About Me ([GitHub] [Google Scholar]

I am currently an Associate Professor at the School of Data Science & Engineering, East China Normal University (ECNU). Before that, I was a research scientist at LARC, Singapore Management University (SMU). I obtained my Ph.D degree from School of Computing & Information System, Singapore Management University. I was trained (by my amazing supervisor Prof. Jing Jiang and secondary supervisor Prof. Feida Zhu) to be a NLP researcher. I received my Bachelor degree from the School of Mathematics and Statistics, Southwest University (SWU).

Research Interest

My recent research interest mainly includes knowledge bases, question answering, information extraction, text generation and deeep learning.
I am looking for self-motivated students with strong programming skill to work with me. Please read this FAQ before emailing me!
