Short cv (updated on 01/02/2021).

I work mainly in the field of algebraic coding theory. Several of my papers deal with self-dual codes and their automorphisms, with a particular focus on extremal codes. More recently, my research has focused on two families of linear codes, namely G-codes (which are quasi-cyclic codes with other symmetries) and minimal codes. Both families have interesting connections with other areas of mathematics, such as representation theory, finite geometry and combinatorics, as well as possible applications in cryptography. During my academic career, I have also been interested in problems on Euclidean lattices, on Möbius function of subgroups and on the arithmetic of finite fields.
