I'm a PhD student at the Department of Information Systems at University of Maryland, Baltimore County and advised by Dr. Shimei Pan in Text Mining and Social Media Analytics Lab. We mainly focus on social media-based user behavior and trait analysis. I was advisored by Dr. Malcom Gethers to work on feature location, impact analysis and software measurement tasks. My research interests include natural language processing, applied machine learning and software engineering. I obtained my Master Degree in computer and information science from Gannon University in 2013, advised by Dr. Frank Xu. I received my bachelor’s degree in Software Engineering from Nanchang Hangkong University, China. Before I started working for my master degree, I had worked as software engineer for 3 years in SNDA and RENREN Inc.
