About me
I am currently an ANSSI-Inria postdoc in Mathematics and Cryptography, in the GRACE team at Inria Saclay. I obtained my PhD from Sorbonne Université in 2022 under the supervision of David Madore and Fabrice Orgogozo. From 2022 to 2024, I was a postdoc in the C² team at Télécom Paris.
Research
My research focuses on the interplay between cryptography, arithmetic geometry, and coding theory.
