Biography

I am an engineer at XGRIDS, mainly responsible for 3D reconstruction, especially work related to 3D Gaussian Splatting (3DGS). Before that, I received my bachelor's and master's degrees from IIPL Lab of Hangzhou Dianzi University, supervised by Prof. Chenggang Yan from HDU and Ming Lu from Intel Labs China.

News
