Présentation
I was born the 14th of May 1972. I defended my Ph.D. in 1999 on computational topology, combinatorics and embedding, directed by Jean-Laurent Mallet. I was awarded the SPECIF prize (now known as Gilles Kahn / Acad. Sci. prize) of the best French Ph.D. thesis in CS, then I did a post-doc in Stanford in 2000. I was hired by Inria in 2000 as a junior researcher. In 2004, I created the ALICE team (it became an Inria project in 2006) [Archives ALICE 2006-2018]. I obtained an ERC Starting Grant (GOODSHAPE) in 2008, and an ERC Proof of Concept Grant (VORPALINE) in 2013. I was promoted research director in 2008. I was awarded the Inria Young Researcher Award in 2011, was promoted 1st class research director (DR1) in 2012 and exceptional class (DR-CE) in 2021. In 2019, two new Inria teams stemmed from my previous team ALICE: MFX on compter aided fabrication, and PIXEL on geometry processing. From Nov. 2018 to Dec. 2022, I was the director of the Inria Nancy Grand-Est research center (450 people, 20 teams, 17 in Nancy, 3 in Strasbourg). I was promoted to the 2nd level of the exceptional class (DR-CE2) in 2025. I am now the scientific director of Program Inria Quadrant, the french high-risk high-reward research program on digital sciences and technologies, that I contributed to create.
My initial topic is Geometry Processing. From 1998 to 2006, I focused on the problem of mesh parameterization, and invented several algorithms (one of them, LSCM, was selected in Seminal Graphics Papers: pushing the boundaries, the book published for the 50 years of the ACM SIGGRAPH conference). Then I contributed to two start-up creations, for transferring my results in 3d gridding (Paradigm/Earth Decision Sciences) and visualization (Scalable Graphics)
From 2006 to 2019, I focused on some numerical problems in Scientific Computing. I contributed to lay spectral geometry processing fundamentals and made it practical with the first algorithm that computes a Fourier-like basis for surface meshes (manifold harmonics). I also established the regularity of Lloyd's energy and proposed a Newton solver for quantization, generalized it to propose the first automatic algorithm for hex-dominant meshing (Lp-CVT) and finally the first solver for 3D semi-discrete optimal transport. Most of my research results are available in my GEOGRAM and GRAPHITE Open-Source softwares. The main results of my two ERC projects on meshing and sampling are transferred to Tessael, a start-up we have created.
Now (2020,...) I am mainly working on computational methods for cosmology (Physical Review Letters, 2022 and 2023) and fluid dynamics (Journal of Computational Physics, 2022). I'm also interested in novel hardware architectures.
