Ulf W. Gedde holds the professor chair of Polymeric Materials at the KTH Royal Institute of Technology, Stockholm, Sweden. Professor Gedde's research interests are plastics, polymers, and their properties, polymer physics, crystalline polymers–molecular structure, crystallization kinetics, morphology and properties, thermotropic liquid crystalline polymers, polymers in power-electronics, the long-term performance of polymers, relaxation processes in polymers, polymer fracture, transport properties, polymeric outdoor insulating materials and polymer nanocomposites. Gedde is the author of 300 peer-reviewed scientific papers and one textbook on Polymer Physics (1995) and 5 patents. He has graduated 44 Ph.D students and was one of the scientific sources for the development of bimodal polyethylene materials (Borstar). Gedde has been Editor of European Polymer Journal and is currently Editor of Polymer Testing. Gedde is member offour journal editorial boards. His teaching activities extends over 40 years and span over a wide range of fields across polymer science.
