He pursues a fundamental understanding of the basic objects of arithmetical algebraic geometry—motive, L-functions, Shimura varieties—and applies the methods of algebraic geometry to trigonometrical sums, linear differential equations and their monodromy, representations of finite groups, and quantization deformation. His research includes work on Hilbert’s twenty-first problem, Hodge theory, the relations between modular forms, Galois representations and L series, the theory of moduli, tannakian categories, and configurations of hyperplanes.</p> <p><em>Université Libre de Bruxelles, Ph.D. 1968; Université Paris-Sud 11, Ph.D. 1972; Fond National de la Recherche Scientifique, Belgium, Junior Scientist 1967–68; Institut des Hautes Études Scientifiques, Visiting Member 1968–70, Permanent Member 1970–84; Institute for Advanced Study, Member 1972–73 and 1977, Visitor 1981, Professor 1984–2007, Professor Emeritus 2008–; Académie des Sciences, Institut de France, Foreign Member; Académie Royale de Belgique, Foreign Member; Accademia dei Lincei, Foreign Member; American Academy of Arts and Sciences, Foreign Member; American Philosophical Society, Member; London Mathematical Society, Honorary Member; Moscow Mathematical Society, Honorary Member; National Academy of Sciences, Foreign Member; Norwegian Academy of Science and Letters, Foreign Member; Royal Swedish Academy of Sciences, Foreign Member; Académie Royale de Belgique, François Deruyts Prize 1974; Académie des Sciences, Institut de France, Henri Poincaré Medal 1974; Fond National de la Recherche Scientifique, Belgium, A.
