A Master student in Peking Univrersity. My primary research interest is LLM post-training. I've published several CCF-A papers as first author, including LoRA-flow (ACL 2024), Delta-CoMe (NeurIPS 2024), and LongDPO (ACL 2025). Currently, I'm interning with the Qwen post-training team, where I'm involved in the post-training of Qwen3 (Qwen3 technical report).
See Google Scholar for more details.
Previously, I've interned at several companies, including ByteDance, Tencent's WeChat Group, and Alibaba's Qwen team.
