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.
Van den Ban is editor of Transactions and Memoirs of the American Mathematical Society.
Gil Cavalcanti (1977) did his D.Phil. in Oxford University under the supervision of Nigel Hitchin and finished his degree in 2004. After that he held an EPSRC scholarship to work in Oxford as Hitchin's post-doctoral research assistant from 2005 to 2008. At the same time he was also a Junior Research Fellow in Jesus College. At the end of his post-doc, in 2007, Cavalcanti was awarded a Veni grant from NWO and a Marie Curie IEF grant from the European Research Council to work in the mathematics department in Utrecht, from 2008. In 2009 Cavalcanti was appointed as assistant professor in Utrecht.
Cavalcanti's area of research is generalized complex geometry and nearby areas of complex and symplectic geometry. He is currently working on questions concerning generalized complex structures on 4-manifolds, including a possible Lefschetz fibration structure for those as well as differential invariants which might be associated to such manifolds. Some of his long term collaborators are Marco Gualtieri (University of Toronto) and Henrique Bursztyn (IMPA).
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 (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.
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.
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 Hörmander, 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 Grünbaum 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 (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 (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.
Wilberd van der Kallen studied mathematics (and undergraduate physics) at the Rijksuniversiteit Utrecht. There he also obtained his PhD in 1973 under professor Springer. He is a member of the Utrecht Mathematics Department since 1969. He has worked for some time in algebraic K-theory. His current interest involves representation theory of algebraic groups. He has repeatedly visited Northwestern University (Evanston, Illinois, USA) and the Tata Institute for Fundamental Research (Mumbay, India).
The main research interest of van der Kallen is in representations of reductive algebraic groups like the group of n by n matrices of determinant one. An important tool in his work has been the method of Frobenius splittings from algebraic geometry. Van der Kallen has conjectured connections between invariant theory, a topic from the nineteenth century, and the homological algebra of the represesentations of reductive algebraic groups.

Eduard Looijenga (1948) obtained his Masters's degree in mathematics at the University of Amsterdam in 1971. From 1971 till 1973 he stayed as a junior fellow at the Institut des Hautes Études Scientifiques and in 1974 he took his doctoral degree at the University of Amsterdam. After holding a postdoc position at the University of Liverpool (1974-75), he was appointed Professor at the University of Nijmegen (1975). From 1987 till 1990 he was at the University of Amsterdam and in 1991 he took his current position at the University of Utrecht. He held visiting positions at Yale (1980), U. of North Carolina at Chapel Hill (1985), Columbia U. (1987), U. of Michigan at Ann Arbor (1990), U. of Utah (1991).
His research started in singularity theory, but migrated via Torelli problems (often related to rational surfaces and K3 surfaces) to locally symmetric varieties, then to mapping class groups and moduli spaces of curves, while his recent work is concerned with automorphic forms with poles along Heegner divisors and (jointly with Heckman and Couwenberg) generalizations of Lauricella functions.
Looijenga was an invited speaker at the ICM in 1978 and at the ECM in 1992. He was on the selection panel for Algebraic Geometry of the ICM in 1994, the Prize Committee of the ECM in 2000 and the Scientific Committee of the ECM in 2004. Since 1995 he is an ordinary member of the Royal Netherlands Academy of Arts and Sciences (KNAW). He is currently editor of Comp. Math., Michigan Math. J. and the J. of the Eur. Math. Soc..
Izak (Ieke) Moerdijk (1958) studied mathematics, philosophy and general linguistics at the University of Amsterdam. He received his PhD in Mathematics from the same institution in 1985, with the distinction Cum Laude. Subsequently he worked at the University of Chicago and at the University of Cambridge, before joining the Mathematics Department of the University of Utrecht in 1988, where he has been a Professor of Topology since 1996. Moerdijk was awarded a Huygens Fellowship from NWO in 1986 and a PIONIER grant, again from NWO, in 1995. Moerdijk held visiting positions in Cambridge (St John's College), Montreal (McGill University), Sydney (University) and Aarhus, among others. He was an invited speaker at the ECM 2000.
At Utrecht, Moerdijk has successfully supervised nine PhD theses, and is supervising another three at present.
