I am currently a second-year Master’s student at National Engineering Research Center for Software Engineering, Peking University. Previously, I had the fortune to collaborate with researchers from NEUIR, THUNLP, ModelBest(面壁智能) and Shanghai AI Lab. My research interests include Code Intelligence, LLM Reasoning, and LLM Agent.

I am looking for PhD opportunities, feel free to contact me!🔥
