Hi there! I'm a final-year PhD candidate at Zhejiang University advised by Prof. Lu Yu and Prof. Yiyi Liao. My research interests lie at the intersection of 3D computer vision and visual data compression.

My long-term research goal is to enable photorealistic, compact, and real-time 6-DoF interactive video streaming applications on mobile devices. This goal involves three key research challenges: efficient scene representation design, efficient compression, and real-time rendering. My previous work addresses these challenges through accelerated rendering and efficient compression of high-fidelity neural radiance fields. Currently, my research focuses on dynamic scene representation and compression with 3D Gaussian splats, supporting real-time interactive free-viewpoint video on edge devices.
