Researching on Cryptology at the Centrum Wiskunde en Informatica (CWI) in Amsterdam (Netherlands).

Completing a postdoc in Cryptology at the Centrum Wiskunde en Informatica (CWI), I defended my PhD at the école normale supérieure (ENS) of Paris in 2024, advised by Pr. David Pointcheval.

My research interests are focused on post-quantum Cryptology and protocols with advanced functionalities, with works on lattice Cryptanalysis, Traceable Receipt-Free Encryption, Verifiable Computations on Homomorphic Ciphertexts, Functional Encryption, Registration-Based Encryption and Key-Encapsulation Mechanisms. I have also worked on Technical Specifications for post-quantum Cryptography at the European Telecommunications Standards Institute (ETSI) during my PhD on behalf of Cosmian.
