Biography

I am currently a 3rd-year Ph.D. candidate in the Galaxy Cluster Group at the Shanghai Astronomical Observatory, supervised by Prof. Shiyin Shen. Building on a foundation in probability theory and mathematical statistics, my research interests are astrophysics and computer vision, specifically transforming unstructured astronomical raw data into robust representations using low-level vision recognition. And my research interests also span 3D vision (NeRF, Gaussian Splatting), SLAM, and generative AI models. I hope to continuously update and expand my skill set within a dynamic R&D environment.
