I am a master's student in Data Science and Engineering at Zhejiang University (Sept. 2024 - Jul. 2027 expected), advised by Prof. Wei Chen at ZJUVAI within the State Key Laboratory of CAD&CG. Before joining Zhejiang University, I received my B.Eng. degree in Computer Science from Jinan University. My research focuses on LLM-based autonomous agents, especially multi-agent collaboration, autonomous evolution, latent-space communication and reasoning, autonomous evaluation, and reasoning-oriented post-training.

I am currently a Talent Program intern at ByteDance, working on LLM post-training, preference alignment, interactive evaluation, and high-fidelity human-like agent simulation for SFT and RLHF/DPO data generation. Previously, I worked as a research intern at Alibaba Group's Future Living Lab and as a research assistant at THUNLP, Tsinghua University, working with Prof. Zhiyuan Liu, where I contributed to the ChatDev project.

Prospective PhD applications: I am actively seeking Ph.D. positions starting in Fall 2027. I am especially interested in labs working on foundation models, LLM agents, multi-agent systems, autonomous evolution and evaluation, latent-space communication and reasoning, and post-training. Please feel free to reach out if my background may align with your group.

Prospective research internships and collaborations: I am looking for research internship or collaboration opportunities around LLM agents, multi-agent systems, and latent-space communication.
