** I will be on the job market soon. I'm interested in any academic or industrial positions related to web search and information retrieval. You can find more about me here: CV (outdated).

Research Interests

     My mainly research interests focus on boosting the performance of information retrieval systems (i.e., web search engine). Particularly, most of my research projects are committed to improving the efficiency of Caching (especially, on architecture aware data intensive system) and Compression algorithms for text search. Besides, I am also involved in some projects that deal with string algorithms as well as GPU computing.

- Summer Intern in Web Search Group, Baidu Inc. (2011.07-2011.11)

  • Responsible for building a cache framework for posting lists:   

    • Analyze the characteristics of query term log in the real world web search engine.

    • Implement an efficient static cache framework which takes advantage of the observed characteristics.

    • Introduce a query term sampling mechanism which periodically provides feedback to the static cache module and helps the module to work efficiently.
