I am currently a professor of the College of Intelligence and Computing at Tianjin University. Before that, I used to be a researcher in the Theory Lab of Hong Kong Huawei from May 2019 to Sept. 2021. In addition, I was a post-doc researcher in HKUST working with Prof. Kai Chen from May 2018 to April 2019. I received my B.E. degree and Ph.D degree (Advisor: Prof. Keqiu Li) both from the School of Computer Science and Technology, Dalian University of Technology, in 2012 and 2018 respectively. I was a research assistant in National University of Defense Technology from May 2014 to May 2015, under supervison of Prof. Deke Guo. From Oct. 2016 to Sept. 2017, I was a visiting student at the Department of Electrical and Computer Engineering in the University of Toronto, under the supervison of Prof. Baochun Li.
