SIAM outstanding paper prize for Dr. A. Shapeev

Dr Alexander Shapeev, a former Post-Doc at EPFL in the Chair of Computational Mathematics and Numerical Analysis (ANMC) has been awarded one of the 2013 SIAM Outstanding Paper Prizes for his work done at EPFL. The selected paper: "Consistent Energy-Based Atomistic/ Continuum Coupling for Two-Body Potential in One and Two Dimensions" has appeared in SIAM Multiscale Modeling and Simulation Vol. 9, No 3 (2011), pp. 905--932.

The paper addresses the question of coupling of atomistic and continuum descriptions of equilibria of solids. These coupling algorithms have been increasingly popular among engineers and materials scientists since 90s, but theoretically they were not well-understood in more than one dimension. The paper proposes the first such algorithm in two dimensions whose accuracy is systematically improvable. More importantly, by introducing important tools, the paper led to extension of the existing numerical analysis theory of atomistic-to-continuum coupling to many dimensions.

The "Society for Industrial and Applied Mathematics" (SIAM) is a big community of more than 14000 applied mathematicians, engineers and computer scientists. SIAM has been founded in 1952 to foster strong interactions between mathematics and other scientific and technological communities through membership activities, publication of journals and books, conferences and prizes.

The SIAM Outstanding Paper Prizes, first awarded in 1999, are granted each year to three outstanding papers published in SIAM journals during the three years prior to the year of the award. Papers are selected for their originality, bringing a fresh look at an existing field or opening up new areas of applied mathematics.

The prize will be presented at the 2013 SIAM Annual Meeting (AN13), to be held July 8-12, 2013, at the Town and Country Resort & Convention Center in San Diego, California.
