I'll be joining the Khoury College of Computer Sciences at Northeastern University as an assistant professor in Fall 2025. I'm looking for motivated students to start in Fall 2025!
I am a final year PhD student in the Department of Electrical and Computer Engineering (ECE) at the University of Toronto. My advisor is Ding Yuan. I received my M.A.Sc (March 2018) and B.A.Sc. (June 2015) with Honours from the same department. I'm interested in improving the performance and reliability of software systems. My CV is here.