Moerdijk's current research interests include algebraic and differential topology (operads, Lie groupoids, ...), and applications of topological structures in mathematical logic. He is the coauthor of several well-known books, including "Sheaves in Logic and Geometry" with S. Mac Lane (Springer-Verlag, 1992, 1994), and "Introduction to Foliations and Lie Groupoids" with J. Mrcun (Cambridge UP, 2003). He has published over 60 research papers in refereed journals. Together with C. Berger, he recently provided a solution to the problem of the existence of homotopy model structures for operads and their algebras.
Moerdijk is editor of The Annals of Pure and Applied Logic, of The Journal of Pure and Applied Algebra, and of Theory and Applications of Categories, and is a member of the Advisory Board of North-Holland Mathematical Library.
Ben Moonen studied mathematics at the University of Utrecht. He has been a Visiting Fellow at Harvard during the Spring of 1994. After receiving his PhD at the University of Utrecht in 1995, he held postdoctoral positions in Muenster and Princeton, after which he obtained a KNAW Fellowship. In 2001 he moved to the University of Amsterdam, where he is now UHD. His main research interests lie in the domain of Arithmetic Algebraic Geometry, and include Abelian Varieties, Shimura Varieties, and Moduli theory. He is managing editor of Compositio Mathematica.
Michael Mueger (1965) studied physics at the Technical University Darmstadt, where he obtained his diploma in 1992. He received his PhD in mathematical physics from Hamburg University in 1997. From then until 2004 he worked as a postdoc in the mathematics departments of the universities Tor Vergata and La Sapienza (Rome), of Universite Louis Pasteur (Strasbourg), where he obtained his habilitation diriger des recherches in 2002, at the School of Mathematics of Tel Aviv University, at MSRI (Berkeley) and at the Korteweg-de Vries Institute (UvA). Since 2004 he works at Radboud University (Nijmegen), now as universitair docent in Analysis and Mathematical Physics.
Mueger's research currently focuses on category theory, low dimensional topology, quantum groups, operator algebras and rigorous quantum field theory (axiomatic, constructive, conformal, topological).
Dietrich Notbohm (1955) studied Mathematics at the Universität Göttingen, where he received his PhD in 1988 and his Habilitation in 1992. Subsequently Notbohm worked in Göttingen and Bielefeld, held visiting professorships in Münster (University) and Chicago (Northwestern University) and spend two years at the Max Planck Institute for Mathematics in Bonn, before he was appointed as lecturer at the University of Leicester. He was promoted to reader (2003) and to professor in mathematics (2005). In 2007, he moved to Amsterdam where he became professor of geometry at the Vrije Universiteit. Notbohm's research is in the area of algebraic topology and homotopy theory. In particular, he is interested in toric topology with connections to differential topology, commutative algebra, homological algebra and combinatorics, and in the homotopy theory of classifying.
Eric M. Opdam (1960) studied mathematics at the University of Leiden. He received his PhD in Mathematics in 1988, also at the University of Leiden. He worked at the University of Utrecht and at the Massachusetts Institute of Technology before accepting a permanent position at the University of Leiden in 1989. He stayed in Leiden until 1999 when he was appointed as professor in Mathematics at the University of Amsterdam.
Opdam has held positions as a visiting professor at several occasions in Ann Arbor (MI, USA), Paris, Marseille and Kyoto. He was invited speaker at the EMC in 2000 and at the ICM in 2006. In 2000 he was awarded a prestigious Pionier grant from NWO. He has successfully supervised 2 PhD students, and he is currently training three more. In 2001 he was honorary promotor when Ian Macdonald was granted an honorary doctorate degree at the University of Amsterdam.
Opdam's research interests include representation theory, Lie groups and algebraic groups, Hecke algebras, integrable systems, special functions, and operator algebras. In his work he has paid special attention to applications of techniques across traditional borders. This has led to active contacts with researchers in various disciplines, ranging from algebraic combinatorics to Langlands philosophy.
I started out in 1989 as a first-year student at the Department of Mathematics and Mechanics of Moscow State University. After emigrating to the United States I transferred to New York University which I finished in May 1993 with a B.A. in Mathematics (Summa Cum Laude). In August of the same year I began my graduate studies at the University of California at Berkeley under the supervision of Alan Weinstein, and completed my Ph. D. in May 1999. Since then I've worked at Penn State University, Utrecht University, IHES and MPIM. I am currently working at Utrecht and Nijmegen Universities as part of Ieke Moerdijk's research group. I live in Amsterdam.
