Research Fellow
Centre for Brain-Computing Research (CBCR), Nanyang Technological University

I am a research fellow at NTU, working at the intersection of neuroscience, AI, and brain-computer interfaces. My research focuses on understanding the spatiotemporal neural dynamics of human cognition using multimodal neuroimaging (EEG, fMRI, MEG, PET), and translating these insights into non-invasive speech decoding BCIs.

I received my BS in Engineering Physics from Tsinghua University, and my PhD in medical imaging from the University of Chinese Academy of Sciences (IHEP), mentored by Prof. Baoci Shan. I currently work with Prof. Cuntai Guan, Prof. Victoria Leong, and Prof. Balazs Gulyas.
