About me

Associate professor and senior clinical lecturer. Research group leader. Consultant in Psychiatry at Psykiatri Nordväst.

Research description

The main objective of my research group is to find brain biomarkers for psychiatric disorders, to enable new diagnostic tools and treatment approaches. The main focus is the assessment of neuroinflammation and brain neurotransmission in patients with early stage schizophrenia using Positron Emission Tomography (PET). I am the principal investigator of the Karolinska Schizophrenia Project, which is a large collaboration between key research groups at KI, as well as four different clinics in Stockholm County (Psykiatri Nordväst, PRIMA (Nordöst), Norra Stockholms Psykiatri, Södra Stockholms psykiatri). Ongoing PET projects also include precinical studies in rodents, as well as methodological developments i to improve reliability and sensitivity in clinical studies.
