The focus of Jukka Seppälä’s research has evolved from the polymerisation and copolymerisation of olefins to polymer compounds and subsequently to bioactive and biodegradable compounds. He has shown extraordinary innovation in developing new polymerisation methods and searched for applications for the new materials developed in his laboratory. Professor Seppälä’s research is deeply interdisciplinary and highly productive. He has turned his focus to materials that have application in the targeted delivery of medical drugs and in surgical procedures, for instance as bioactive tissue growth matrices. During his term of Academy Professor, his main research interests will lie in the manufacture of new polymers with biomedical applications and in the use of new 3D techniques in the manufacture of bioactive matrices.
