I am a PhD student at the Visual Computing & Artificial Intelligence Group at the Technical University of Munich, working with Prof. Matthias Nießner. I received my Master’s Degree in Computer Science at ShanghaiTech University in 2022, advised by Prof. Shenghua Gao. Before that, I obtained my Bachelor’s Degree in Automation at Hunan University in 2019. Homepage.
GaussianAvatars: Photorealistic Head Avatars with Rigged 3D Gaussians |

CVPR 2024 |
We introduce GaussianAvatars, a new method to create photorealistic head avatars that are fully controllable in terms of expression, pose, and viewpoint. The core idea is a dynamic 3D representation based on 3D Gaussian splats that are rigged to a parametric morphable face model. This combination facilitates photorealistic rendering while allowing for precise animation control via the underlying parametric model. |

SIGGRAPH'23 |
We propose NeRSemble for high-quality novel view synthesis of human heads. We combine a deformation field modeling coarse motion with an ensemble of multi-resolution hash encodings to represent fine expression-dependent details. To train our model, we recorded a novel multi-view video dataset containing over 4700 sequences of human heads covering a variety of facial expressions. |
