About Me

I am currently a fourth-year Ph.D. student at the Department of Electronic Engineering, The Chinese University of Hong Kong(CUHK), supervised by Prof. Hon Ki Tsang. Before that, I received my Bachelor degree in June 2020 at the School of Optical and Electronic Information(OEI), Huazhong University of Science and Technology(HUST).
My current research interests lie in Silicon Photonics, integrated spectrometer and optical phased array.
