Biography

I am currently a 2rd-year Ph.D. candidate at Galaxy Cluster Group, Shanghai Astronomical Observatory, supervised by Prof. Shiyin Shen. I received my M.S. degree from College of Probability theory and mathematical statistics, Yunnan Minzu University, in 2023. Before that, I received my Bachelor degree from the College of Mathematics and applied mathematics, Zhejiang International Studies University, in 2020. My research interests include galaxy morphology, computer vision, and 3D vision (Nerf and 3DGS).
