ABOUT

Hi, I’m Jiayu.

I am a master’s student in Computer Science at the Institute of Computing Technology, Chinese Academy of Sciences (ICT, CAS). My research focuses on multimodal large language models, AI agents, and reinforcement learning.

I am particularly interested in training agents to solve long-horizon tasks and improving the reliability and alignment of multimodal models. I study how reinforcement learning, better task environments, and robust evaluation can help models reason and act more effectively.

I am currently a research intern at JD.com, working on multimodal safety models and long-horizon code agents.

Beyond Research

Beyond research, I enjoy playing the violin, table tennis, swimming, and debate. These interests give me space to stay curious, focused, and connected with people outside the lab. I am always happy to meet like-minded friends—whether you would like to exchange research ideas, play a game of table tennis, make music together, or simply have an interesting conversation, please feel free to reach out.
