Marhuenda-Beltrán
Bio
I am currently a PhD student at Radboud University Nijmegen,
in the Digital Security Group in iCIS,
under the supervision of Bart Mennink (advisor) and Joan Daemen (promotor).
Before that, I did my Master Thesis at PQShield in Paris under the supervision of Raphaël del Pino and Thomas Prest.
My research focuses on symmetric cryptography including all aspects of cryptology and formal verification.
Nevertheless, I am interested in all areas of cryptography.
