He has held the position of Programme Manager for the Nordic Nuclear Safety Research's (NKS) emergency preparedness and radioecology programme and  has chaired the OSPAR Commission's Radioactive Substances Committee since 2010. He currently also chairs an IAEA coordinated research project with the aim of providing an updated overview of levels, trends and impacts of radionuclides in the global marine environment.
