Since October 2024, I'm a postdoctoral researcher in Quantum Information team of Sorbonne University working with Alex Grilo.
Before that, I received my PhD in computer science from École Normale Supérieure de Lyon under the supervision of Damien Stehlé and Gilles Villard .
I received my Master's degree in theoretical computer science from the same university.
I’m broadly interested in many areas of computer science. My research focuses on quantum algorithms and cryptography.
One of my major interests is designing quantum algorithms for Euclidean lattices, analyzing their algorithmic aspects and their computational hardness (both classical and quantum), and studying the advantage that they bring to cryptography.
I also work on post-quantum cryptography which consists of understanding the security, efficiency, and implementation aspects of cryptographic tools (signatures, zero-knowledge proofs, multiparty computations, ...) in the presence of quantum computers.
I am also interested in developing algorithms and hardware-aware cryptography to be run on near-term quantum computers.
