Chi Yan

I am currently a Ph.D. student under the supervision of Prof. Dan Xu, at Hong Kong University of Science and Technology (HKUST). I received my Bachelor's Degree from Northwestern Polytechnical University (NWPU) in 2022.

My research focuses on 3D scene recoreconstruction and perception based on NeRF and 3DGS.
