About Me: Cheng Luo (罗成)

I am now working as a postdoctoral research fellow in THUIR group, Department of Computer Science and Technology in Tsinghua University, Beijing, China. My major research interests are in Web Search, Machine Learning and Natural Language Processing.

I got my PhD degree from Tsinghua University in 2017, supervised by Prof. Shaoping Ma and Prof. Yiqun Liu. I was a Visiting Research Fellow from Feb. 2016 to Jan. 2017 at Real Sakai Lab (酒井研究室) , Waseda University, supervised by Prof. Tetsuya Sakai. I have visited NExT Center for several times, supervised by Prof. Chua Tat-seng. At this moment, I serve as a co-PI at NUS NExT++ center now.
