🙋 I am Yijin Zhou (周艺晋), currently a second-year Ph.D. student at Shanghai Jiao Tong University and Shanghai Innovation Institute, supervised by Professor Junchi Yan and Research Scientist Jing Shao. I received my bachelor’s degree from Zhiyuan College, Shanghai Jiao Tong University, in 2024.

🔍 My research interests lie in AI agents, post-training, and trustworthiness. Outside of research, I enjoy 🏸badminton and 🏋️fitness.

💻 I am currently seeking industrial research/engineering internships related to agentic post-training. Always open to ☕️coffee chats, 💬scientific discussions, and 🤝potential collaborations—feel free to drop me an email!
