About

I'm Andrey, a doctoral researcher at the University of Luxembourg in the Cryptographic Protocols Group, advised by Dr. Andy Rupp. My work focuses on designing and analyzing cryptographic protocols with strong provable security guarantees, particularly in the context of privacy-enhancing technologies. In my free time, I enjoy travelling, reading, watching films, and playing squash. Feel free to reach out if you'd like to chat about research, potential collaborations, or just say hi!
