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 polymer chemistry and physics (polymer interfaces, surface characterization, analytical chemistry, mechanical and tribological properties of polymeric nanomaterials, rubber materials, polymeric fiber composites, thermoplastics, biopolymers, compounding of polymers, rheology) as project and group leader/postdoctoral fellow.
