I am a PhD candidate affiliated with INRIA Bordeaux and Institut de Mathématiques de Bordeaux in isogeny-based post-quantum cryptography. My supervisors are Benjamin Wesolowski, Damien Robert and Luca De Feo.
My research interests are related to isogeny computations in dimensions one and higher along with cryptographic applications. I have contributed to improvements of the SQIsign digital signature scheme relying on the efficient computation of dimension 2 and 4 isogenies.
