About Me

Hi! I am Zixuan Chen (陈子璇). I am currently a Ph.D. Candidate at the School of Computer Science and Technology, Nanjing University (NJU). I am a member of the R&L Group, advised by Prof. Yang Gao and Assoc. Prof. Jing Huo.

Previously, I received my B.E. and M.E. degrees from Soochow University, School of Computer Science and Technology, under the supervision of Prof. Zongzhang Zhang. From Nov. 2024 to Nov. 2025, I was a visiting student at the National University of Singapore (NUS), working with Prof. Lin Shao.

🔬 Research Interests

My research focuses on Robot Learning, Reinforcement Learning, and Imitation Learning. I am particularly interested in:

• Long-horizon Manipulation: Leveraging prior knowledge (e.g., skill chaining, task decomposition) to solve complex, multi-stage tasks.
• Spatial Intelligence: Enabling robots to possess highly generalizable 3D spatial reasoning capabilities (e.g., 3D manipulation, world models).
