Atomic resolution scanning transmission electron microscopy (experimental)

In my PhD I am working on quantitative analysis of heterostructure interfaces with Scanning Transmission Electron Microscopy (STEM). I am particularly interested in a novel technique called momentum-resolved STEM. There, hundreds of diffraction patterns are recorded every second which allows us to map fundamental material properties at atomic resolution. The aim of my project is to overcome the computational challenge of handling a data stream of hundreds of GB per minute and to develop new quantitative methods that yield information on sample properties like thickness, orientation or element distribution.

GR Student Bio:

I started my PhD at Forschungszentrum Jülich in January 2019. Before that, I studied Physics at Rheinisch-Westfälische Technische Hochschule (RWTH) Aachen University where I earned both my Bachelor’s and Master’s degree. I specialized in theoretical condensed matter physics and finished my Master thesis at Forschungszentrum Jülich while working in computer physics and micromagnetics.
I am very happy to have found a project where I can work in all three pillars of modern physics, namely experimental, theoretical and simulation/computer physics. This naturally brings me into contact with many new techniques, people and challenges. When not iterating on my analysis tools I like playing piano, learning languages and cooking.
