Jiahe Jin

Hi 👋 I am a senior undergraduate in ACM Honors Class of Shanghai Jiao Tong University, majoring in Computer Science. Currently, I am a research intern at the CX Research Group in Carnegie Mellon University, advised by Prof. Chenyan Xiong. Previously, I was fortunate to work with Prof. Pengfei Liu at Shanghai Jiao Tong University.

My research interests include LLM agents, reasoning, and reinforcement learning. I am excited about building agents that learn through their own reasoning and experience, and with existing human knowledge.

I plan to pursue a Ph.D. in Computer Science, starting in Fall 2026. If you are interested in my research, feel free to contact me at zizi0123@sjtu.edu.cn!
