Xinhao Ji | 姬歆淏

I am a visiting student at MMLab@NTU, where I am fortunate to be advised by Prof. Ziwei Liu. I am also an undergraduate at the School of EECS@PKU, expected to graduate in June 2027. Previously, I was fortunate to work under the guidance of Prof. Dingwen Zhang and Prof. Zhihang Zhong. My research interests lie in 3D vision and physical AI.
