Jingkun An | 安璟坤

I am a Research Assistant at the School of Computer Science, Peking University (PKU) . Previously, I also received my Bachelor's degree from Beihang University in 2024. During my two internships at Peking University, I was honored to be advised by Dr. Yemin Shi and Prof. Shanghang Zhang, respectively.

Currently, my interest lies in Embodied Agents, which are at the intersection of Multimodal Large Language Models and Embodied AI, with particular interests in high-level planning and low-level control with spatio-temporal intelligence, working towards an generalist agent in a complex real-world environment. Representative works are highlighted.
