Xiangjun GAO (高祥君)

I am a third year PhD candidate at (HKUST), supervised by Prof. Long Quan. Previously, I obtained my Master's and Bachelor's degrees in Computer Science from Beijing Institute of Technology (BIT). I am expected to graduate in 2027.

My research focuses on 3D Vision, including Avatar, 3D-Aware Video Model, 3D Agent, and 3D LLM. Previously, I interned at Microsoft Research, ByteDance , Tencent ARC Lab, and Huawei(London).
