Boaz Keysar
Principal InvestigatorBoaz Keysar is the William Benton Professor in Psychology at the University of Chicago. He studies how people use language, how they make decisions, and how the two are related. He investigates how people use their knowledge of others to communicate and to interpret language, and how being in the mode of a foreign language systematically affects the way they make decisions.
He was a fellow at the Center for Advanced Study in the Behavioral Sciences at Stanford, a Guggenheim Fellow, and has received the best paper award from the Psychonomics society.
