🎓
Top SchoolKoji Yamada is a seasoned optical and medical-device engineering leader with over two decades of experience translating semiconductor and compound‑semiconductor optics into commercial medical products. As General Manager at FiberTech, he leads development of ultra‑thin endoscopes (0.4–2 mm) and associated lenses and image‑transmission fibers, driving extreme miniaturization for ophthalmology, cardiology and minimally invasive biotech. He previously led R&D and commercialization of an ophthalmic endoscope with integrated laser therapy (approved and launched in 2022) and held senior optical design roles at NEC and Renesas. Koji blends deep hands‑on expertise in laser diodes, lens systems and fiber optics with strategic new‑business development and cross‑divisional program leadership.

Colleagues know him for pushing the limits of what can be made thinner, lighter and clinically practical.
