My background is variable and interdisciplinary. I received a BA in Greek Philology from Aristotle University of Thessaloniki and an MA in Linguistics from Utrecht University. In 2017 I received a Ph.D in Social Psychology from the Université libre de Bruxelles.

I currently hold a joint postdoctoral researcher position at the Oxford Internet Institute and the Oxford-Emirates Data Science Lab.

My main research interests lie broadly in the area of Social Psychology and Social Cognition, and specifically focus on how available information affects people’s beliefs and behaviour.

My Ph.D thesis was an experimental assessment of the human tendency to believe information we encounter (the truth-bias), combining a social psychological and a

linguistic approach. This video may give you an idea of the work I conducted in the context of my thesis [] and also allows you to test your own gullibility should you wish to try!

My current research focuses on the social, cognitive and evolutionary factors that affect the truth-bias, as well as on its socio-political consequences, especially in the digital era.

I’m also interested in misinformation transmission and Conspiracy Beliefs, both from a cognitive and from a socio-political perspective.

Before coming to Oxford, I was a research associate at the University of Cambridge, where I worked in a project investigating the effects of sustainability information on investor decision-making.
