I am a second-year master's student in Computer Science at Zhejiang University. I currently work with Prof. Wei Chen at ZJUVAI within the State Key Laboratory of CAD&CG. I am also an LLM Algorithm Intern at ByteDance (Jindouyun Talent Program), following a fulfilling internship with the Taowise team at Alibaba.

Previously, I received my Bachelor's degree from Jinan University. I also served as a research assistant on the ChatDev project at Tsinghua University, advised by Prof. Zhiyuan Liu and Prof. Chen Qian.

Prospective PhD programs: Seeking Ph.D. positions for Fall 2027. Open to collaborations & recommendations.
Prospective interns: Seeking Research Interns for LLMs & Autonomous Agents. Email me.

Research Focus: Designing LLM-based autonomous agents that collaborate effectively to tackle complex tasks (software development, self-evolution, and latent-space reasoning/communication).
