I am a sixth 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, including operating systems, database systems, and distributed systems. My CV is here. I'm on the academic job market! Here are my research statement and teaching statement.
