In this episode, Dr. David Huang tells the story of how optical coherence tomography (OCT) grew from a single research project in an MIT lab into a mainstream medical technology that saves the eyesight of millions and launched an entirely new field of innovation. He reflects on the teamwork and collaborators who shaped the breakthrough—and why working with people has been the highlight of his career. Dr. Huang also looks ahead, sharing what his team is developing now and how OCT’s next generation could transform early detection and treatment even further.
