Sepehr Abbasi Zadeh's Home Page - Department of Computer Science

I completed my PhD in the Computer Science department of the University of Toronto, where I was advised by Yashar Ganjali in the Computer Systems and Networks group. Prior to my PhD, I was a member of the Theory group at UofT and finished my master's studies under the supervision of Allan Borodin and Aleksandar Nikolov. Before moving to Toronto, I obtained my BSc major in Computer Engineering and minor in Mathematics at Sharif University of Technology.

Research interests
