About Me

I am a Ph.D. student at The Hong Kong Polytechnic University, advised by Prof. Jing Qin. My research focuses on medical AI, medical imaging, brain-computer interfaces, and generative artificial intelligence for healthcare applications.

Before joining PolyU, I was a Research Assistant at SIAT, CAS, under the supervision of Prof. Zhanli Hu.

Prior to that, I received my M.S. in Biomedical Engineering from Imperial College London, advised by Prof. Mengxing Tang. I received my B.S. from the University of Nottingham.
