Multiscale Hybrid Modeling of Materials
GROUP LEADER: Javier Dominguez, Ph.D., DSc
Dr. Javier Dominguez received his Ph.D. in Computational and Applied Physics with Summa Cum Laude honors from the National University of Mexico. He continued his academic training at Stony Brook University, where he worked on plasma–material interaction modeling in collaboration with the Princeton Plasma Physics Laboratory. He later joined the Max Planck Institute for Plasma Physics in Germany as an Alexander von Humboldt Research Fellow, also supported by a Siemens Foundation scholarship. In recognition of his innovative contributions to nuclear materials research, he received the IAEA International Challenge Prize for developing a machine learning tool dedicated to the analysis of radiation-induced defects. In 2023, he obtained his habilitation in Physics and was appointed Institute Professor at NCBJ.
At NOMATEN CoE, Dr. Dominguez leads a research group dedicated to developing multiscale numerical models to understand the response of advanced materials, including high-entropy alloys, under extreme environments such as high temperature and irradiation. His team collaborates with CEA (France) and other major European institutions, integrating modeling and experiments to support the design of materials for fusion, fission, and industrial applications. He has published over 60 peer-reviewed journal articles, is actively engaged in European scientific networks, and contributes to the international community through editorial, reviewer, and leadership roles.

DESCRIPTION OF THE SCIENTIFIC ACTIVITIES
The group’s scientific activities are dedicated to advancing multiscale modelling and artificial intelligence for predicting the mechanical, electronical, optical, and functional properties of structural and nuclear materials under extreme environments. Research spans atomistic to continuum scales, providing a mechanistic understanding of deformation, irradiation damage, and failure, and integrates machine learning and explainable AI to develop predictive surrogate models that link simulations with experimental data. These approaches identify the key parameters controlling strength, ductility, and radiation tolerance, while also offering uncertainty quantification to accelerate materials qualification for nuclear energy systems.
In addition to nuclear structural applications, multiscale modelling frameworks are extended to electrochemical catalysis, hydrogen storage, and water splitting. Here, ab initio and quantum chemical software is utilized to modelling and AI tools are used to unravel reaction mechanisms, optimize catalytic interfaces, and design materials with improved efficiency and stability for sustainable energy conversion and storage.
By combining physics-based modelling with data-driven methods, the group delivers predictive and interpretable insights that support both materials roadmap and the broader development of advanced energy technologies.
The core research pillars of our group encompass the following key areas:
Multiscale Modelling of Nuclear Materials – linking atomistic, mesoscopic, and continuum scales to understand irradiation damage, deformation mechanisms, and mechanical property evolution in steels, Ni-based alloys, high-entropy alloys, and tungsten-based systems.
Artificial Intelligence and Explainable Machine Learning – developing predictive and interpretable models that connect experimental datasets with simulations, enabling accelerated qualification of structural materials and protective coatings for fusion and fission applications.
Protective Coatings and Functional Ceramics – modelling and AI-driven design of amorphous and doped alumina coatings for Eurofer97, addressing corrosion resistance, tritium permeation, and high-temperature stability in breeder blanket environments.
Energy Conversion and Storage Materials – applying multiscale modelling and AI to electrochemical catalysis, hydrogen storage, and water splitting, with the aim of optimizing catalytic interfaces and designing efficient, durable materials for sustainable energy technologies.
