Hello, I am Tingchen Fu (ไป˜ๅปท็› in Chinese), a 2nd-year master student in Gaoling School of Artificial Intelligence, Renmin University of China as an NLP researcher and a fanatic believer on AGI, advised by Xueliang Zhao and Rui Yan. I occasionally have short excursions to the industry world. Currently I am an intern at Tencent AI Lab, mentored by Dr. Lemao Liu and work in close colleboration with Dr. Deng Cai. I am actively seeking a PhD position in NLP starting at Fall 2025. If you are interested in my research, please feel free to contact.

I am genelly interested in machine learning, language technology, and their intersection, with a special emphasis on understanding and unleashing the full potential of Large Language Models. Specifically, I am currently interested in the following topics:

  • the alignment of large langauge model.
  • Data/Compute efficient language model training.
  • Understanding and mitigating the limitations of LLM like social bias, privacy leakage, and hallucination.
