Federal Grant Award Summary

The University of Utah received a $558,188 Project Grant award from the National Science Foundation's Office of Integrative Activities under the Geosciences Program (CFDA 47.050), effective January 15, 2026, through December 31, 2028. This collaborative research initiative develops interpretable artificial intelligence (AI) models to understand the dynamical behavior of dense granular media in geosciences, specifically particle-laden flows such as avalanches, volcanic flows, and river sediments. The project integrates laboratory experiments, advanced numerical simulations, and transparent AI methodologies to create an elasto-viscoplastic continuum rheology for dense granular suspensions under varying stress conditions, addressing fundamental questions regarding force chain representation and fluid-particle interactions in geophysical flows.

The award supports the delivery of enhanced forecasting capabilities for natural hazards and improved engineering models of Earth systems, alongside significant educational and outreach components. Deliverables include publicly accessible AI tools, YouTube tutorials, and quarterly seminars designed to disseminate advances in AI for geosciences. The project employs a vertically integrated training model wherein postdoctoral researchers mentor graduate and undergraduate students in a collaborative research environment, thereby preparing a new generation of researchers with expertise in both scientific computing and Earth science. These research outputs and educational products directly advance the National Science Foundation's mission to strengthen the national scientific enterprise through fundamental knowledge expansion in Earth system sciences.
