My lab studies (a) the relationship between working memory and cognitive control: how is the contents of working memory controlled, and how it is used to control behavior, and (b) group-level cognition: characterizing cognitive processes at the group level, rather than only at the individual level. For example, what is the working memory capacity of a group, do executive functions exist at the group level, and what are their characteristics (e.g., limitations, decision making processes, and relationship to individual-level processes).
