Hi, I am Luca. I am maître de conférences (the French equivalent of assistant professor) in the Computer Science department of Université de Versailles.
Being some kind of nerd, I am also interested in almost everything related to Information Technology. I am fluent in many programming languages, I enjoy learning new ones, and most of all I love mixing them in the context of web programming. Part of my passion for these subjects flows into the courses I teach, and the software I write in my (rare) spare time.
And, like most nerds, I tend to share out loud my thoughts on the things I like. You can read more about science, maths, computer science, web programming, etc. in my blog.

Nov 14, 2017: Invited talk at ECC 2017, here’s the slides.
I research and develop algorithms for finite fields and algebraic curves, usually with applications to cryptology in mind. I tend to put the stress on efficient algorithms, both in the theoretical analysis and the software implementation.
I am interested in computer algebra systems and expressive programming languages for doing mathematics. I like to use Sage in my investigations and I have distributed some software using it. I also am a member of the OpenDreamKit community, seeking to enhance the ecosystem of computational mathematics tools.
