Zeyan Zhuang (庄泽琰)

About me

I am a fourth-year Ph.D. candidate in electronic and computer engineering at the Hong Kong University of Science and Technology (HKUST), under the supervision of Prof. Shenghui Song. Prior to this, I received my B.Eng. degree in intelligence science and technology from Nankai University (NKU), Tianjin, China, in 2022.
My research interests include random matrix theory, information theory, and their applications in wireless communications, signal processing, and data science.
