    I am now working as a scientist at Yahoo! lab. I did my final defense on Dec 2nd. 2013. Before joining Yahoo! lab, I was a PhD student in the Data and Information Systems (DAIS) Lab at UIUC. My advisor is Professor Kevin Chen-Chuan Chang. I received my Bacholer's degree in Computer Science ACM Honor Class from Shanghai Jiaotong University, China in 2007. Research My research interests include data mining, information retrieval, database system and machine learning. I enjoy building novel information systems and solving interesting and challenging research problems for realizing those systems. Now, I focus on building a novel social network monitoring system, and address many interesting problems, including crawling, indexing, and mining social network.
