I am a third year PhD student (accredited by ENS Paris) at Inria Paris-Rocquencourt under the direction of Karthikeyan Bhargavan in team Prosecco (Programming Securely with Cryptography). Our main research goal is to provide practical tools to analyze the security of sensitive web applications, especially those that use cryptographhy.

My research sometimes leads to the discovery of browser bugs. I found multiple attacks against Chrome, Firefox and Safari; most of which are listed on my OSVDB profile.
