Chairman and Chief Executive Officer, AREP Group Graduate of the Ecole Polytechnique, Graduate engineer of Ecole Nationale des Ponts et Chaussées Architect DPLG In 1977, Jean-Marie Duthilleul joined the team at the Secretariat for New Towns, which were springing up at that time. Concurrently, he taught for over ten years at the Ponts et Chaussées school of engineering, convinced that it was necessary to breathe new life into the profession of design engineer. In 1980, along with a number of architects and town planners working in public sector establishments or for local authorities, he founded a not-for-profit body called "Architecture, Town Planning and the Public Sector" to debate the profession of designer in public sector organisations. In 1982, he joined the team charged with preparing a Universal Exhibition in Paris and with organising the construction of major state programmes in Paris. In 1986, attracted by his experience as an architect and engineer, the top management of SNCF asked him to reorganise the architecture department. At that time he laid the theoretical basis for designing contemporary mainline railway stations, which he saw as spaces requiring simultaneous urban and architectural approaches. In 1997, after winning the international competition to design the new mainline station in Seoul, he set up AREP with Etienne Tricaud and became its Chairman. He expanded his activity outside the area of transport and movement amenities in the heart of the city and began to explore fields as varied at public buildings, town planning and large-scale urban territories. More recently, he has contributed to the studies for developing the Greater Paris of the future.
