ABOUT ME

I am currently a PhD student in the Language Technologies Institute of School of Computer Science at Carnegie Mellon University. I have defended my dissertation on October 2, 2015 and expected to receive my Ph.D. by the end of 2015. My advisor is Professor Robert E. Kraut (Human Computer Interaction Institute). My thesis committee includes William Cohen (Machine Learning Department), Eduard Hovy (Language Technologies Institute), and Moira Burke (Facebook).

My research interests are to combine social science theories, language processing technologies, and machine learning methodologies to statistically analyze large-scale data and understand communication dynamics in online social environments. In online environments, people rely heavily on language to communicate with others and accomplish their social goals (e.g., presenting themselves appropriately in social networking sites, attracting followers in social media, or eliciting support in health support groups). People generate a large volume of text online every day, so we need sophisticated approaches to automatic language analysis in order to understand how people accomplish these goals and further design interventions to help people achieve them.

For the past few years, my research has focused on investigating how people use language to communicate with others online and its effects on social outcomes. In one line of research I conducted several studies to inspect self-presentational language in social networking sites (e.g., Twitter and Facebook) and its effects on growth in social network size, audience responsiveness and development. In another line of research I examined how individuals present themselves to acquire support in online health support groups and how the support produced in these groups influences group and health outcomes, such as membership commitment and user satisfaction. These projects advance our understanding of computer-mediated communication and provide guidance for practitioners to improve their services.

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, data science, analysis of social media, information extraction, natural language processing, and database.

    PROFESSIONAL EXPERIENCE

    2006.09-2015.12 Research Assistant, Carnegie Mellon University, Pittsburgh, PA, USA
  • Representative project: Conversational Dynamics in Online Support Groups

    This goal is to understand how conversations in online support groups produce social support at the level of the conversational episode and how the support produced in these groups influences group and health outcomes, including members’ commitment to the groups and their health quality of life. My role was to develop machine learning models to enable fast and accurate automated coding of the conversation contents in online support groups and use statistical methods to analyze machine-coded data and infer the underlying mechanisms of social interactions. Under supervision of Prof. Robert E. Kraut and Prof. John M. Levine.

    INTERESTS

    All my interests involve food!

    I love to travel to try new food. People use different ways to remember the cities they've visited. I like to mark a city with food.

    I also enjoy cooking. Cooking relaxes me and releases my stress. Moreover, it is like doing science and conducting experiments, with the goal of finding a combination of ingredients that taste good. I have learned to cook some traditional cuisines of different countries, such as Italy, Japan, Korea, and Thai. The next one I like to learn is Indian cuisine.

    Following are some pictures of me eating around the world and food I cooked.
