About Me

Hello! 😊 I’m a third-year PhD candidate at The Chinese University of Hong Kong (CUHK) in the Department of Computer Science and Engineering, supervised by Prof. James Cheng. My research interests include Agentic Reinforcement Learning, Visual Language Models, and Machine Learning Theory.

On the application side, I am interested in building the efficient and effective agent systems, especially in real-world, multi-turn settings using a reinforcement learning approach. On the theory side, I have done research on graph neural networks and attention mechanisms supervised by Dr. Yifei Wang at MIT CSAIL. I have also collaborated closely with Dr. Xinyi Wu at MIT IDSS and Dr. Kevin Qinghong Lin at Oxford Torr Visual Group.

Prior to coming to CUHK, I was an undergraduate student at Harbin Institute of Technology, where I worked as a research intern at SCIR, supervised by Prof. Libo Qin.

If you are seeking any form of academic collaboration, please feel free to email me at wjqkoko@gmail.com.

Expected to graduate in Fall 2027. I am currently looking for internship opportunities or full-time roles starting late 2027. Please feel free to reach out!
