I studied business administration at the Berlin School of Economics and Law. I then went on to study psychology, first at Martin-Luther University Halle and then at the University of Göttingen, where I received my PhD in 2010. Prior to joining QUB in April 2022, I was a senior researcher at the University of Göttingen.

I am an experimental social psychologist whose research also draws from cognitive psychology and IO-psychology. I am interested in how social contexts influence the way we make judgments and decisions. My basic research focuses on quantitative judgments in interacting groups (how wise are interacting groups?) and in judge-advisor systems (why are we so resistant to advice?). The applied part of my work is concerned with escalation of commitment in financial decision-making and, in particular, how decision-makers use information such as expert advice in escalation contexts.
