I am a PhD candidate in the David R. Cheriton School of Computer Science at the University of Waterloo, Canada. My advisor is Professor Douglas Stinson. My research interests lie in cryptography, security, game theory, and algorithms. I have received my MSc in computer science from the School of Electrical Engineering and Computer Science at the University of Ottawa under the supervision of Professor Timothy Lethbridge in the area of software engineering.
