Yuxi Xiao

I am a second-year Ph.D. student at the State Key Laboratory of CAD&CG, Zhejiang University, advised by Prof. Xiaowei Zhou. Currently, I am also a research intern at ByteDance Seed.

Developing 3D/4D foundation models for reconstruction and spatial perception (see my SpatialTracker series).
Defining and improving spatial abilities for multimodal large language models with 3D foundation models and principles of cognitive science.
Creating spatial AI agents capable of perceiving, manipulating, and learning from the real physical world.

I am open for collaborations. Please feel free to contact me if you are interested in my research.
