Research Interests: Risky and intertemporal choice; decisions from experience; reinforcement learning; behavioural science; computational modelling; gambling; estimation. The main focus of my research is on judgment and decision making with an emphasis on the computational modelling of the underlying psychological and cognitive processes. Specifically, I am interested in how people make choices under risk and uncertainty in various basic and applied domains, the role of learning and memory processes, and the combination of different sources of information when people make judgments and decisions. To provide insights into the mechanisms of human behaviour, my research utilises a mixture of laboratory experiments, quantitative techniques, and computational cognitive models. Contact Details
