Short presentation
In my research I apply neutron scattering methods to current challenges in material science. The goal is to relate macroscopic emergence to the structure and dynamics on molecular length scales. The focus is on soft mater, in particular complex liquids and their viscoelastic properties, as well as on magnetic and energy materials. In order to enable new research directions I am driving neutron instrument and method developments.
