Biography

I am currently a Ph.D. student in the School of Aeronautics and Astronautics, Sichuan University (SCU), supervised by Prof. Songchen Han. I obtained my B.E. and M.S. degrees from Sichuan University in 2020 and 2023, respectively.

From Jan. 2022 to Dec. 2025, I was working as a research intern at Megvii Technology (Megvii Research Chengdu), supervised by Prof. Shuaicheng Liu, Dr. Yuhang Lu, Dr. Ao Luo, and Dr. Haipeng Li.

My research interests include image restoration and image alignment, especially low-light image enhancement and homography estimation.
