About

Sheng-Chieh (Leon) Chiu

I am a Postdoctoral Researcher at the Digital Medicine and Smart Healthcare Research Center, NYCU, working on sovereign AI and digital twin technologies for healthcare. My research journey began with a deep personal motivation — caring for family members affected by neurodegenerative diseases — and has since grown into a commitment to building trustworthy clinical AI at the intersection of neuroimaging, deep learning, and surgical computer vision.
