I am a freshly-minted PhD, currently working as an engineer at LORIA‘s team CARAMBA on symmetric cryptography. More specifically, I am interested in the design and the analysis of lightweight encryption algorithms. I have been studying these primitives for the last 3 years as part of my PhD, under the supervision of Marine Minier. My thesis can be found here, and the slides here.

Below is a summary of my work. You can also download my resume here.
