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. Prior to UIUC, I received my bachelor degree from Shanghai Jiao Tong University, under the supervision of Prof. Xinbing Wang, and I was a member of IEEE Honored Class.

My research focuses on learning faceted taxonomy from massive unstructured text corpora for constructing structured knowledge base, on which actionable knowledge can be further uncovered to power intelligent services and applications. My works lay in the intersection of data mining, machine learning, information retrieval, and natural language processing.
