16/10/2026, Arrival of Agustín Somacal (Hi!Paris researcher)

Agustín Somacal joined our lab starting on October 12th as assistant professor AI fellow for 3 years, on a funding provided by Hi!Paris. He has a background in physics (University of Buenos Aires) and applied mathematics (Ph.D., Sorbonne Université, supervised by Profs. Albert Cohen and Olga Mula). From 2024 he was postdoctoral researcher in Ecole Centrale de Nantes. Agustín’s research centers on non-linear model order reduction and physics-informed learning to tackle forward and inverse problems by integrating advanced optimization strategies for practical, real-world applications.

6/10/2026, Scientific day for the creation of UMR 9032

On Friday, November 6th, we organize a scientific day to celebrate the creation of CERMICS as a joint research unit with CNRS. See the program of the event.

1/10/2026, Arrival of Laura Grazioli (CNRS researcher)

Laura GRAZIOLI joined our lab as a CNRS researcher from 1st October. She was trained as a theoretical chemist, obtaining her PhD at Johannes Gutenberg-Universität, Mainz, under the supervision of Prof. Ju4rgen Gauss and Prof. Stella Stopkowicz. She later decided to deepen her knowledge of the mathematical aspects of quantum chemistry, joining us as a postdoc from 2024. Her research interests are mainly in the domain of wave function theory for the description of electronic states, placing her research at the interface between theoretical chemistry and applied mathematics.

17/07/2026, Julien Guyon writes in the French newspaper L'Equipe

Julien Guyon wrote in the French newspaper L’Equipe a brief, accessible overview of the fundamental concepts of bias, variance, and randomness, using the 2026 World Cup football draw as an example: Which team was the luckiest/unluckiest during the draw? And also in English in the quantitative finance magazine Risk. This is joint work with Thomas Buchholtzer, a student in the IMI department at École des Ponts, who is set to begin a PhD this fall.

6/06/2026, Andrew McRae receives the 2026 SIAM Activity Group on Optimization Best Paper Prize

Andrew McRae, together with Nicolas Boumal (EPFL, Switzerland), received the 2026 SIAM Activity Group on Optimization Best Paper Prize. This prize is awarded every three years to the author(s) of the most outstanding paper, as determined by the prize committee, on a topic in optimization published in the four calendar years preceding the award year.

Andrew and Nicolas received the prize for their paper “Benign Landscapes of Low-Dimensional Relaxations for Orthogonal Synchronization on General Graphs”. This work provides rigorous theoretical guarantees on the nonconvex landscape of a low-dimensional relaxation for orthogonal group synchronization problems, which appear in many practical applications such as robotics, imaging, and computer vision.

Le CERMICS est le centre de recherche en mathématiques appliquées de l’École nationale des ponts et chaussées. C’est une unité mixte de recherche avec le CNRS (UMR 9032). Il héberge des équipes-projets communes avec Inria Paris et l’Université Gustave Eiffel, et fait partie de la Fédération CNRS Bézout ainsi que de l’école doctorale EDMH. L’acronyme CERMICS signifie « Centre d’Enseignement et de Recherche en MathématIques et Calcul Scientifique ».

Les chercheurs travaillent dans trois grands domaines : Probabilités appliquées ; Modélisation, analyse et simulation ; Optimisation. L’originalité du centre réside dans sa capacité à construire des ponts entre approches déterministes et stochastiques et à produire à la fois des résultats théoriques et des méthodes numériques, avec de fortes interactions avec des partenaires industriels issus de domaines variés (transport, énergie, finance, ingénierie, industrie pharmaceutique) et avec des scientifiques académiques d’autres disciplines (biologie, chimie, physique et science des matériaux).


Voici quelques vidéos donnant un aperçu des recherches menées au CERMICS. Voir la playlist complète. Voir également la playlist des étudiants du CERMICS présentant leurs travaux, ainsi que les contributions des membres du CERMICS à Ingenius, le magazine numérique de l’École des Ponts.
