Chi Wang

PhD Candidate,


Personal Links

I am a Computer Science PhD candidate in  Database and Information Systems Lab (DAIS)  group at UIUC. I work in Data Mining Research Group, and my advisor is Professor Jiawei Han.

I received my Bachelor of Engineering in 2009 from Tsinghua University, Beijing. 

My research interest has an emphasis in information network analysis and mining, especially in revealing latent entity structures to reorganize information in a more human-friendly way.
