After receiving his PhD in 1987 he was an International Fogarty Fellow at the NIH, USA, and also spent a postdoctoral stay in Cambridge, UK. In 2008 he was appointed full professor at Uppsala University. At this time he had started to combine mechanistic cellular work with clinical studies in a childhood obesity cohort at the Uppsala University Children's Hospital, where he is also adjunct professor. His translational research addressing obesity and obesity-related complications in children with obesity and isolated human islets has focused on several aspects including insulin and glucagon secretion, circulating fatty acid levels and incretin GLP-1. The incretin was also the focus of a clinical trial led by him. In recent years he has started community-based preventive work addressing childhood health by initiating the intervention strategy Ending ChildHood obesity (ECHO) zone. He has published over 100 original articles and received several research awards.
