with a particular emphasis on modeling of red blood cells. I co-authored a book on that subject.

I worked on efficient algorithms for dynamic optimal transport and studied some of their analytical properties with Romain Hug and Nicolas Papadakis.

Mainly around doubly nonlinear elliptic-parabolic equations and transport equations.
