About

I completed my PhD in March 2025 at IRIF, Université Paris Cité, under the supervision of Geoffroy Couteau, after starting in October 2021. Before that, I got my Master’s degree (2019 – 2021) in Cryptology and Information Security Cryptis program at Université de Limoges.
My research interests are in various aspects of both practical and theoretical cryptography, including secure multiparty computation, zero-knowledge proofs, and post-quantum cryptography. You can find my PhD thesis here and my CV here.

Research Experience

I spent the summer of 2023 as a research intern at COSIC hosted by Nigel Smart, and the summer of 2024 interning at NTT Social Informatics Laboratories, working with Masayuki Abe.
Before starting my PhD, I interned at XLIM in the summer of 2020 under the supervision of Duong Hieu Phan, and in the summer of 2021, I worked as an intern at IRIF with Geoffroy Couteau.

Presentations

A list of talks where I had the opportunity to present and discuss my work. I have been working on function secret sharing (FSS), pseudorandom correlation generators (PCGs), pseudorandom correlation functions (PCFs), post-quantum signatures (using the MPC/VOLE-in-the-Head paradigm), generic multi-party computation (MPC), and private set intersection (PSI), a specific type of MPC.
