My Email

I am currently the CTO of SF Express business group, an express delivery company based at Shenzhen, China.

Previously I was a software engineer at Google working on web crawling and indexing for Google search and later social infrastructures which power Youtube/Blogger comments, G+, hangout, photos etc.

I received my Ph.D from UC Davis in June 2010. My advisor was Dr. Felix Wu. I also got a lot of advice from Dr. Norm Matloff, Hao Chen, Raju Pandey, and Michael Gertz.

Fun fact: my Erdős number, if you know what it means, is 4, through the path of Paul Erdos - Ron Graham - Tom Leighton - Fred Chong - me.


    • Ph.D, Computer Science, University of California, Davis. Advisor: Dr. Felix Wu (Received in Jun. 2010)

    • M.S., Computer Science, University of California, Davis. (Received in Sep. 2008)

    • M.S., Electronic Engineering, Tsinghua University, Beijing, China. Advisor: Dr. Xing Li. (Received in Jan. 2005)

    • B.S., Electronic Engineering, Tsinghua University, Beijing, China. (Received in Jul 2002)


My research focuses on Web related issues, particularly search engines and online social networks.

During my Ph.D study at UC Davis, most of our research projects are under the large umbrella of Davis Social Links. I looked at the following issues.

  • Online social network crawling and estimation

  • Message propagation and social influence measurements

  • Online privacy and trust management

My past research projects in Tsinghua University are listed as follows. Most of them were done as part of Compass Search.

    • Link Analysis:

        • Accelerated PageRank Algorithm

        • Distributed PageRank Computation

    • Web Crawler:

        • High performance crawling: I developed a distributed web crawler as a senior.

        • Crawling policy: a) server politeness. b) web page quality. c) crawling coverage.

    • Webpage Classification: Our Compass team took the first place in Chinese Web Page Categorization Competition, April 2003.

    • IPv6 Web Evolution and Performance Analysis: I monitored the evolution of more than 1,000 IPv6 Web sites from 2001 to 2005. Here is our IPv6 search engine.

During my graduate study in Tsinghua University, I interned at Microsoft Research Asia several times and worked on large scale duplicate document detection.
