Professor for Theoretical Physics
My field of expertise at the University of Düsseldorf is the physics of colloids, which are finely distributed particles or droplets in a medium. These can be fat droplets in water, as in milk, or solid color particles in ink. I am particularly fascinated by phenomena such as freezing, melting and glass formation. I am also enthusiastically involved in teaching. In this way, I can pass on what I learned at the TU Dortmund. Until 1986, I completed a lightning study program of just under seven semesters there. This was possible mainly because I was able to learn theory and experiment at the same time in the integrated course and thus save time. I also did my doctorate in Dortmund, then went to Munich and Lyon for my habilitation and finally returned close to home.



![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.
