He qualified as a specialist in internal medicine in 2001 and in gastroenterology and hepatology in 2002 and since 2002 he has been working as a consultant at Ålesund Hospital. He defended his PhD thesis on oesophageal biomechanics and pain in 2010. Working in the comprehensive area of gastroenterology, he has a special focus on research and clinical work in neurogastroenterology and motility. He has set up a clinical motility laboratory and facilitated the establishment of a patient education school on irritable bowel syndrome. After taking the lead in establishing a Clinical research unit and the Biobank1 facilities at Møre & Romsdal Hospital Trust, he is now heading this unit. At the moment nearly 50 project/studies in the comprehensive field of clinical medicine is ongoing at the clinical research unit HMR. Furthermore he is co-heading a national multicenter project on inflammatory bowel disease, “The BIOSTOP-study” (NCT03011268) in collaboration with the University of Oslo. He currently takes an active part in two clinical study started January 2021/autumn, i.e. on marine salmon oil in pulmonary disease and fish oli in patients with atopic dermatitis. He is a major partner in the national study on “Donor Versus Autologous Fecal Microbiota Transplantation for Irritable Bowel Syndrome” REFIT2 (NCT04691544). At Møre & Romsdal Hospital Trust, he takes a special interest in facilitation of research studies, as well as research education. Currently i.e. April 2023, he supervises/co-supervises 5 PhD students. November 2020 to January 2023, he was head of research and innovation at Møre & Romsdal Hospital trust. As of 2023 he is head of deptartment of Clinical studies Møre & Romsdal Hospital Trust, acts as primary investigators in about almost 15 clinical studies/research project, follow up his outpatient clinic and promotes clinical research within the Hospital trust. As of August 2023, he will be coordinating and teaching 3^rd/4^thyear medical students in Ålesund NTNU_Link.
