Professor Vergnaud has made major contributions to the theory of generative grammar, both in the area of syntax and in phonology. His current research projects include work for GRECO Communication Parlee, a cooperative research projection speech recognition in France; a second project on the acquisition of phonology; and a third project, Outils pour le development d' interfaces en langage naturel. He is also involved with the new university program in cognitive science which centers on those aspects of language that are of interest to neurological and psychological theory and about computer science.
