Umeå University, one of Sweden’s largest and most dynamic higher education institutions, is renowned for its world-leading research and high-quality education. The Department of Chemistry is offering a fully funded PhD position specializing in geochemistry, focusing on the occurrence and stability of smectite minerals with direct relevance to nuclear waste disposal. This research is supported by the Swedish Radiation Safety Authority (SSM) and aims to advance understanding of Swedish smectite-rich minerals as natural analogues for the bentonite barrier in the KBS-3 concept for final disposal of spent nuclear fuel.

The successful candidate will join a vibrant research group in molecular geochemistry, leveraging both theoretical molecular dynamics (MD) simulations and experimental techniques such as X-ray diffraction (XRD) to characterize smectite samples from various Swedish mineral deposits at the molecular level. The project integrates advanced computational and experimental approaches, providing a unique opportunity to contribute to the safe and sustainable management of nuclear waste.

As a PhD student, you will participate in research and postgraduate courses, with the possibility of engaging in teaching and departmental duties (up to 20%). The position is based at the Department of Chemistry, which is a leading research environment with strong ties to the Chemical-Biological Centre (KBC) and access to state-of-the-art experimental platforms. The research group has extensive experience in molecular geochemistry and offers a collaborative and supportive atmosphere.

Eligibility and Requirements: Applicants must hold a second-cycle degree or have completed at least 240 ECTS credits (with at least 60 ECTS at the advanced level), or possess equivalent foreign qualifications. Specific entry requirements include at least 90 ECTS credits in chemistry or a closely related subject, with a minimum of 15 ECTS credits at the advanced level in the specialization. Candidates should demonstrate a strong interest and background in geochemistry, geology, inorganic chemistry, and physical chemistry. Excellent oral and written English skills are essential. Merits include practical experience with spectroscopy or diffraction methods and basic programming skills. The selection process will also consider motivation, independence, collaboration skills, and problem-solving abilities.

Funding and Benefits: The position is fully funded for four years, with salary set according to Umeå University’s established PhD levels. PhD students enjoy comprehensive social benefits, including parental leave, holiday leave, and occupational health services. The physical workplace is in Umeå, Sweden, with a start date of March 1, 2026, or by agreement.

Application Process: Applications must be submitted via the university’s e-recruitment system Varbi by January 19, 2026. Required documents include a personal letter (max 2 pages), CV, degree certificates, transcripts, relevant publications (max 5), and contact information for two referees. The application can be written in English or Swedish.
