My main research interests include human learning and decision making. Particular topics are how people learn to make better decisions from their experience, how they generalise their experience to novel situations, and when and why people stray from well-known alternatives to try new ones. I approach these topics with a combination of behavioural experiments and mathematical modelling. I am also interested in advancing statistical methods, and develop tools and techniques in this area, for instance mixture and hidden Markov modeling, and optimal adaptive experimental design.
