About Me

Hi! I am a 4th year Ph.D. candidate of computer science at Tsinghua University, supervised by Prof. Shu-Tao Xia (home). I received both my BSc and MSc of Information Security from Southwest Jiaotong Univeristy, supervised by Prof. Xiaohu Tang (home).I'll also be supervised by Prof. Hongzhi Yin on recommender system during my academic visiting to The University of Queensland at the second half of 2024.
