Jiawen Tao 陶佳文

I am a master's student at Peking University, advised by Prof. Tong Yang. I grew up in Changzhou, Jiangsu, and received my B.S. in Information and Computing Science from Peking University in 2025, with a dual degree in Economics from the National School of Development.

My research focuses on large language models, especially data synthesis for pre-/mid-training and LLM evaluation. I am currently interning at Tencent Hunyuan and previously interned at Moonshot AI (Kimi) and Tongdeng Asset Management (quantitative research).

Outside of research, I play Go and the guitar, and I am usually up for badminton, table tennis, or billiards with friends. I also love traveling — a few days somewhere new is still the surest way for me to reset.

Feel free to reach out if you would like to discuss research or explore potential collaborations.
