Curricula Vitae
Erik van den Ban
Erik van den Ban (1956) studied mathematics at Utrecht University where he obtained his PhD in 1982. In the academic year 1982/1983 he was a member at the Institute for Advanced Study in Princeton. After having been post-doc at the Mathematical Centre (now CWI) in Amsterdam he became assistent professor in the Department of Mathematics of Utrecht University. He occupied short term visiting positions in Berkeley and in Copenhagen and in 1995 a four month visiting position at the Mittag-Leffler Institute in Djursholm, Sweden. In 2002 he was promoted to associate professor and in 2007 to professor in Lie theory.
Van den Ban's research area is analysis and representation theory for reductive Lie groups and symmetric spaces. He investigated the asymptotic behaviour of matrix coeffients, and the role of the principal series of representations in harmonic analysis on reductive symmetric spaces. In a long collaboration with Henrik Schlichtkrull from the University of Copenhagen he succeeded in obtaining Plancherel and Paley-Wiener theorems for such spaces.
Frans Clauwens
Frans Clauwens (1950) studied mathematics at the Katholieke Universiteit Nijmegen (now Radboud Universiteit), where he obtained his PhD in 1975 and became an assistant professor. His research interests include algebraic and differential topology, in particular surgery theory, algebraic K- theory and algebraic L-theory. He is researching the peculiarities of lambda-rings with a view to using these to provide methods for calculating K- and L- groups in the nonfinite cases.
Gunther Cornelissen
Gunther Cornelissen (1971) works on automorphic forms over global function fields, the theory of non-archimedean uniformization and its links with non-commutative geometry, deformation theory of group actions on curves and complexity questions about rational points.
He received his Ph.D. in 1997 from the University of Gent (Belgium) under the supervision of Jan Van Geel and Ernst-Ulrich Gekeler on a grant from the Belgian National Science Foundation, and then spent four years at the Max-Planck-Institute in Bonn (Germany), before accepting a position as lecturer-researcher at the University of Utrecht in 2001. In 2004-2009, he is the principal investigator of a VIDI-Innovational Research grant from the Dutch National Science Foundation. In 2007, he took up a Profile Chair in Mathematical Physics (interaction between mathematical physics and arithmetic geometry) at Utrecht University, initially funded by the GQT-cluster.
A description of research interest can be found here.
Robert Dijkgraaf
Robbert Dijkgraaf (1960) holds the chair of Mathematical Physics at the University of Amsterdam since 1992 (and is since 1998 Faculty Professor in the Faculty of Science). He studied theoretical physics and mathematics in Utrecht, where he obtained his PhD cum laude under supervision of Gerard 't Hooft in 1989. Subsequently he held a postdoctoral position at Princeton University and was a long-term member at the Institute for Advanced Study. He has been a visiting professor in Berkeley, MIT, IAS, among others. Dijkgraaf research group works in string theory, quantum gravity, and the interface of mathematics and particle physics. He manages the FOM programs "Mathematical Physics" and "String Theory and Quantum Gravity."
Dijkgraaf gave an invited lecture at the ICM in Berlin (1998) and was a plenary lecturer at the International Congress of Mathematical Physics (London, 2000) and the European Congress of Mathematics (Barcelona, 2000). Dijkgraaf is a member of the Royal Netherlands Academy of Arts and Sciences (KNAW) and the Koninklijke Hollandse Maatschappij van Wetenschappen. He was the recipient of the 2001 Physica Prize of the Dutch Physical Society. In 2003 he was awarded the Spinoza Prize, the highest scientific award in the Netherlands.
Dijkgraaf is editor of Nuclear Physics B, Journal of Differential Geometry, Journal of Geometry and Physics, Advances in Theoretical and Mathematical Physics, International Mathematical Research Notices, Journal of Mathematical Physics, Reviews of Mathematical Physics, Elsevier Mathematical Library, Academische Boekengids, and was an editor of Communications in Mathematical Physics from 1992 to 2002. Dijkgraaf was a director of the spring school at the ICTP Trieste (1992-1996) and has served on various international scientific committees among other for the Isaac Newton Institute for Mathematical Sciences in Cambridge, Max-Planck-Institut fur Mathematik in Bonn, Erwin Schroedinger Institut fur Mathematische Physik in Vienna, and the International Review of UK Mathematics.
