The Society for Industrial and Applied Mathematics (SIAM) has numerous activity groups in various areas of mathematics, ranging from algebraic geometry to uncertainty quantification.
Julie Bessac, a computational statistician in Argonne’s MCS division, will serve as program director of SIAM Activity Group on the Mathematics of Planet Earth (SIAG/MPE). The group provides a forum for studying the life-supporting capacity of the Earth and the impact of human activities. Bessac has made significant contributions in the field of wind modeling, environmental extremes and climate risk analysis. As SIAG/MPE director, she will be responsible for the scientific programs of all SIAG activities, including the biennial SIAM Conference on Mathematics of Planet Earth, SIAG activities at the SIAM Annual Meeting, and SIAG-sponsored meetings, conferences, and workshops.
Emil Constantinescu, a computational mathematician in Argonne’s MCS division, will serve as secretary for the SIAM Activity Group on Uncertainty Quantification (SIAG/UQ). The group seeks to promote the development of theory and methods to describe the origin and propagation of sources of error and uncertainty in analysis. Constantinescu has developed strategies and analyzed the effect of uncertain ambient conditions of energy systems and Earth system modeling. As SIAM/UQ secretary, he will be responsible for maintaining a record of SIAG activities, producing and distributing SIAG newsletters and ensuring the accuracy of the SIAG on the SIAM website.
Each of the newly elected officers will serve a two-year term beginning January 2023. For more information about the various activity groups, see the SIAM/SIAG website.
