Area of research: Scientific / postdoctoral posts Starting date: 01.11.2026 Job description: Postdoc (f/m/d) Methods Development for the Micromechanical Characterization and Modeling of the Mechanical Behavior of Ion-Irradiated Nuclear Structural Materials within Materials Acceleration Platforms With cutting-edge research in the fields of ENERGY, HEALTH and MATTER, around 1,500 employees from more than 70 nations at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) are committed to mastering the great challenges facing society today. The Institute for Resource Ecology (IRE) conducts applied basic research into the protection of people and the environment from the effects of radioactive radiation. The Department of Structural Materials is looking for a Postdoc (f/m/d) Methods Development for the Micromechanical Characterization and Modeling of the Mechanical Behavior of Ion-Irradiated Nuclear Structural Materials within Materials Acceleration Platforms. Resistance to radiation-induced damage is a critical requirement for materials used in nuclear reactor construction, particularly given the demanding operating conditions expected in next-generation fission and fusion reactors. At HZDR, we pursue a range of strategies for developing innovative structural materials for nuclear applications. To do so, we study radiation resistance using ion-irradiated samples, which means characterizing very thin layers close to the sample surface. Our on-site Ion Beam Center gives us a real advantage here: irradiation, characterization, and model development sit close together, so results feed straight back into our models, from targeted sample preparation onward. The postdoc position advertised here centers on advancing the methods we use to characterize and model the mechanical behavior of ion-irradiated, innovative nuclear structural materials — materials that are currently being deployed across several national and international collaborative projects. Beyond the mechanical characterization of thin ion-irradiated layers by nanoindentation to quantify radiation-induced hardening and embrittlement, the position's main focus is on developing and applying numerical models that help us understand how radiation-induced microstructural damage translates into changes in macroscopic mechanical properties. Several open methodological questions remain here, for instance, how to derive robust property values (hardness, stress-strain behavior) from depth-resolved nanoindentation data on graded, ion-irradiated layers. Addressing them offers real scope for independent scientific contribution. A key part of this work involves integrating these methods into so-called Materials Acceleration Platforms (MAPs), which combine numerical simulations, ion irradiation, and fast experimental screening to search systematically for structural materials suited to innovative nuclear applications. The position is methods-driven at its core: rather than developing individual materials ourselves, our focus is on building, validating, and providing the micromechanical characterization and modeling tools that different materials-development projects across the MAP can draw on. We explicitly welcome your own methodological ideas and priorities — whether that means microstructure-based modeling, digital screening approaches, or new experimental analysis methods. You'll join an interdisciplinary team of currently four PhD students, three postdocs (including this position), and four senior scientists, supported by technical staff (workshop, metallography, engineering), and embedded in an international network of project partners. We actively support and encourage involvement in securing follow-up funding as part of the role.
