Tri Vu

Tri Vu is the co-founder and CEO of Lumius, a Durham, North Carolina medical imaging startup building fast, smart, accessible 3D ultrasound - what the team calls a 3D camera for the body. A Duke-trained biomedical engineer with a doctorate in ultrasound and photoacoustic imaging and more than 1,900 research citations, Vu left an academic track to turn a decade of imaging research into a device clinicians actually want to pick up. Lumius went through Y Combinator's Spring 2026 batch and is starting with vascular access, where roughly half of first attempts fail.
