About

I am an undergraduate student in Computer Science at the School of Electronics Engineering and Computer Science, Peking University. Since April 2025, I have been conducting undergraduate research in embodied AI and robot navigation under the guidance of Prof. He Wang.

My current research focuses on embodied navigation, multi-view vision-language-action models, spatial awareness, reinforcement learning, and sim-to-real validation. I am also interested in long-horizon mobile manipulation, navigation-manipulation coordination, multimodal world models, and robot generalization.
