Soft matter is already ubiquitous in our daily life. New developments in medical technology, energy storage, and information technology also exploit soft materials characterized by complex, often nanoscale hierarchical structures. The scientific goal of this research training group is to harvest the potential of interfaces as agents to control the assembly process, pathways and the final properties of these materials. There is a need (in academia and industry) to better understand non-equilibrium processes, which we address through combining collaborative research and theoretical-experimental tandem projects, with structured training in a small and highly dedicated team.
