💫About Me
I am currently a second-year M.S.E. student at ISPC Lab of Tongji University and advised by Prof. Guang Chen. Before this, I obtained the bachelor’s degree in Vehicle Engineering at Tongji University.
My research interests mainly focus on 3D Computer Vision, including Dynamic Reconstruction, Generative Models and Autonomous Driving. In 2022, I was a research intern at OpenDriveLab of Shanghai AI Laboratory advised by Prof. Hongyang Li. From 2024, I interned at CCVL Lab of Johns Hopkins University advised by Bloomberg Distinguished Professor Alan L. Yuille. And I have been a visiting student at SU Lab of UC San Diego advised by Prof. Hao Su, where I spent a wonderful time in La Jolla.
Now I’m looking for Ph.D. (Fall 2025) opportunities, please feel free to drop me an email📬!