Hans Duistermaat
J.J. (Hans) Duistermaat (1942) studied mathematics at Utrecht University from 1959-65 and obtained his PhD degree there in 1968. After a postdoctoral year 1969-70 in Lund (Sweden), where he learned Fourier integral operators from H�rmander, he went in 1971-74 to Nijmegen, where he became full professor in 1972. In 1974 he returned to Utrecht on the chair of professor Freudenthal, where he has stayed until now.
He became member of the KNAW (Royal Dutch Academy of Arts and Sciences) in 1982, and Academy Professor in 2004, which means that he is supposed to do research without being distracted by administrative duties until his retirement.
He has been `promotor' of 17 PhD students, of which 10 as the main thesis advior. Several of these were NWO projects, and one was research paid by Shell.
Duistermaat's current interests include classical mechanics, symplectic differential geometry, high-frequency asymptotics of solutions of linear partial differential equations, the differential geometric theory of arbitrarily nonlinear partial differential equations, and stochastically perturbed dynamical systems. Apart from 43 articles in refereed international journals, he has written 7 books, of which probably the introduction to Fourier integral operators is the most well known. His best known research is probably his article with Guillemin on spectra of elliptic operators and periodic bicharacteristics, his article with Heckman on the Duistermaat-Heckman formula, and his article with Gr�nbaum on the bispectral problem.
At the moment his main editing task is being co-ordinating editor of Indagationes Mathematicae, the mathematics journal of the KNAW.
Gerard van der Geer
Gerard van der Geer (1950) studied mathematics at the University of Leiden. He received his PhD from that university in 1977. Subsequently he worked at the Sonderforschungsbereich at Bonn University and then got a position at the University of Amsterdam, where he has been full professor in Algebra since 1987. He spent long visits at research institutes like MSRI at Berkeley and the Max-Planck-Institut at Bonn, and foreign universities like Harvard, the University of Tokyo and Kyoto University.
Van der Geer has been managing editor of Compositio Mathematica for more than ten years and is editor of Geometriae Dedicata and of the EMS Monograph series. He is member of the scientific committees of the Max-Planck-Institut fuer Mathematik in Bonn and the Research Institute in Oberwolfach. He has successfully supervised seven PhD theses (including those of C. Faber and G. Farkas) and is currently supervising another three. He was one of the initiators of the big NWO projects "Moduli" and "Algebraic curves and Riemann surfaces". He started the well-known series of Texel conferences.
Van der Geer has worked on Hilbert modular surfaces, on which he wrote the well-known volume "Hilbert Modular Surfaces" in the Ergebnisse series of Springer, on the Schottky problem, where he contributed with van Geemen a conjectural solution, on moduli of curves and abelian varieties, and on curves over finite fields. His current research deals with cohomology of local systems on moduli spaces and with moduli of Calabi-Yau varieties. He has published over 50 research papers in refereed journals.
Gert Heckman
Gert Heckman (1953) studied mathematics at the University of Leiden, where he obtained his PhD in 1980. After a period of 2 years as postdoc at MIT, he returned to Leiden as assistant professor until 1988, with a half year interruption as visiting associate professor at Universite Paris 7. From 1989 until now he has been at the University of Nijmegen, from 1999 on as professor of pure mathematics. He has trained 3 PhD students.
Heckman' s research interests include symplectic geometry and geometric quantization, algebraic geometric analysis (hypergeometric functions, differential Galois theory), and representation theory of reductive groups. About his joint work with Eric Opdam he was invited to give lectures at Seminair Bourbaki (1997) in Paris, and Current Developments in Mathematics (1996) at Harvard.

After a year of Mathematics at the University of Amsterdam, he was a guest-researcher in the group of Prof. dr. N. P. Landsman at the Korteweg-de Vries Institute for Mathematics. In 2005, van Suijlekom obtained his PhD-degree at the International School for Advanced Studies (SISSA) in Trieste, Italy, under supervision of Prof. L. Dabrowski and Prof. G. Landi.
From November 2005 until December 2006, van Suijlekom is a postdoc at the Max Planck Institute for Mathematics in Bonn, Germany. In January 2007, he will start as a postdoc at the IMAPP in Nijmegen, the Netherlands.
Van Suijlekom's field of research is noncommutative geometry; his work concentrates at its interaction with quantum group theory as well as its applications to quantum Yang-Mills gauge theories.
