Mulin Yu 于沐霖

I work on 3D vision, scene reconstruction, neural rendering, and structured geometric modeling. My recent research focuses on building digital worlds with both geometric precision and visual fidelity.

About

I am currently a Researcher at Shanghai AI Lab. Before that, I was a Postdoctoral Researcher in the IDC group at Shanghai AI Lab, working closely with Bo Dai and Dahua Lin. I received my PhD from INRIA in 2022 under the supervision of Prof. Florent Lafarge.

My work spans surface reconstruction, city modeling, novel view synthesis, and geometry-aware representations for realistic 3D understanding.
