Background and activities
In the framework of a Feodor Lynen Fellowship from the Alexander von Humboldt foundation I am currently working at NTNU. I am working with Dennis Meier to engineer the conductivity of domain walls in single- and polycrystalline hexagonal manganite model materials, which is an important requirement for future all-domain wall devices.
I received my B.Sc. and MSC degree from the University of Erlangen-Nurnberg in the group of Prof. Greil. During my studies I was working as a research scholar in the group of Prof. Messing at Pennsylvania State and Prof. Gauckler at ETH. I received my PhD in 2018 in the group of Prof. Rödel at TU Darmstadt working together with Dr. Koruza on functional polycrystalline ceramic materials. In the frame of my PhD thesis I investigated the mechanism of polarization reversal in polycrystalline ferroelectric/ferroelastic ceramics. We illustrated the mechanism as a well-defined sequence of switching events physically originating from an interplay between local electric and mechanical fields.
