I have 15 years of experience from genetic studies of both common and rare disorders. My research interests centers around trying to understand the genetic underpinnings of a wide range of disorders such as rare highly heritable genetic disorders, diabetes and related traits and ADHD.

I lead the genetics studies in three reserch consortia: KG Jebsen center for Neuropsychiatric Disorders, KG Jebsen Center for Diabetes Research and the Genomics Group at the Dept of Clinical Science and Senter for Medical Genetics and Molecular Medicine.
