The focus of this research is to design and develop (physics-informed) hierarchical graph neural network architectures that can capture the complexity of multi-scale urban energy infrastructures. The PhD will explore how these models can represent spatial and temporal dependencies in systems, such as building energy demand, district heating and cooling, storage, and local electricity grids. A key goal is to translate methodological innovations in deep learning into practical tools for sustainable urban energy systems, supporting applications in forecasting, system optimization, flexibility management, and resilience analysis. The work will be carried out in close collaboration with our interdisciplinary teams at both Empa and EPFL, as well as external academic and industry partners. Your profile

Many skin injuries arise from non-adapted textiles and clothing. Frictional and heat/moisture accumulation problems favour the formation of injuries like blisters and pressure ulcers The PhD research will focus on characterizing and optimizing architectured fabrics and textiles using 3D micro tomography as a main tool to investigate tribological and thermal properties of different, architectured textiles (hydrophobic/hydrophilic) in different conditions (wet/moist). This will be complemented with tribological, thermal, optical (IR) and mechanical testing techniques. The research is performed in a holistic multidisciplinary approach in close collaboration with partners from UHA, France. The foreseen results of the project shall contribute to the development of optimized textiles used for medical and sports applications.Your contribution: Application and development of 3D X-ray microCT methods for studying wetting/evaporation in architectured textiles Studying and understanding the interaction in transient state between tribological and thermal properties in textiles by in-situ 3D and 4D microCT Design and execution of tribological, thermal, optical (IR) and mechanical tests on different types of textiles Data management, data treatment Reporting and publication Your profile

We are seeking three postdoctoral researchers to contribute to this project. The corresponding three main working areas are: Area 1 (Contact Person Dr Ehsan Hosseini)Multiscale mechanical experiments & hydrogen embrittlement: fracture toughness and fatigue crack growth experiments under high-pressure hydrogen environments, considering microstructure conditions of pipeline steels and welds.Modelling and simulation: development of a physics-based simulation framework (e.g., phase-field modelling) to predict hydrogen-assisted crack growth and long-term mechanical integrity of steels and welds. Area 2 (Contact Person Dr Bastian Rheingans)Weld microstructure and HE mitigation strategies: correlation of weld microstructures with hydrogen uptake and exploration of local treatments to “heal the weld.”Mobile non-destructive hydrogen detection: development of a field-deployable electrochemical method, benchmarked against lab-based approaches. Area 3 (Contact Person Dr Andreas Borgschulte)Hydrogen permeation in model systems: use of thin steel membranes to investigate hydrogen uptake, diffusion, and trapping under representative microstructural and stress conditions. The three postdocs will collaborate closely across these topics, working at the interface of advanced experimental testing, hydrogen analytics, materials characterisation, and modelling. Please explicitly state your interest as well as previous experience relevant to one of the above working areas in the letter of motivation. Your profile
