About Me
I am a postdoctoral researcher in the Capsule team at Irisa, Rennes. My research field is code- and lattice-based cryptography. Previously, I was a PhD student in the COSMIQ team at Inria Paris under the supervision of Nicolas Sendrier and Jean-Pierre Tillich. During my PhD I worked on the design and analysis of new dual attacks against the decoding problem.
