Personal profile
Short presentation
Office hours: Monday-thursday 8:00-17:00
I joined the Department of Psychology at the University of Copenhagen as an Assistant Professor in January 2023. Prior to that, I studied Psychology at the University of Southern Denmark (2013-2018), took a PhD in Psychology at the University of Copenhagen (2018-2021), and worked as a postdoc at both Aarhus University and the University of Copenhagen (2021-2022).
My main research interests include the areas of Behavioral Economics, Personality, Judgment and Decision-Making, Behavioral Ethics, and Social Data Science. I am particularly interested in the economics of pro- and antisociality, and especially how pro- and antisocial personality traits shape people’s economic decisions.
