I am a Senior Adjunct Researcher at the University of Basel and a researcher at the Universitary Psychiatric Clinics in Basel, Switzerland. My main research interests are in Clinical and Social Psychology. I study the health care system for patients with psychosis and decision making with a focus on diversity as well as truth judgments and misinformation.
