I am a postdoctoral researcher in the Computer Security Group at the Department of Information Technology and Electrical Engineering (D-ITET) at ETH Zürich. My research explores innovative techniques for securing computer hardware.

Before, I completed a PhD with Prof. Kaveh Razavi on the topic of software-inspired techniques for digital hardware security, preceded by a D-ITET MSc at ETH Zürich focusing on digital hardware design, that followed an Ingénieur Polytechnicien MSc curriculum in computer science and mathematics.
