Lukas Rosellini

Field Service Engineer

About

I’m a Biomedical Engineer passionate about solving complex problems with elegant, practical solutions, and I’ve been doing that across startups, global medtech companies, and award-winning academic projects. At Bayer, I support and analyze the performance of complex radiology imaging systems in clinical environments, applying diagnostics, troubleshooting, and engineering insights to improve reliability, usability, and system performance. Previously, at Johnson & Johnson MedTech, I contributed to next-generation bone surface reconstruction tools, writing algorithms that convert CT data into highly accurate 3D models for orthopedic surgical planning. At Boston Scientific, I gained hands-on experience with design, prototyping, and testing for interventional spine devices, learning injection molding processes, feasibility testing, and supplier specifications. But I don’t just tinker—I innovate. I designed a bedside sepsis diagnostic device that won Best Product Design and Presentation, blending acoustophoretic technology with Raman spectroscopy. I’ve led teams through rapid prototyping, built adjustable eyeglasses for patients with shifting prescriptions, and developed a vibrating vest to help children with COVID-related respiratory issues in underserved communities. What drives me is curiosity—a hunger to understand systems, explore new approaches, and improve outcomes. Whether it’s designing bedside diagnostic tools, mentoring fellow engineers, or collaborating across disciplines, I bring a builder’s mindset and a teammate’s heart to every project. If you’re looking for someone with technical depth, creative energy, and a relentless drive to make things better, let’s connect.
