About me

I am a licensed psychologist and researcher in child- and adolescent
psychiatry. I am affiliated to Center of Neurodevelopmental Disorders at
Karolinska Institutet (KIND) and involved in the project Roots of Autism and
ADHD Twin Study in Sweden (RATSS). In RATSS the causes of autism spectrum
condition and ADHD are explored with the help of monozygotic and dizygotic
(identical and nonidentical) twin pairs with and without neurodevelopmental
disorders.
