Short Bio

I am a third year Ph.D. student in Prof. Jiawei Han's Data Mining Group, Department of Computer Science, University of Illinois at Urbana-Champaign.

My research focuses on constructing multi-faceted taxonomy from massive unstructured text corpora, to facilitate semantic search and mining of large domain-specific corpora. My works lay in the intersection of data mining, natural language processing, and information retrieval.

Before I joined UIUC, I got my bachelor degree from Shanghai Jiao Tong University, and was a member of IEEE Honor Class.
