I am currently a fourth-year Ph.D. student at the Department of Information Engineering, The Chinese University of Hong Kong, supervised by Prof. Angela Yingjun Zhang. Before that, I received the B.Eng. degree from the Yingcai Honors College, University of Electronic Science and Technology of China in 2021. I work closely with Prof. Xiaojun Yuan during my undergraduate and postgraduate studies.
My research interests lie in the next-generation wireless communication technologies, including but not limited to semantic/task-oriented communications, wireless edge intelligence, and reconfigurable intelligent surface (RIS) assisted communications.
