Christian Liebscher has held the professorship for Advanced Transmission Electron Microscopy at Ruhr University Bochum since April 2024. The newly established professorship is not only part of the Research Centre Future Energy Materials and Systems, but is based at the Faculty of Physics and Astronomy. Liebscher previously conducted research at the University of California, Berkeley, and has been a research group leader at the Max Planck Institute for Iron Research (MPIE) in Düsseldorf since 2015. Liebscher's professorship will play a central role within the RC FEMS in linking the functional properties of energy materials with their structural and atomic composition. This fundamental understanding is seen as a prerequisite for developing and customising new types of materials.
