My research mainly focuses on higher cognitive functions, such as language, calculation, reasoning, and decision making. Using functional neuroimaging and computational modeling techniques, I examine both variability and commonality of these different cognitive domains in the human brain.

I am also interested in how learning and experience alter individual performance, as well as the neural implementation of such individual variability.
