About Me

I am Songchun Zhang (张菘淳), a first-year Ph.D. student at MMLAB@HKUST, supervised by Prof. Anyi Rao and Prof Huamin Qu. I obtained my master’s degree at Zhejiang University, where I collaborated with Prof. Wei-Wei Xu and Prof. Changqing Zou. Previously, I received my Bachelor’s degree from Hunan University.

My research focuses on 3D/4D content generation and world model:

  • Generalizable 3D Foundation Models: Generative 3D reconstruction from sparse, multi-view, or in-the-wild data.
  • Interactive World Models: Real-time inference and control with Long-term memory.
