On Jan. 1, 2012, Dr. Petr Plechac joined the Editorial Board of SIAM Journal on Numerical Analysis (SINUM). The SINUM belongs to the leading journals in the field of numerical analysis and computations. The journal publishes research articles on the development and analysis of numerical methods. Topics include the rigorous study of convergence of algorithms, their accuracy, their stability, and their computational complexity. Also included are results in mathematical analysis that contribute to algorithm analysis, and computational results that demonstrate algorithm behavior and applicability.

On Dec 1, 2011 Dr. Petr Plechac was reappointed as Associate Editor of SIAM Multiscale Modeling and Simulation. Centered around multiscale phenomena, Multiscale Modeling and Simulation (MMS) is an interdisciplinary journal focusing on the fundamental modeling and computational principles underlying various multiscale methods.
