Commencement date: as soon as possible

Work location: Geesthacht

Application deadline: November 12th, 2026

The Institute of Material and Process Design at the Helmholtz-Zentrum Hereon is offering a 4-year PhD position in the field of computational materials engineering, machine learning, and digital twins for advanced lightweight materials. The focus of the PhD project will be the development of a physics-guided digital twin framework for magnesium alloys by integrating experimental characterization, crystal plasticity, phase-field modeling, precipitation modeling, and machine learning approaches to establish quantitative composition-process-structure-property relationships. Building upon recently developed machine-learning approaches for structure-property prediction in extruded magnesium alloys, the project aims to advance toward a next-generation Integrated Computational Materials Engineering (ICME) framework capable of predicting microstructure evolution and resulting mechanical properties across previously unseen processing conditions and material states.

The candidate will work closely with interdisciplinary teams combining expertise in magnesium alloy development, thermomechanical processing, crystal plasticity, phase-field modeling, machine learning, and advanced experimental characterization.

The objective of the project is to bridge the gap between purely data-driven materials modeling and mechanistic microstructure simulations by combining crystal plasticity, dynamic recrystallization, precipitation kinetics, and machine learning into a unified digital-twin framework. The resulting methodologies shall enable accelerated alloy and process design by leveraging experimentally validated physics-guided surrogate models with improved extrapolation capabilities beyond the limits of conventional machine-learning approaches. This work directly contributes to the digital transformation of materials development and manufacturing technologies for future lightweight engineering applications.

Equal opportunity is an important part of our personnel policy. We would therefore strongly encourage qualified women to apply for the position.
