Short Bio

A concise research-focused introduction.

I am a PhD student at Nanyang Technological University (NTU), advised by Prof. Jianfei Yang. My research focuses on multimodal foundation models and agents for embodied intelligence, particularly embodied reasoning, vision-language-action models, world models, and robot learning. I received my B.Eng. in Computer Science from Taishan College at Shandong University, where I worked with Prof. Xuemeng Song, and I have been a research assistant at the Intelligent Media Research Center (iLearn), led by Prof. Liqiang Nie. I am also a research intern at Alibaba DAMO Academy, developing open embodied models and systems.
