Silk for global health: Fiorenzo Omenetto. When we #StandWithScience for World Health Day, we stand with the optics researchers whose work enables groundbreaking applications for global health. By using silk as a material platform for advanced technology with uses in photonics, Omenetto's research has included topics covering room-temperature vaccines and food preservation and coral-reef safe reflecting powders for sunscreen; relying on technology from the planet, for the planet. As the Frank C. Doble Professor of Engineering in the Biomedical Engineering Department at tuftsuniversity, his research examines the convergence of technology, biologically inspired materials, and the natural sciences.
