- 👋 Hi, I’m @Hakim Fang, a Computer Science Ph.D. candidate in a joint program at Zhejiang University and Westlake University.
- 👀 My research interests have shifted from AIGC to embodied intelligence.
- 🌱 I’m currently working on world-action models and exploring how general-purpose AI can interact with the physical world.
- 📫 Feel free to reach me at fangxueji@zju.edu.cn.
