Natural and Artificial Photonic Structures and Devices
Johannes is a Marie-Curie COFUND research fellow at INL and works in the Natural and Artificial Photonic Structures and Devices Group (Department of Nanophotonics). He studies photonic structures in the silicate cell wall of diatoms, i.e., microscopic algae that populate all aquatic environments on Earth. Using advanced microscopes and micro-scatterometric techniques, the project investigates light modulation by biological photonic structures and their potential implications for the light harvesting of diatoms. Inspired by these mechanisms, optical materials will be fabricated with the aim of improving light harvesting technologies for advanced photonic devices.
Johannes studied biology with focus on plant sciences at the University of Giessen (DE). He received his PhD degree from the University of Copenhagen (DK) in 2017 for his work on biophotonics of diatoms. Since then, Johannes worked as a postdoctoral fellow at the Remote Sensing and benthic Ecology Group at the University of Nantes (FR), before he joined INL in September 2018.
