Laurent Prévot is a professor in Language Sciences at Aix Marseille Université and the director of Laboratoire Parole et Langage. He is also a junior member of the Institut Universitaire de France (IUF). His specialties are linguistics (in particular semantic and pragmatic questions) and Natural Language Processing. He obtained his PhD (2004) in Computer Science from Toulouse 3 University and worked as post-doc in linguistic and interdisciplinary labs in Italy (Laboratory for Applied Ontology, Trento), France (Syntax and Semantics Research Team CLLE-ERSS, Toulouse 2) and Taiwan (Institute of Linguistics, Academia Sinica). His recent projects are dealing in particular with conversational feedback, interpersonal dynamics in conversation as well as neural bases of conversation. At the methodological level, he tends to use NLP and speech processing techniques on conversational corpora and exploit the resulting material in collaboration with colleagues from various disciplines (linguistics, machine learning, neurosience, dialogue systems). Recently he has devoted his research time in developping and applying data-intensive and / or experimental approaches to conversational language.
