Biography
Angelica V. Hagsand defended her doctoral dissertation in 2014 at the Department of Psychology, University of Gothenburg, on the topic of how alcohol affects witnesses' memory. After her PhD, Hagsand received a three-year postdoctoral grant from the Swedish Research Council, spending one year at the University of Gothenburg and two years abroad at the Department of Psychology, Florida International University, USA. She later returned to the University of Gothenburg, where she worked as the lead researcher on a project funded by the Bank of Sweden Tercentenary Foundation. In addition to this, Hagsand has been involved in several international collaborations on various projects, including with American colleagues who secured funding from the National Science Foundation in the U.S.
In 2022, Hagsand became Associate Professor and Senior Lecturer in psychology at the Department of Psychology, University of Gothenburg.
Current research
Hagsand's ongoing research is interdisciplinary and spans multiple fields, including cognitive psychology, addiction psychology, biological/neuropsychology, legal psychology, social psychology, and personality psychology. More specifically, the research aims to study:
- The acute effects of alcohol intoxication on the brain (especially cognition and memory) in witnesses, victims, and suspects
- The long-term effects of alcohol abuse/addiction on the brain and its consequences for witnesses, victims, and suspects
- The methods used by police and other legal practitioners when conducting interviews with intoxicated witnesses, victims, and suspects
The ongoing research involves numerous international collaborations, including in the United States, the United Kingdom, and Australia.
Hagsand is also an Associate Editor of the international scientific journal Applied Cognitive Psychology.
