About Me

Xufeng Duan

I am a PhD candidate in the Language Processing Lab at the Department of Linguistics, The Chinese University of Hong Kong (ranked among the top 50 in the QS rankings). I am seeking a RAP/AP position in 2025.

My research focuses on large language models (LLMs) and language production. I use behavioral, EEG, and fMRI data, along with computational methods, to explore the mechanisms of the language system. Additionally, I am trained and licensed in TMS for research purposes in Hong Kong and have completed an internship as a language therapist/researcher specializing in aphasia at the Third Affiliated Hospital of Sun Yat-sen University.
