About Me

Now, I am a research scientist in Bytedance America, and working with Dr. Kai Zhang and Dr. Li Zhang.

2024.10~2026.1, I am a postdoctoral researcher of Multimedia Computing & Communication (MCC) Lab at the University of Missouri - Kansas City, advised by Prof. Zhu Li, and working closely with Dr. Geert Van Der Auwera and Prof. Yiling Xu. My research interests include 3D Gaussian Splatting (GS) compact generation and compression, media quality assessment (i.e., 3D GS, 3D point cloud, and 3D mesh), and immersive media streaming.

2022.07~2024.04, I was a senior researcher in Tencent Media Lab, working with Dr. Joel Jung, Dr. Xiaozhong Xu and Dr. Shan Liu. My project includes 3D point cloud and mesh quality assessment.

I received my PhD from Shanghai Jiao Tong University (SJTU), and bachelor’s degree from Xidian University.
