I am an NSERC postdoctoral fellow with Prof. Guang Gong at the Communication Security (ComSec) group in the department of Electrical and Computer Engineering, University of Waterloo. Previously, I was an NSERC Canada graduate scholar with Prof. Amr M. Youssef at Concordia University. I am a member of the Center for Applied Cryptographic Research (CACR) at the University of Waterloo. My research interests focus on the design and analysis of symmetric key cryptographic primitives. Recently, I grew some intrest in the blockchain and smart contract technologies, and their applications in designing secure protocols .
