I am a final-year Ph.D. student in Prof. Jiawei Han’s Data Mining Group (DMG) at University of Illinois Urbana-Champaign (UIUC). I obtained my M.S. in Computer Science and B.S. with a dual degree in Computer Science and Mathematics also at UIUC. My research interests lie in text mining, especially for mining structured knowledge from unstructured text data with minimal supervision.

I am joining Amazon AWS as an Applied Scientist in summer 2025.
