I am a Professor in the David R. Cheriton School of Computer Science at the University of Waterloo. I am affiliated with the CrySP (Cryptography, Security and Privacy) research group, and with the CACR (Centre for Applied Cryptographic Research).

In the Spring 2012 term, I am teaching CS 458/658 (Computer Security and Privacy) and CS 758 (Cryptography/Network Security).
