I am a fourth-year PhD student advised by Professor Shujian Huang at Nanjing University. My research focuses on LLM Reasoning, RL, and Multilingual LLM. Concurrently, I am a research intern at ByteDance Seed.

⭐ News

[2025-08-21] We are thrilled to introduce our latest breakthroughs: DuPO, a new preference optimization framework that enables LLMs to perform reliable self-verification and improvement without human annotation or oracle labels.Check out our paper for more details.

[2025-08-21] Our paper “R-PRM: Reasoning-Driven Process Reward Modeling” has been accepted on EMNLP2025 Main.

[2025-07-18] We are excited to open-source Seed-X, a 7B-parameter multilingual translation LLM that delivers performance comparable to leading closed-source models like Gemini2.5-pro.
