Joachim Mayer

Prof. Joachim Mayer is the Head of the Central Facility for Electron Microscopy (GFE) at RWTH Aachen University and director of the Ernst-Ruska Centrum at Forschungszentrum Jülich. His research focuses on electron spectroscopy, analytical electron microscopy, and materials science. He leads interdisciplinary projects in energy storage materials, corrosion science, and advanced microstructural analysis.

His academic roles include directing state-of-the-art microscopy facilities and collaborating on international initiatives. Research interests span nanostructured materials, phase change materials, and defect engineering in alloys. Key contributions include studies on high-nickel cathode degradation, magnesium alloy microstructure refinement, and rolling contact fatigue mechanisms in bearing steels.

Recent work emphasizes correlative microscopy techniques, laser-annealed battery materials, and memristor-based neuromorphic systems. He has authored/co-authored over 200 peer-reviewed articles and holds editorial roles in microscopy journals. His lab supports research across RWTH departments and industry partnerships.
