About

Hi! I am a Ph.D. student in Computer Science at the University of Georgia, advised by Dr. Fei Dou. Previously, I was a research assistant at the Hong Kong University of Science and Technology with Prof. Dit-Yan Yeung. I received my M.Sc. from University College London and B.Sc. from the University of Liverpool.

I build evidence-grounded and explainable AI for clinical diagnosis and health sensing: models that read physiological signals (ECG, PPG, BCG, BSG) and clinical records, acquire the evidence they need, and reason to a diagnosis that a clinician can audit.
