"The research group deals with soft matter theory and biological physics. We study statistical physics, mechanics and hydrodynamics of soft and biological matter using analytical and numerical methods. In the soft matter field, the main interests are polymer physics, rheology of elastic materials such as capsules or shells, active self-propelled systems, and micro-floats. We are also actively developing new Monte Carlo simulation techniques (event-chain Monte Carlo) and new applications of machine learning in soft matter physics. In biological physics, cytoskeletal filaments (actin and microtubules) are the main topic. They convert chemical energy (ATP or GTP) during their polymerization to generate forces and motion at the cellular level. We study the physics of single filaments to bundles and networks of many filaments, and from equilibrium fluctuation to chemical drive by polymerization or molecular motors."



![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.
