Barbara Fox received her PhD in Linguistics from UCLA in 1984. Her research explores the mutual shaping relationship between grammar and usage, especially within face-to-face interaction. Her work reveals the importance of action and interaction to grammatical choice, and highlights the role of the body in constructing utterances. It also calls for an extraordinarily dynamic, and embodied, model of grammar. During her career at CU, Dr. Fox taught courses in semantics, pragmatics, morpho-syntax, Conversation Analysis, and Interactional Linguistics.
