PhD candidate, cognitive science, Lund University

In my PhD project - "The malleability of political attitudes" - I have been exploring the cognitive mechanisms behind attitude change, and how much people know about their own political beliefs. The research builds on findings showing that peoples' deep-seated political beliefs are highly flexible and easily influenced by the situation and observations about their own behavior. I have used experimental methods inspired by the choice blindness paradigm to explore how our minds adapt and update itself in response to new information.

Besides this research, I explore novel and innovative techniques to study public opinion.

Here is a short video clip from a documentary showing my research in action:
