I am currently a post-doctoral research at Inria and ENS de Lyon, France.
I work with Damien Stehlé on RISQ project (Regroupement de l'Industrie française pour la Sécurité post-Quantique).

Before that, I was a Ph.D. student in Cryptographic Implementations group, Technische Universiteit Eindhoven, The Netherlands.
Before that, I was a master student in Imai's Laboratory, The University of Tokyo, Japan.

My resume is available in English and French.
