I am interested in discovering plausible mechanisms by which the brain can infer and represent the relationship between causes and effects. To do so, I use computational models that are inspired by some characteristics of the nervous system to simulate existing data on learning phenomena and generate novel, testable, predictions. I use behavioural and psychophysiological measures to study how people detect statistical regularities in their environment and how this influences the way they allocate their attention. I am also interested in studying brain disorders that involve learning and attention abnormalities.
