Chao Zhang

I am a final-year Ph.D. student at the Computer Science Department of UIUC, under the supervision of Prof. Jiawei Han.

I am broadly interested in data mining and machine learning. My current research focuses on mining actionable knowledge from massive social sensing data and empowering intelligent applications. It falls in the intersection of social media analysis, spatiotemporal data mining, text mining, graph mining, and urban computing.
