Weiming Zhang

Master's Student @ SJTU (APEX Lab). Focus on LLM Agents, Reasoning, and Data Mining.

I am currently a second-year Master’s student at the School of Computer Science, Shanghai Jiao Tong University (SJTU). I am a member of the APEX Lab, privileged to be advised by Prof. Yong Yu and Prof. Weinan Zhang. Prior to this, I obtained my Bachelor’s degree in Computer Science and Technology from SJTU in 2024.

My research interests primarily focus on (M)LLM-based Agents, LLM Reasoning, and Data Mining. You can find my publications on Google Scholar.
