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 availability and performance of large software systems.
- Hacker News , ,
- Discussions from HBase developers, which prompted a series of reactions to address the problems we mentioned in the paper.
- Twitter discussions: see this, this, and this (if you're looking for a screenshot that summarizes our paper, see this or this).
- Blog: neverworkintheory.org, Another word for it, Metadata, Fifty Quick Ideas to Improve Your Tests, Postmortem lessons, Agilezilla, Some discussions on Google+.
- And quite a few emails sent to us from developers...

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.
