RESEARCH

My research interests include using language processing technologies and machine learning methodologies to investigate and analyze social behavior in online environments. Currently, I am particularly interested in two social computing problems. One is how to develope an audience in online communities or social networking sites (e.g., Twitter). Another is to understand the consequences of online social support, including membership commitment and health quality of life. My advisor is Robert Kraut.

The focus of my previous research was on question answering and information retrieval. In general, the related fields of my research interests include social computing, analysis of social media, information extraction, natural language processing, and database.
