What I look like

Hi, I am Édouard, a PhD student in computer algebra in the teams MIC2 (INFRES - Télécom ParisTech) and CRYPTO (LMV - Université de Versailles). I started my PhD in 2017, under the supervison of Luca De Feo, Hugues Randriambololona and Éric Schost.

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 !


Standard Lattices of Compatibly Embedded Finite Fields
ISSAC 2019
with Luca De Feo and Hugues Randriam.


I like to play with Sage or Nemo/Flint, and I developped some software using it. Details can be found in my GitHub repositories.

A Julia/Nemo library to make lattices of compatibly embedded finite fields.
A Julia/Nemo library containing algorithms for computing discrete logarithms in finite fields.
Library for computing normal bases based on Flint.


You can find more details in the dedicated section.

Other interests

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