Laurent Praly graduated from École Nationale Supérieure des Mines de Paris in 1976. After working in industry for three years, in 1980 he joined the Centre Automatique et Systèmes at École des Mines de Paris. From July 1984 to June 1985, he spent a sabbatical year as a visiting assistant professor in the Department of Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. Since 1985 he has continued at the Centre Automatique et Systèmes where he served as director for two years. In 1993, he spent a quarter at the Institute for Mathematics and its Applications at the University of Minnesota where he was an invited researcher. His main interest is in feedback stabilization of controlled dynamical systems under various aspects -- linear and nonlinear, dynamic, output, under constraints, with parametric or dynamic uncertainty --. On these topics he is contributing both on the theoretical aspect with many academic publications and the practical aspect with applications in power systems, mechanical systems, aerodynamical and space vehicles.
