The group is dedicated to studies on structure and functionality of complex interfaces. At present research topics focus on biolubrication, responsive solid-liquid interfaces and biomimetic systems and their interactions with cellular components as probed by surface sensitive neutron and x-ray scattering as well as infrared spectroscopy. The group is responsible for the neutron reflectometer V6 and the new TOF neutron reflectometer BioRef (V18), the latter in cooperation with the Ruprecht-Karls-Universität Heidelberg (Prof. (apl.) R. Dahint, Prof. M. Grunze). The group keeps a strong interactive research profile with its short and long term cooperation partners. Within the colloidal physics user laboratory the group provides specialised on-site preparation techniques (Layer-by-layer deposition, spin coating, Langmuir-Blodgett and Langmuir-Schäfer deposition) and further off neutron-beamline characterisation.
