About me

I'm a licenced psychologist, licensed psychotherapist, reserach group leader, and associate professor in clinical psychology at the Department of Clinical Neuroscience, Karolinska Institutet.

Research description

Anxiety disorders, depression and stress disorders are highly prevalent, lead to severe suffering for the affected, and are associated with substantial societal costs. The research in my group is focused on treatment and assessment of these disorders, with emphasis on health anxiety, i.e. a chronic and debilitating fear of acquiring somatic disease. Central aims of the research are also to investigate how psychological treatment works when provided in regular clinical settings and how well treatments work when delivered as via the Internet. I was part of the founding team of the Internet Psychiatry Clinic (www.internetpsykiatri.se), which is one of the leading clinics in the field of Internet-based treatment.
