I am currently working at Yahoo! Labs as a Scientist, focusing on problems related to computational advertising (e.g., behavioral targeting).

Before joining Yahoo, I was a Postdoctoral Researcher at IBM Almaden Research Center (01/2007-06/2009) working on privacy-preserving social-network analysis and text analytics. My contributions to these projects have won me five IBM Invention Achievement Awards (five patent filings) , one IBM Invention Plateau Award and one IBM Bravo Award.

I received a Ph.D. degree in Computer Science from University of Maryland Baltimore County (USA) in 2007, and a B.S. in Computer Science from Nankai University (China) in 2001. My research interests include privacy-preserving data mining, social-network analysis, text analytics, distributed data mining and statistical machine learning. I have authored or co-authored 20+ peer-reviewed papers and book chapters in these areas. I regularly serve on the program committee of many data mining conferences (e.g., KDD, ICDM, PKDD, PAKDD), and as a reviewer of many scientific journals (e.g., IEEE TKDE, ACM TKDD). I am also maintaining the Privacy-preserving Data Mining (PPDM) Bibliography, one of the most popular PPDM paper repositories in the research community.
