Biography

Hi! I am a PhD student of CE at University of Massachusetts Lowell, under the supervision of Prof. Hengyong Yu. My research focuses on inverse problems in medical imaging, with a particular emphasis on computed tomography (CT) reconstruction. Supported by NIH-NIBIB, my work aims to develop diffusion-based and flow-based generative models for improving image quality from incomplete measurements, including low-dose, sparse-view, and limited-angle CT.
Previously, I obtained my M.S. in EEE at Hong Kong Polytechnic University, supervised by Prof. Kenneth Lam. I also work closely with Prof. Kewen Xia at Hebei University of Technology.
Beyond research, I love photography (and sometimes share posts on RedNote), playing badminton, and getting outdoors activities such as fishing, skiing, and climbing.
