In 1986 he moved to IRIS (Institut de Recherche et d'Information Socio-Économique) at the Université de Paris-IX Dauphine, where he spent the latter part of his teaching career. During this time he had begun to move away from sociology as a discipline (particularly in its "classical" form), and, after ceasing to teach full-time, he rarely identified himself with any particular discipline, although he remained linked to academia. During the 1980s and 1990s his books had gained a wide audience, and in his last years he became, to an extent, an intellectual celebrity, being published often in the French- and English-speaking popular press. He nonetheless continued supporting the Institut de Recherche sur l'Innovation Sociale at the Centre National de la Recherche Scientifique and was "Satrap" at the Collège de Pataphysique. Baudrillard taught at the European Graduate School in Saas-Fee, Switzerland, and collaborated at the Canadian theory, culture, and technology review "Ctheory", where he was abundantly cited. He also participated in the "International Journal of Baudrillard Studies" from its inception in 2004 until his death. In 1999–2000, his photographs were exhibited at the Maison européenne de la photographie in Paris. In 2004, Baudrillard attended the major conference on his work, "Baudrillard and the Arts", at the Center for Art and Media Karlsruhe in Karlsruhe, Germany.
