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 !

## Papers

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

## 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.

**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.

## Teaching

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.
