About me
I am a 2nd year PhD student in the Inria/IMB CANARI team in Talence, France. My advisors are Alice Pellet-Mary and Renaud Coulangeon. I work on lattice-based cryptography, especially on the lattice isomorphism problem for structured lattices (module-LIP). You can download my CV here.

I am the guitarist in the metal band WarpDrive. Check out our album on Spotify!
WarpDrive is an Electro Symphonic Metal project based in Bordeaux (France) created in 2018. Blending the power of metal and electro with melodic and orchestral elements, WarpDrive's music is an invitation to an intergalactic journey, somewhere between the rigor of astronomy and the whimsy of science fiction.
