I'm a cognitive scientist studying human communication in all its diversity. I’m particularly interested in gestures, metaphors, and conceptual systems. I ask how these vary across cultures, why we use them, and what they tell us about being human. Past projects have involved experiments in the lab; analyses of multimodal corpora and ethnographic databases; and fieldwork in Papua New Guinea.
