Ukrainian Math Day in Evry Paris-Saclay
“Ukrainian Math Day in Évry Paris-Saclay #1” is a special event where Ukrainian mathematicians share their ongoing research in mathematics with a diverse audience.
Hosted at the University of Évry Paris-Saclay, this event brings together mathematicians, researchers, and students — from undergraduate to PhD level — to explore topics in pure and applied mathematics.
Through insightful lectures, engaging discussions, and valuable networking opportunities, the event seeks to promote knowledge exchange and support the Ukrainian mathematical community, which has been dispersed across Europe and beyond due to the ongoing war.
Impact IA for master student
Cet événement est conçu pour échanger “au delà des mathématiques” sur les conséquences écologiques, économiques, éthiques ou juridiques de l’utilisation des modèles d’IA.
Co-financée par la FMJH et DATAIA, la journée ImpAct s’adresse en priorité aux étudiants de master de Paris-Saclay, plus particulièrement aux étudiants en mathématiques (Data Science, IA…). Un public plus large est bienvenu dans la limite des places disponibles.
Change-Point Paris-Saclay conference (January 2023)
Co-organizer with Charles Truong
The Paris-Saclay Change-Point workshop is a 2-day meeting (January 16th and 17th 2023) dedicated to theoretical and applied methods for solving change-point detection problems. The primary goal of the workshop consists in fostering new interactions within the European community of change-point researchers. This event is free of charge (no registration fee) and open to anyone willing to contribute to the development of the field (M2 students, PhD, young and senior researchers).

5. Current job
Assistant Professor in statistics since September 2019 at the University of Evry (near Paris) in the laboratory LaMME. My current research is about changepoint detection using pruned dynamic programming algorithm with a focus on the multivariate framework and application to genomics.
As an Applied Mathematician, I like to work at the interface of different fields. My current and past interests are
Statistics : Change-point detection (by dynamic programming)
Optimization : Convex optimization, Computational geometry, Quadratic and linear programming.
Numercial analysis : Quasi-Newton algorithm
Package development : gfpop, dust (see github)
In particular, problems involving optimization tools are among my favorites..
