Juzheng Zhang's Profile Image

I am a 2nd-year PhD student in Computer Science at the University of Maryland, College Park, advised by Prof. Tom Goldstein. My research focuses on post-training methods for LLMs and agentic systems, with an emphasis on RL-based alignment and continual learning to improve reasoning reliability and enable stable self-improvement over time. Before joining UMD, I graduated with honors from Shanghai Jiao Tong University, where I earned a Bachelor’s degree in Information Engineering.

I am currently seeking research internship opportunities for summer 2026. Feel free to reach out! 🤝
