Chao Xu
I am a UCLA Ph.D. candidate, currently a visiting graduate at UC San Diego, fortunate to be advised by Prof. Hao Su . Previously,
I received dual bachelor degrees in Computer Engineering from University of Illinois at Urbana-Champaign and Zhejiang University.
My research interests are focused on the fields of computer vision, robotics, and cognition. I actively engaged in pushing the boundaries of generalizable 3D vision: 1) object understanding, 2) 3D reconstruction and generation, etc.
I anticipate graduating in Spring 2025 and am on the job market, seeking full-time opportunities. Please feel free to contact me.

We propose a new pipeline in the One-2-3-45's paradigm: More consistent multi-view generation (Zero123++) and better reconstruction (multi-view conditioned 3D native diffusion models).
