About me
I'm an Associate Professor of cryptography in the Department of Combinatorics & Optimization at the University of Waterloo in Waterloo, Ontario, Canada. My research focuses on improving the security of Internet cryptography protocols such as SSL/TLS and SSH, and developing practical quantum-resistant cryptosystems.
Research
My research interests include:
- Applied cryptography: key exchange protocols; post-quantum cryptography; digital signatures; public key encryption; client puzzles / proofs of work; elliptic curve cryptography; quantum cryptography
- Internet security: network security protocols (SSL/TLS, SSH, Tor, …); public key infrastructure (PKI); authentication

Pictures
I'm fortunate to be able to travel a lot. I take lots of pictures on my trips. The best of my photos are posted in my galleries. My most recent galleres are:
