I am a postdoctoral researcher in the Department of Computer Science at UIUC, working with Prof. Jiawei Han. I obtained my Ph.D. degree at KAIST under the supervision of Prof. Jae-Gil Lee. My research interests cover a wide range of topics in data mining, machine learning, and artificial intelligence. Specifically, I am interested in continuously learning knowledge from unstructured and/or evolving data.
