My main interests are in cryptography, computational number theory and computer algebra. My research focuses on the computational aspects of Euclidean lattices and their applications in cryptography. One of the attractive properties of lattice problems is their conjectured quantum intractability: this makes lattice-based cryptography a viable option for post-quantum cryptography (which should not be confused with the less mature field of quantum cryptography). See here for a gentle introduction to post-quantum cryptography with a lattice focus, and here for the main post-quantum crypto standardization effort.

I'm also a member of the editor boards of Journal of Cryptology and Designs, Codes and Cryptography.

For my habilitation and PhD theses, see the dedicated pages: HDR, PhD.
