Work that uses high-level mathematics and/or invents new mathematical tools to solve applied problems from engineering, science, and technology is particularly appropriate. The value of the work will be measured by the quality of the mathematics and its impact on the application. Each prize may be given either for a single notable achievement or for a collection of such achievements.

2015 Recipient:

George Em Karniadakis

Brown University

__Citation__: The 2015 Ralph E. Kleinman Prize is awarded to George Em Karniadakis for his many outstanding contributions to Applied Mathematics in a broad range of areas, including computational fluid dynamics, spectral methods and stochastic modeling.

**George Em Karniadakis**is Charles Pitts Robinson and John Palmer Barstow Professor of Applied Mathematics at Brown University. He has been a Research Scientist at MIT’s Department of Ocean/Mechanical Engineering since 2000. He received his S.M. (1984) and Ph.D. (1987) from MIT. He was appointed Lecturer in the Department of Mechanical Engineering at MIT in 1987 and subsequently joined the Center for Turbulence Research at Stanford/NASA Ames Research Center. In 1988, he joined the faculty of Princeton University as Assistant Professor in the Department of Mechanical and Aerospace Engineering and as Associate Faculty in the Program of Applied and Computational Mathematics (PACM). Karniadakis moved to Brown University as Associate Professor of Applied Mathematics in the Center for Fluid Mechanics in 1994, becoming full professor in 1996 and attaining his current title in 2013.

**George Pólya Prize for Mathematical Exposition**

The George Pólya Prize for Mathematical Exposition, established in 2013, is awarded every two years to an outstanding expositor of the mathematical sciences. The prize may be awarded for a specific work or for the cumulative impact of multiple expository works that communicate mathematics effectively. The nature of the work may range from popular accounts of mathematics and mathematical discovery to pedagogy to systematic organization of mathematical knowledge. This is the first award of the prize.

2015 Recipient:

Gerhard Wanner

University of Geneva, Switzerland

__Citation__: The 2015 George Pólya Prize for Mathematical Exposition is awarded to Gerhard Wanner primarily for the five very readable books that he has co-authored. They display deep mathematics, presented with elegance, enthusiasm, wit, scholarship, and much history. These books have uniquely delineated numerical ODEs (especially stiff equations) and geometric integration and created an historical perspective for the teaching and understanding of analysis and geometry.

**Gerhard Wanner **began his long-lasting career in Geneva first as an invited professor in 1973, following this up as an associate professor 1974-1976 and becoming a full professor at the University of Geneva in 1976. He studied mathematics at the University of Innsbruck 1961-1965, concluding with a doctorate in 1965. He then held an assistant position at the University of Innsbruck 1965-1968, was an assistant professor at the University of Wisconsin in Madison in 1968, and continued as a lecturer at the University of Innsbruck 1968-1973. Wanner was repeatedly president of the Section of Mathematics at the University of Geneva. He was subsequently secretary, vice-president and president of the Swiss Mathematical Society in the years 1994-1999. He received the Peter Henrici Prize jointly with Ernst Hairer in 2003.

The George Pólya Prize was established in 1969 as a quadrennial prize in combinatorics. It was extended in scope in 1992, following a generous bequest from the estate of Stella V. Pólya. It was extended to be given biennially alternately in two categories: (1) for a notable application of combinatorial theory; (2) for a notable contribution in another field of mathematics of interest to George Pólya (e.g., approximation theory, complex analysis, number theory, orthogonal polynomials, or probability theory.).

In 2013, the George Pólya Prize for Mathematical Exposition was created to bring greater emphasis to Pólya’s legacy of communicating mathematics effectively. At the same time, the biennial prize was divided into two quadrennial prizes, the George Pólya Prize in Combinatorics (first award in 2016) and the George Pólya Prize in Mathematics (first award in 2014).

Recipients of the Pólya Prize for Mathematical Exposition receive an engraved medal and a cash award of $10,000.

2015 Recipients:

Patrick E. Farrell, University of Oxford

Simon W. Funke,Simula Research Laboratory

David A. Ham,Imperial College London

Marie E. Rognes,Simula Research Laboratory

__Citation__: For the development of **dolfin-adjoint**, a package which automatically derives and solves adjoint and tangent linear equations from high-level mathematical specifications of finite element discretizations of partial differential equations.

The need for adjoints of partial differential equations (PDEs) pervades science and engineering. Adjoints enable the study of the sensitivity and stability of physical systems, and the optimization of designs subject to constraints. While deriving the adjoint model associated with a linear stationary forward model is straightforward, the derivation and implementation of adjoint models for nonlinear or time-dependent models is notoriously difficult. **dolphin-adjoint** solves this problem by automatically analyzing and exploiting the high-level mathematical structure inherent in infinite element methods. It is implemented on top of the FEniCS Project for finite element discretizations.

**Patrick E. Farrell** received his Ph.D. from Imperial College London, and is currently an EPSRC Research Fellow in the Mathematical Institute at the University Oxford. His research interests include linear and nonlinear solvers for forward and adjoint PDEs adaptive discretizations, and optimization problems constrained by partial differential equations. His most recent research addresses the question of computing distinct solutions of nonlinear PDEs.

**Simon W. Funke** received his Ph.D. from the Imperial College London, and currently works for the Biomedical Computing Department at Simula Research Laboratory in Norway. His research interests include adjoint models, optimization constrained by partial differential equations and applications to biomedicine and marine renewable energy.

**David A. Ham** received his doctorate from Delft University of Technology and is currently a NERC Research Fellow at Imperial College London. His current research focuses on the automated generation of finite element models, and particularly on abstracting the mathematical structure of numerical discretizations and simulation domains to most effectively exploit current and emerging parallel hardware.

**Marie E. Rognes** received her Ph.D. from the University of Oslo and is currently a Senior Research Scientist and Head of the Biomedical Computing Department at Simula Research Laboratory in Norway. Her research interests revolve around structure-preserving discretizations of PDEs such as mixed finite element methods, automated code generation and error control, and applications in biomedical modeling and simulation.

### James H. Wilkinson Prize for Numerical Software

Starting in 2019, by agreement among ANL, NPL, NAG, and SIAM, the prize will be administered by SIAM. The James H. Wilkinson Prize for Numerical Software will join the James H. Wilkinson Prize in Numerical Analysis and Scientific Computing as a major SIAM prize. The prize fund was established by generous donations in 2015 from ANL, NPL, and NAG. The prize will be awarded every four years at meetings of the SIAM Conference on CS&E. The next award of the prize will be given in 2019. A $3,000 cash award and a suitable engraved plaque will be presented to the recipients.

### SIGEST Authors

SIGEST contains digested versions of selected papers from SIAM’s research journals. Each journal’s Editorial Board, in turn, nominates work for SIGEST. The final choice of papers is made by the Editor-in-Chief and Section Editors of SIAM Review (SIREV) on the basis of exceptional quality and potential significance to the entire SIAM community. Authors of these papers achieve a wider readership than could be reached by a specialized research journal alone. This section provides a rare opportunity for readers from all segments of the SIAM community to keep up with important research from outside their areas of specialization.

SIAM recognizes the authors of the papers published in SIREV’s SIGEST section in 2014.SIREV 56(1)
