Undergraduate researcher at USTC, focusing on LLM Personalization.

About me

Hi, I’m Juntao You (尤俊韬). I am currently a Ph.D. student at the University of Science and Technology of China (USTC), where I also received my Bachelor’s degree in Artificial Intelligence. I am fortunate to be advised by Prof. Fuli Feng and mentored by Yang Zhang at the USTC Lab of Data Science. My research focuses on LLM Personalization — understanding and enhancing how large language models can capture and adapt to individual user preferences.

🔬 Research Interests

  • LLM Personalization — Aligning language models to individual user preferences
