I explore how humans trade off risk and reward, and how such trade-offs might differ across the many domains in which we make decisions.
More broadly, I'm interested in the cognitive mechanisms and the neural structures that support our decision-making abilities - whether they are part of choice itself or support it (e.g., sensing, judgment, reasoning, learning).
I am also interested in what makes a good choice (optimality/ rationality) and how closely people approximate optimal strategies.
To explore these topics, I use psychophysics and other behavioural methods, computational modelling, eye-tracking and neuroimaging.
Are perceptuo-motor decisions really more optimal than cognitive decisions?

Perceptuo-motor, cognitive, and description-based decision-making seem equally good.
