I am a guest researcher at the Chair of Security Engineering, Ruhr University Bochum, Bochum, Germany. I investigate the security of cryptography implementations against side-channel attacks.
In 2017, I completed a Master's Degree at Télécom SudParis, in telecommunication engineering, with a specialization in network and system security. I am currently finishing my doctoral studies at RUB.

My research interests are:

• Cryptography
• Side-channel attacks
• Formal verification of masked implementations
