I am a postdoctoral researcher at Inria Saclay in the GRACE team. My work focuses on post-quantum cryptography, particularly on lattice-based and code-based problems, in both classical and quantum settings. I am especially interested in transferring techniques between these domains.
Previously, I was a postdoctoral researcher at CWI in Amsterdam.
From 2020 to 2023, I completed my PhD under the supervision of André Chailloux and Nicolas Sendrier in the COSMIQ team at Inria Paris.
