About Me

Hi! I am a four-year Ph.D. student at the Computer Science Department of UIUC, under the supervision of Prof. Jiawei Han. I am broadly interested in machine learning and data mining. My current research focuses on developing intelligent systems for modeling people’s activities in the physical world from massive space and time-coupled social media.

What’s New
