Chao Zhang

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

My research falls in the area of data mining and machine learning, with special interests in text mining, spatiotemporal data mining, and graph mining. Currently, I am working on mining actionable knowledge from massive social sensing data to empower intelligent applications. I develop novel models, algorithms, and systems to tackle problems such as event detection, taxonomy construction, text cube construction, mobility modeling, and time series analysis; and explore their applications in smart city design, healthcare, cyber security, and IoT scenarios.
