The Marian Group at UCLA
Our group focuses on understanding materials evolution under extreme conditions using multiscale computational modeling. Formulating theoretical models of materials behavior under a variety of far-from-equilibrium conditions, e.g. shock-loading, very fast deformation rates, high dose and dose rate irradiation, ultrafast heating, etc., requires a deep understanding of a wide range of physical processes. We develop efficient computational techniques to implement these materials models, taking advantage of large-scale parallel computing capabilities. At every possible scale, our simulations are benchmarked against and validated with experimental data to build confidence in the models. Specific areas of interest are microstructural evolution and mechanical property degradation in fusion materials, simulations of plastic deformation in alloys, simulations of thermodynamics and phase transformations in functional materials, strength in nanostructured crystals, and simulations of irradiation damage in a variety of situations. The overarching goal of our work is to influence materials synthesis and design by understanding their internal evolution under prescribed conditions.

Jaime is the PI on a four-year multi-institutional proposal bringing together materials scientists, computational scientists, and applied mathematicians for developing simulation codes of reactor materials degradation in realistic fusion oeration conditions. The project involves investigators from five different universities (UCLA, Stony Brook, Wisconsin, Miami, and Villanova) and four National Laboratories (ORNL, PNNL, INL, and SNL).

The Marian group has received two new grants from DOE to study materials degradation processes in neutron irradiation environments.
The first one is part of the Office of Nuclear Energy's NEUP program, where we will study irradiation-assisted stress corrison cracking in austenitic steels. UCLA is the lead institution in a collaboration with UC Berkeley, EPRI, and Westinghouse Corporation.
The second one is part of the INFUSE program to foster public-private partnerships to advance fusion energy. The Marian group at UCLA (lead) and a group at the University of Tennessee-Knoxville will assist Commonwealth Fusion Systems (CFS) to develop structural materials for CFS' tokamak concepts.
