I am a PhD student of the EPSRC Centre for Doctoral Training in Metamaterials (XM2) in Exeter. My research project is about enhancing nonlinear optics in 2D sytems.
Originally, I am from Germany and studied Physics in Jena (B.Sc. and M.Sc.). In my bachelor thesis, I worked on laser wakefield acceleration of electrons by focussing a petawatt laser pulse onto a gas cell. Before starting my master, I spend five months as an occupational trainee at the University of Sydney. I used liquid crystal on silicon devices for mode division multiplexing in multi-mode fibres. Back in Jena, I focussed my master physics studies on the fields of optics and photonics. Within my master thesis project, I investigated active spontaneous emission modulation by coupling emitters to all-dielectric-metasurfaces embedded in a liquid crystal cell.
