Welcome

I am Full Professor at the Universität der Bundeswehr München in its Department of Computer Science and Research Institute Cyber Defence (CODE), where I head the Privacy and Applied Cryptography (PACY) Lab. This is my private website.

My research and projects are on privacy-enhancing technologies underpinned by modern cryptographic methods and techniques. I am focusing on the design and analysis of cryptographic protocols and on their use to protect security and privacy in data processing, authentication, secure communications, and in decentralized, multi-party applications in the domains of social media, IoT, and blockchain. I am also teaching some of these topics on our Cyber Security MSc programme and supervising researchers.

Feel free to contact me if you are interested in collaboration or professional advice. For open positions in PACY Lab check here.
