I am Chenxiao Fan, a first-year Master’s student in the Lab of Data Science (LDS) at the University of Science and Technology of China (USTC), advised by Prof. Xiangnan He and Prof. Fuli Feng.

I received my Bachelor’s degree in Electronic Information Engineering from the School of Information Science and Technology, USTC, in 2025. Currently, I am pursuing my Master’s degree in Intelligent Science and Technology at the School of Artificial Intelligence and Data Science, USTC.

My research interests include large language models (LLMs), recommender systems, and reinforcement learning. Outside of research, I enjoy traveling, exploring local cuisine, and listening to Mandarin pop music. I hope to continue growing as a researcher while maintaining a balanced and fulfilling life.
