This doctoral position at KTH Royal Institute of Technology offers an exciting opportunity to advance the field of material physics and non-destructive diagnostics of polymers, particularly in nuclear environments. The project is part of a larger, interdisciplinary research programme funded by the Swedish Research Council (VR), focusing on improving the safety and lifetime of polymeric components used in nuclear power applications such as cables, seals, and protective materials.

The research will develop innovative, non-destructive methods for condition monitoring and lifetime assessment of polymeric materials. The doctoral student will combine low-field NMR with advanced material characterization techniques to establish quantitative relationships between molecular dynamics, microstructure, and functional degradation. Special attention is given to the influence of fillers, stabilization strategies, and active molecules on local segmental mobility, diffusion, and NMR relaxation, as well as how these properties evolve under controlled thermal ageing. The ultimate goal is to create robust, material-anchored condition indicators for reliable lifetime assessment in safety-critical environments.

The project is conducted in close collaboration with other work packages, including material development and AI-based modelling, providing access to a strong research environment with modern infrastructure and international collaborations. Supervision will be provided by Professor Richard Olsson and Dr. Payam Pourmand, ensuring expert guidance throughout the doctoral studies.

Applicants must meet the admission requirements for postgraduate education, including a relevant master's degree or equivalent, documented knowledge in polymeric materials, material characterization, or material physics, and English proficiency equivalent to English B/6. Selection criteria emphasize independence, collaboration, professionalism, and analytical skills. Experience with NMR, dielectric methods, spectroscopic techniques, ageing studies, polymer degradation, filled polymer systems, and programming or data analysis related to material characterization is considered meritorious.

The position offers full-time employment for up to four years, with a monthly salary according to KTH's doctoral student salary agreement and attractive employee benefits. The research environment at KTH is creative and dynamic, with a strong commitment to equality, diversity, and equal opportunities. Applications must be submitted through KTH's recruitment system by March 5, 2026, and should include a CV, application letter, diplomas, grades, certificates of language proficiency, and representative publications or technical reports. Certified translations are required for documents not in English or Swedish.

Join KTH Royal Institute of Technology and contribute to shaping the future of material science and polymer technology in nuclear safety. For further information, contact Professor Richard Olsson at [email protected].
