Research interests

My doctoral thesis studied how alcohol affect witness memory of a crime and we investigated this in a lab at Sahlgrenska hospital. After my PhD, I was a post doc researcher at the Department of Psychology, Florida International University, USA. Together with the American research team we continued to more closely examine the effects of alcohol on witness memory using new methods. Beyond this, I have also been involved in research projects on alcohol-dependence.

Hence, my research is interdisciplinary and stretches between cognitive psychology, legal psychology, social psychology, biological psychology, addiction psychology and personality psychology. More specific, my research interest concerns both the acute effects of alcohol on cognition and behavior (i.e. witness memory of a crime, how alcohol affect suspects during interrogation), and the long-term consequences of alcohol-dependence. I am also interested in police studies.
