Brief Research Overview:
My research evaluates the robustness of cognitive constructs of risk taking, and the
way they interact with contextual factors (e.g., payoff valence, ways of acquiring information, social exposure) to affect decisions.
The evaluation includes testing the predictive value of quantitative behavioral models that aim to capture these interactions.
Current Research Topics:
Adaptive decision-making and decisions from experience
Constructs of risk-taking and risk perception
Loss aversion as a context effect
Social influences and impacts of others' behavior
Choice prediction competitions
