The Predictive Science Academic Alliance Program (PSAAP) centers focus on the emerging field of predictive science—the application of verified and validated computational simulations to predict the behavior of complex systems where routine experiments are not feasible. The centers focus on unclassified applications of interest to NNSA and its three national laboratories: LLNL, LANL, and SNL. The PSAAP centers develop not only the science and engineering models and software for their large-scale simulations but also methods associated with the emerging disciplines of verification and validation (V&V) and uncertainty quantification. The goal of these emerging disciplines is to enable scientists to make precise statements about the degree of confidence they have in their simulation-based predictions. For additional information, see the NNSA Press release announcing PSAAP II

Recognizing the scarcity of U.S. citizens enrolling for advanced degrees in fields crucial to the success of ASC, two complementary Graduate Fellowship programs, both administered by the Krell Institute, are supported.
