About Me

I'm Sicheng Fan, a Master's student at Fudan University, researching Computer-Use Agents, Hybrid Agents, and Reinforcement Learning. I serve as Technical Lead at WebAgentLab and Researcher at Qwen, Alibaba. I am dedicated to building intelligent agent systems capable of autonomously operating graphical interfaces, with research published at top-tier conferences including CVPR and ICLR.

I actively contribute to open source and aim to advance computer-use and hybrid agents through shared research and tools. Feel free to reach out for collaboration!
