I am a PhD student working in ENS Paris crypto team with an industrial grant from Thales. I'm studying post-quantum cryptography and cryptanalysis under the supervision of prof. Michel Abdalla (ENS) and prof. Henri Gilbert (ANSSI). For now, I mainly focus on lattice based and multivariate cryptanalysis. With this wide topic, I am glad to be also guided by Thomas Prest, Guénaël Renault and Sonia Belaïd.

If you are French and you would like to know what post-quantum crypto means, this 4 minutes summary is for you.

This is a short French video presentation of an internship I undertook in Thales.

Quantum geographic location

My advisors are in different locations in Paris. As a consequence, I am lucky to be working in a quantum superposition of several offices. This chart represents the location measurements of the last six months.

Curriculum Vitae

Before the PhD, I had the chance to work for Rambus Cryptography Research in San Francisco.
And before that, I studied in Telecom Paristech engineering school and made a double degree with the Parisian Master of Research in Computer Science where I interned with Thales crypto team [intership report] [slides]
For other professional things, here is my LinkedIn.


I have been very fortunate to receive recognition through scholarships and awards over the past few years. I am particularly thankful to my engineering school Telecom Paristech and its foundation Mines-Telecom. I also thank CHES Challenge 2016 organizers for offering me the chance to play with state of the art cryptanalysis hardware.

Personal things you might like to know

Aside from crypto, I like mathematics, quantum computing, computer science and coding in general. I'm interested in finding ways to make it accessible for all, particularly children. I invite you to have a look at the OLPC association or to try out Scratch, a pedagogical gold mine. I also try my best to struggle against the lack of women in scientific research. I went in Troyes high school in February as part of a women in science project. I was excited to share my experience with younger students!
I also enjoy other domains like anthropology, biology, ecology or history of science. During my spare time, I act in a theater company and I sing in a world music choir.
