Development of reactive polymers is my profession. They are e.g. applied as adhesives, potting resins, matrix resins for fibre reinforced plastics or 3D printing. The development is usually carried out for industrial customers. Typically the desired materials do not exist already and special properties are required. This is often to improve productivity or sustainability. In addition to my job as deputy director of Fraunhofer IFAM and head of the department "Adhesives and Polymer Chemistry" I am Professor for Polymer Chemistry at University of Bremen. Family, rowing, running, cycling, hiking are the things taking my leisure time.
