Xiyu Zhang 张喜瑜

I study how machines can reconstruct, understand, and imagine the spatial world.

I am a third-year PhD student in the College of Computer Science at Zhejiang University, working with the ZJU3DV group under the supervision of Prof. Guofeng Zhang.

My research spans 3D/4D reconstruction and understanding, with a current focus on generative world models and 3D generation.

Looking for a research internship I’m seeking internship opportunities in world models, 3D generation, and spatial intelligence. Get in touch
