About Me

I am Huatong Song (宋华彤), a first-year Master’s student at the Gaoling School of Artificial Intelligence (GSAI), Renmin University of China (RUC), supervised by Prof. Xin Zhao. I am expected to graduate in June 2028.

I enrolled in GSAI at RUC in September 2021 and received a Bachelor of Engineering degree in Artificial Intelligence in July 2025. In parallel, I also obtained a Bachelor’s degree in Finance from the Gaoli Institute of RUC. I have a broad interest in Natural Language Processing, Large Language Model and Agent.
