About me

I am a clinically active paediatrician and paediatric endocrinologist and work in the department of paediatric endocrinology at Karolinska University Hospital in Solna, and at the National Childhood Obesity Centre located in Liljeholmen. I am heading the regional working group on childhood obesity in Region Stockholm.

I have a keen interest in global health, especially maternal and child health. I have worked in several countries, the lastest was Ethiopia with the London School of Hygiene and Tropical Medicine (LSHTM). I am connected with the Department of Women's and Children's Health (KBH) here at Karolinska Institutet.

I am the deputy Editor-in-Chief of the scientific journal Acta Paediatrica.

I also lead the working group that should give directions for obesity care for children and adolescents in the Stockholm region, "Regional arbetsgrupp barnobesitas (RAGBO)."
