I am a third year PhD student 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.
Research
My research interest lies in natural language processing and machine learning. I have worked on the following topics:
- topic models and matrix factorization
- sentiment analysis and opinion mining
- word sense disambiguation
