I am an assistant professor and MTIS graduate director at the department of Electrical and Computer Engineering at the University of Victoria. Previously, I was an NSERC postdoctoral fellow at the Communication Security (ComSec) group in the department of Electrical and Computer Engineering, University of Waterloo and an NSERC Canada graduate scholar at Concordia University. My research interests focus on IoT security, Blockchains, and Lightweight cryptography.
