1974, he lived with the Embera-Wounaan tribe in Panama. He has been married since 1975 to Jémia Jean, who is Moroccan, and has three daughters (one by his first marriage with Rosalie Piquemal). Since the 1990s they have divided their residence between Albuquerque, Mauritius, and Nice. In 1983 Le Clézio wrote a doctoral thesis on colonial Mexican history for the University of Perpignan, on the conquest of the Purépecha people who inhabit the present-day state of Michoacán. It was serialized in a French magazine and published in Spanish in 1985. Le Clézio has taught at a number of universities around the world. A frequent visitor to South Korea, he taught French language and literature at Ewha Womans University in Seoul during the 2007 academic year. In November 2013, Le Clézio joined Nanjing University in China as a professor. Literary career Le Clézio began writing at the age of seven; his first work was a book about the sea. He achieved success at the age of 23, when his first novel, Le Procès-Verbal (The Interrogation), was the Prix Renaudot and was shortlisted for the Prix Goncourt. Since then he has published more than thirty-six books, including short stories, novels, essays, two translations on the subject of Native American mythology, and several children's books. From 1963 to 1975, Le Clézio explored themes such as insanity, language, nature, and writing. He devoted himself to formal experimentation in the wake of such contemporaries as Georges Perec or Michel Butor. His persona was that of an innovator and a rebel, for which he was praised by Michel Foucault and Gilles Deleuze. During the late 1970s, Le Clézio's style changed drastically; he abandoned experimentation, and the mood of his novels became less tormented as he used themes like childhood, adolescence, and traveling, which attracted a broader audience. In 1980, Le Clézio was the first winner of the newly created Grand Prix Paul Morand, awarded by the Académie Française, for his novel Désert. In 1994, a survey conducted by the French literary magazine Lire showed that 13 percent of the readers considered him to be the greatest living French-language writer. Nobel Prize The Nobel Prize in Literature for 2008 went to Le Clézio for works characterized by the Swedish Academy as being "poetic adventure and sensual ecstasy" and for being focused on the environment, especially the desert. The Swedish Academy, in announcing the award, called Le Clézio
