💫About Me

I am currently a second-year M.S.E. student at the ISPC Lab, Institute of Intelligent Vehicles, 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, Dynamic Reconstruction and Autonomous Driving Perception. In 2022, I was a research intern at OpenDriveLab of Shanghai AI Laboratory advised by Prof. Hongyang Li.

I’m also looking for research internship and Ph.D. (Fall 2025) opportunities, please feel free to drop me an email📬!
