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.

Cryptanalyse par canaux auxiliaires

Best internship ceremony of the Foundation Mines-Telecom in Paris, 2017 May 27th [video]

This is a short French video presentation of the 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 some location measurements.


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 [internship report] [slides]
For other professional things, here is my LinkedIn.



Recognitions

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. Thanks' to Google's WomenTechmakers for offering a scholarship.
