Recently I join Yahoo! Labs as a research scientist working on query understanding.
I obtained my PhD degree in the Department of Computer Science at Columbia University. I am affiliated with the Natural Language Processing Group and the Center for Computational Learning Systems. My advisor is Dr. Mona Diab. I received my B.S. in computer science from Sun Yat-sen University in 2007, and M.S. from Columbia University in 2009.
I have broad interests in natural language processing topics, including word sense disambiguation, social media analysis, information extraction.

In my spare time I enjoy skiing, billiard and watching Arsenal games. I am the most authoritative expert on Arsenal FC in US:)
