What's New
  • Oct 2016: I have joined IBM Research-Almaden as a research scientist!

About Me

I am now a research scientist in IBM Research-Almaden. I received my Ph.D. degree from Institute of Network Computer and Information System, School of EECSPeking University. My supervisor was Prof. Ming ZhangI was also a joint Ph.D. student at Database and Information Systems LabDepartment of Computer ScienceUniversity of Illinois at Urbana-Champaign. I was supervised by Prof. Jiawei Han at Data Mining Research Group.

Research Interests

Natural Language Understanding, Knowledge Discovery and Machine Learning. The goal of my research is to help real world applications in human daily life with better intelligence. As one crucial step towards this goal, I am now researching augmented shallow semantic parsing with intelligence-in-the-loop learning for better natural language understanding.
