Kardefelt-Winther holds a post-doctoral research position at the Department of Clinical Neuroscience and Centre for Psychiatry Research at Karolinska Institutet in Sweden. His work at Karolinska Institutet takes an interdisciplinary approach to excessive use of technology and its health outcomes by integrating social science and medical research perspectives. At present he coordinates a project at the Stockholm Centre for Dependency Disorders which investigates co-morbidity between substance addiction and internet addiction in a clinical population of substance abusers.
Based on his previous work for the European Commission funded EU Kids Online project he is also involved in research and policymaking efforts regarding children’s internet use, online safety and child rights.