Dirk Siersma (1943) studied mathematics and meteorology at the University of Amsterdam. After a teaching position at a secondary school he returned to this university , where he received a PhD in 1974. His supervisor was Nicolaas H. Kuiper. He became associate professor in Utrecht in 1976 and full professor in 1980.
Siersma's active research interest is singularity theory and applications. His principal work includes classification of singularities, geometry and topology of non-isolated singularities, behaviour of singularities at infinity and more recently the study of the conflict set of the distance function. He was one of the founding members of the Dutch Singularity School. He has approximately 30 refereed research papers and supervised 11 PhD students.
Siersma has many East-European contacts: he has been coordinator of three consecutive INTAS programs with the former Soviet union and two NWO-programs with Russia. Moreover he has been main organizor of the Singularity Semester at the Newton Institute in Cambridge (Fall 2000) and (co)organizor of many international scientific meetings in his field, e.g. in the framework of the European Singularity Network. Recently he was invited guest at IHES (2 months), Banach Center (1 month) and the University of Lille (1 month).
Siersma was the first scientific director of the Mathematical Research Institute (MRI) in The Netherlands and the initiator of its scheme of international Master Classes.
I received my Ph.D. in theoretical physics in 2005 from the University of Essen, Germany. Then I spent four years as a postdoc in the math. department in Hamburg in the group of Christoph Schweigert. After a few months at the Hausdorff Institute for Mathematics in Bonn, I started a postdoc position in Utrecht at the end of 2009, in the group of Ieke Moerdijk.
My research is motivated from structural questions in mathematical physics and tends to involve tools from higher category theory.
(1979) studied mathematics at the Universiteit van Amsterdam. From 2002 till
2006 he was a PhD-student at the UvA, under the supervision of Eric Opdam. In
2007 he obtained his PhD and held short-term positions at the UvA and at the
Hausdorff Institut für Mathematik in Bonn. In september 2007 he moved to
Göttingen, where worked as a post-doc for four years. In june 2011 he received
his Habilitation from the Universität Göttingen.
Since the autumn of 2011 he is a tenure-track UD at the Radboud Universiteit Nijmegen.
research interest is in representation theory with a geometric flavour.
Recurring themes in his work are affine Hecke algebras, reductive p-adic groups,
and noncommutative algebraic geometry.
mathematics, Solleveld is an international master in chess. With his rating
2500, he ranks among the 25 best chess players of the Netherlands.
Joseph Steenbrink (1947) studied mathematics at the University of Nijmegen, where he got his degree in 1969. He received his PhD at the University of Amsterdam in 1974, where Frans Oort was his supervisor. Subsequently he spent a year at the IHES at Bures sur Yvette, invited by Pierre Deligne. He was supported by an NWO stipend. He became assistant professor at the University of Amsterdam and full professor at Leiden University in 1978. Since 1988 he has the chair in geometry at the University of Nijmegen. He supervised nine PhD students, several of whom (Van Straten, Stevens, de Jong) now are full professor. His main research interest is algebraic geometry, where he has developed tools in mixed Hodge theory and applied these to singularity theory. He was one of the leaders of the successful NWO-projects in Singularity Theory and Arithmetic Algebraic Geometry. He was invited speaker at many international events, notably at the ICM 1990 in Kyoto. He has been Managing Editor of Compositio Mathematica from 1982 till 1993, and is a member of the Advisory Boards of North-Holland Mathematical Library and Epsilon Uitgaven. He was dean of the Faculty of Mathematics and Informatics during six years, and scientific director of the Mathematical Research Institute. His current research interests are: geometry of moduli spaces and of certain special threefolds. He published 50 research papers in refereed journals.
Jan Stienstra's research interests:
Relations between the theory of motives and string theory. This includes, in concreto, research on toric geometry/GKZ hypergeometric systems/mirror symmetry, Picard-Fuchs equations/crystalline cohomology/large complex structure limit, Mahler measure/L-functions/melting crystals/dimer models.
Walter D. van Suijlekom studied Theoretical Physics at the University of Amsterdam from 1996 to 2001, and wrote his master's thesis under supervision of drs. G.G.A. Bauerle. 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.
