Christian Karl works in the group polymer and composite materials at SINTEF Industri and has a background with a doctorate in tribology and wetting of polymer composites/polymer analysis from the University of Hanover (Germany). He studied polymer and colloid chemistry with a focus on polymer physics and water-soluble polymers at the University of Bayreuth (Germany). Christian has worked in various fields within polymer chemistry and physics and physical chemistry (interfaces of polymers, wetting phenomena, mechanical and tribological properties of polymeric nanomaterials, elastomers, polymeric fiber composites, thermoplastics, biopolymers, analytical chemistry, material characterization, compounding of polymers, rheology) as project and group leader/postdoctoral fellow.
