Welcome to my home page!

 

I am a Ph.D. student in Mathematics at the University of Bordeaux in the LFANT team, under the supervision of Damien Robert and Aurel Page, since September 2018.

My research interests lie at the intersection of computational number theory and algebraic geometry. The goal of my thesis is to obtain a faster point-counting algorithm for abelian surfaces using isogenies, generalizing the well-known SEA algorithm for elliptic curves.

I am a former student of the École normale supérieure (ENS) in Paris. My master's thesis is about key-exchange protocols from ordinary isogeny graphs, and was supervised by Luca De Feo and Benjamin Smith from the INRIA team Grace in Saclay. I also did a six-month internship in the Thales crypto team, where I implemented a finely-tuned version of the SEA algorithm in C.

 

You can find here a list of publications and other works, as well as contact and personal information.

 

With the other board members of the Math PhD association Lambda, I organize the Lambda seminar at IMB: if you wish to give a talk, send me an email!
