Hi, I am Édouard, I hold a teaching position (ATER) in the mathematics department of Université de Versailles since September 2020.
I am curious about almost everything related to mathematics, computer science, and teaching. My main domains of interest are computer algebra, algorithmic number theory, and cryptology. On top of that, I like to spread the idea of free software and free licenses in general.
If you want to know more, you can send me an e-mail!

Software
I like to play with Sage or Nemo/Flint, and I developped some software using it. Details can be found in my GitHub repositories.
- TriSym
- A Julia/Nemo library to compute trisymmetric decompositions for the multiplication in finite fields.
- LatticeGFH90
- A Julia/Nemo library to make lattices of compatibly embedded finite fields.
- DlogGF
- A Julia/Nemo library containing algorithms for computing discrete logarithms in finite fields.
- normalBases
- Library for computing normal bases based on Flint.

Other interests
I also practice and teach improvisation theatre, that is why you can also find ressources (in French) about some “lessons” I gave.
