I am an Assistant Professor in the Electrical and Computer Engineering Department, University of Toronto. I joined the department in January 2013, after I received my Ph.D from the Computer Science Department of University of Illinois, Urbana-Champaign under the supervision of a great advisor, Yuanyuan Zhou. From 2009 to 2012 I was also a visiting student in the awesome System and Networking group of University of California, San Diego. I received my B.E. from Beihang University in July, 2006. My CV is here.
(New) I am looking for self motivated students to work with me. If you are interested, please submit your application here.
My research interest is software systems and operating systems, with a focus on developing practical solutions to improve the reliability and availability of large software systems. My Ph.D. dissertation research focuses on improving the diagnosis of software failures via better design and use of log messages.

I do a lot of sports, including basketball, swimming (pool and open water), skiing, and running. I served as captain of the Beihang's CSE basketball team and co-captain of the UIUC CS faculty & grad-student basketball team in the intramural games. I also ran some marathon and half-marathons (see a recent photo here). When I have more time, I also play accordion.
