About

I am an economist specialising in behavioural and experimental economics. My research focuses on decisions under risk and uncertainty in individual and social contexts, with applications to medical decision making. Central to this line of work is the description–experience framework: whether probabilities are described up front or learned through experience changes the choices people make, even when the odds are identical. My work has helped bring this framework, first developed in psychology, into economics (see this interview for an overview). A second strand asks how individual judgments pool into reliable collective assessments, including in matters of subjective taste (see this podcast for an informal take on that work). I am also interested in methodological challenges of preference elicitation, incentive design and model estimation, with the aim of building more accurate and more predictive models of economic behaviour. I pursue these questions through laboratory, online and field experiments.

Currently, I am an Assistant Professor in the Department of Economics at the University of Crete. Previously I was a postdoctoral researcher at the Technical University of Munich. I obtained my PhD in 2019 from the University of Nottingham and remain an external fellow of the Centre for Decision Research and Experimental Economics (CeDEx).
