Mathematics

Knowledge is a real strength

Since Sepember 2019, I’m a lecturer at the CY Cergy Paris Universite (formerly known as University of Cergy-Pontoise & EISTI school). I came back to France to join the team of the special program International Bachelor Ygrec in Data Science.

A (very extended) CV is available here (v2021/11)!
