HELLO! I'M johannes.
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.
Johannes Goessling is a plant biologist with strong interest in biological photonic structures, which are widespread in plants and other phototrophic organisms. During his early career, Johannes studied photosynthesis from different perspectives, including light harvesting and photoprotection, reciprocity of carbon and nitrogen cycles and photorespiration. He received his Ph.D. degree for his work on biophotonics of diatoms from the University of Copenhagen (DK) in 2017. Since then, Johannes worked as a postdoctoral fellow at the University of Nantes (FR), and joined INL recently to implement the COSiNUS project in the Natural and Artificial Photonic Structures and Devices Group led by Martin Lopez-Garcia (Department of Nanophotonics).
The Cofund project
The COSiNUS project is an interdisciplinary approach to investigate biological photonic structures in diatoms at the interface of biophysics, photobiological research and biomimetics. Diatoms, i.e. photosynthetic organisms in the plankton and benthos of marine, freshwater and many terrestrial habitats, are completely enclosed by cell walls made of silicic acid, named the frustule. The frustule is perforated with miniscule pores arranged in arrays of highly ordered periodicity that interfere with sunlight, thus potentially affecting quantum efficiencies of diatom photosynthesis. By reconstruction of the complex three-dimensional organization with state of the art nano-fabrication techniques, this project will yield artificial materials with special optical properties inspired by the photonic structures of diatom frustules. The project aims at better understanding the relationship between biological photonic structures and solar energy utilisation in nature, while inspiring innovation and design of more efficient light energy-harvesting technologies.
