Professor Govind Menon is receives NSF Career Award, July 2008 Professor Govind Menon receives an NSF Career Award in support of his work in the area of scaling and self-similarity in nonlinear science-education and research. His research is to bring empirical scaling laws into rigorous mathematical analysis as they affect complex nonlinear problems, and to analyze seemingly unrelated problems within a unified framework that merges mathematical methods from partial differential equations, dynamical systems, and probability theory. Joined to this research initiative, is an educational mission to develop undergraduate curricula that emphasize the extraction of simple quantitative answers from complex models. Undergraduate seminars and research collaboration will be designed to increase the grasp of a unified framework between the mathematical utility of scaling analysis in the areas of biology, physical chemistry and geosciences to the fundamental understanding of the microscopic origin of universal scaling laws.

David Gottlieb, Elected to National Academy of Sciences, 2007 David Gottlieb, Professor of Applied Mathematics at Brown University, has been elected to the National Academy of Sciences (NAS), one of the highest honors accorded to a scientist or engineer. Professor Gottlieb, who studies numerical analysis and methods for solving partial differential equations, is one of 72 new members and 18 foreign associates elected this year in recognition of their distinguished and continuing achievements in original research. His research involves constructing and applying high-order accuracy methods for the numerical solutions of partial differential equations. Professor Gottlieb chaired the Department of Applied Mathematics at Tel Aviv University before coming to Brown, where he has supervised almost 20 Ph.D. students and built a world-renowned research group studying numerical analysis and scientific computing.
Chi-Wang Shu, SIAM/ACM Prize in Computational Science and Engineering, 2007 Dr. Chi-Wang Shu, Professor Applied Mathematics, received the SIAM/ACM Prize in Computational Science and Engineering. He was awarded this prize, “for the development of numerical methods that have had a great impact on scientific computing, including TVD temporal discretization, ENO and WENO finite difference schemes, discontinuous Galerkin methods, and spectral methods." Shu initialized the development of a class of nonlinearly stable high order time discretization, termed TVD (total variation diminishing) time discretization, suitable for convection dominated partial differential equations. Shu is one of the original designers of the nonlinearly stable ENO (essentially non-oscillatory) and WENO (weighted ENO) finite difference and finite volume schemes, which are widely used to solve problems with strong shocks and can maintain uniformly high order accuracy. Shu is also one of the original developers of the RKDG (Runge-Kutta discontinuous Galerkin) finite element method, which are widely used to solve convection dominated partial differential equations.

David Mumford, 2007 AMS Leroy P. Steele Prize for Mathematical Exposition Presented annually by the American Mathematical Society, the Steele Prize is one of the highest distinctions in mathematics. The prize was awarded to Professor David Mumford on Saturday, January 6, 2007, at the Joint Mathematics Meetings in New Orleans, Louisiana. The prize citation honors Mumford for "his beautiful expository accounts of a host of aspects of algebraic geometry". Among the works mentioned in the prize citation is: The Red Book of Varieties and Schemes (Springer, 1988). In his response upon receiving the prize, Mumford recalled that some of his drawings from The Red Book were included in a collection called Five Centuries of French Mathematics. This seemed fitting, he noted: "After all, it was the French who started impressionist painting and isn't this just an impressionist scheme for rendering geometry?" The prize citation states that,"the classical theory is beautifully intertwined with the modern theory, in a way which sharply illuminates both." Press Release from the AMS, January 8, 2007.
