"My group is involved in modern subfields of accelerator physics, in particular the interaction between electrons in the storage ring and femtosecond laser pulses to produce ultrashort pulses in the extreme ultraviolet and terahertz range. We are developing electronic and optical techniques for beam diagnostics and machine learning methods to optimize accelerator parameters. For example, one new activity is Compton scattering of laser photons by electrons to precisely determine their energy and other parameters. We collaborate with other accelerator centers in several areas, e.g., further development of synchrotron radiation sources and free-electron lasers, temporal and spectral shaping of terahertz pulses, and control of beam parameters in electron and proton machines. A current future project is the design of an electron source for time-resolved electron diffraction."



![3D visualisation of human neuronal tissue reconstructed by multi-scale X-ray phase contrast tomography. Neuronal cell nuclei are shown in yellow for the granule neurons in the dentate gyrus region of the hippocampus. Blood vessels are shown in red. By changing the X-ray optical magnification in the multi-scale recordings, one can zoom into regions-of-interest (red ovals). In these scans the resolution is high enough to resolve sub-structures of the nucleus, associated with different DNA packing regimes.
