👨‍💻 About Me

I am now a third-year PhD student at Beijing Jiaotong University, advised by Prof. Yufeng Chen, Prof. Kaiyu Huang, and Prof. Jinan Xu. Before that, I started my master’s degree in 2021 and transferred to the doctoral program in 2023. I am now interning at WeChat AI, Tencent.

My research interests include LLM Post Training; Multilingual large language models; Multilingual analysis and interpretability; Knowledge transfer and distillation.
