Me in brief:

I'm a PhD student with great interests in linear algebra and arithmetics, working on their applications in quantum computing, in the domain of password recovery and preimage search. I'm passionate and love presenting my results, as well as teaching cryptography to my students.

Short Bio

After a scientific high school cursus, and one year of preparatory classes, I decided to take a break from physics and follow a deeper exploring of computer science. I passed the generalized math and compsci degree at Paris Diderot (P7), then their math and compsci Master in cryptography and cybersecurity (MIC). The master ended with an internship at Gendarmerie Nationale about classical password recovery for judiciary forensics. The success of this internship led to a thesis offer for my current research.

Research Interests

As a PhD student, I'm working on password recovery and hash function preimage search on quantum hardware. My goal is to provide precise and exact quantum memory and operation costs for bruteforce or dictionary attacks on hashed passwords using quantum hardware.

Teaching

I animate exercises sessions for the CHIFR course for 2026.
