I currently work on computational techniques for the decryption of historical documents.
I obtained my master's degree in 2025, in the fields of cryptology and high-performance computing at Sorbonne Université (CCA curriculum).
My end-of-studies internship focused on the theoretical complexity of quantum algorithms, under the supervision of Alex B. Grilo and Damien Vergnaud at LIP6. Against a quantum adversary, the conditions for secure zero-knowledge proofs change. Our work involved the theoretical analysis of languages that admit zero-knowledge proofs with constant-depth simulators. In a post-quantum setting, we contribute towards proving that the existence of such a simulator implies language membership to BQP. [report], [slides], [poster]
