Introduction

I am currently a full professor (since 2021/07) at Human Language Technology Research Center (HLT) at School of Computer Science and Technology at Soochow University. Before that, I had been an associate professor since 2016/07, and an assistent professor since 2013/07. I obtained my Bachelor, Master, and PhD degree from Harbin Institute of Technology (HIT) in 2006, 2008, and 2013, respectively, and joined Soochow Univeristy afterwards.
