I am currently a joint Ph.D. candidate of Shanghai Jiao Tong University and Monash University from SEIEE since 2021, working with Prof. Weiyao Lin, Prof. Jianfei Cai and Prof. Mehrtash Harandi. Before that, I spent 4 wonderful years studying at Dalian University of Technology as an undergraduate student since 2017 (top 5%). My research interests include NeRF/3DGS compression, image/video compression and computer vision. Here is my CV/Resume. I am also happy to share my good friend Qianyi Wu’s fantastic works here.
If you are interested in my work, please contact me via yhchen.ee@sjtu.edu.cn.
