Chenhang Li is Co-Founder, CFO, and COO at Lumius Imaging, a Y Combinator-backed medtech startup building fast, smart, and accessible 3D ultrasound devices to replace outdated 2D imaging in clinical settings.

Chenhang is a Ph.D. candidate at Duke University specializing in wearable electronics, mechano-acoustic wave sensing, ultrasound and photoacoustic imaging, and multiphysics modeling of bioelectronics.

Chenhang is passionate about combining cutting-edge wearable technology with data-driven medical imaging strategies to make healthcare more accessible for underserved populations.

Lumius was selected for Y Combinator's Spring 2026 batch (YC P26) and is co-founded alongside Duke Ph.D. alumni Luca Menozzi (CTO) and Tri Vu, with early focus on vascular access procedures such as central line placement.

Lumius targets a market of 500 million ultrasound scans performed annually, with a long-term vision of building a universal 3D ultrasound platform for clinical and consumer applications including blood clot detection, tumor diagnosis, and biopsy guidance.
