I'm a fourth-year Ph.D. student at Peking University, under the supervision of Prof. Gang Zeng.

My research interest is in 3D Computer Vision, with a specialty in 3D reconstruction and generation.

I was born in Shandong, China. During 2016-2020, I'm fortunate to spend my undergraduate days in the School of Life Sciences at Peking University. I started to double-major in Computer Science in 2017, and found myself enjoying coding more.
After that, I joined the Key Laboratory of Perception (MoE), School of AI, as a Ph.D. student from 2020.

I love the process of implementing something (maybe anything).
Apart from coding, I am also passionate about animes, comics, games and (mainly sci-fi) novels.
I have finished both Divinity: Original Sin 1 and 2 in tactician mode. My favorite book series are Tales of Tarsylia.
