ABOUT ME

UPDATE: As of August 2016, I am a Data Scientist at Uber. Please refer to my LinkedIn profile for the up-to-date information.

I received my Ph.D. from the Language Technologies Institute under School of Computer Science at Carnegie Mellon University in 2015 Dec. 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.

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.
