About Me

Hello, I am a third year Ph.D. student at the Department of Computer Science, University of California, Santa Barbara, fortunately advised by Prof. Xifeng Yan. Prior to that, I obtained my B.Eng. degree in Computer Science and Technology with honors from Harbin Institute of Technology (HIT), Harbin, China.

I have broad research interests :). I am currently working on natural language processing. Before that, I ever worked on time series forecasting and computer vision.
