CS Staff Contribute to SIAM

The annual SIAM Conference on Computational Science and Engineering is being held this week, February 25–March 1, in Boston, MA. The SIAM CS&E conference seeks to enable in-depth technical discussions on a wide variety of major computational efforts on large problems in science and engineering, foster the interdisciplinary culture required to meet these large-scale challenges, and promote the training of the next generation of computational scientists.
