The Department of Physics at the University of Jyväskylä invites applications for a Postdoctoral Researcher position in nuclear astrophysics, starting March 2, 2026, or as soon as possible thereafter. This fixed-term, two-year position (with possible extension) is part of the newly established Centre of Excellence in Neutron-Star Physics, funded by the Research Council of Finland. The Centre provides long-term funding, strong national and international research connections, and resources for research visits and conference travel. The successful candidate will join the Exotic Nuclei and Beams (IGISOL) team and collaborate with the nuclear theory group led by Prof. Markus Kortelainen. Research will focus on nucleosynthesis calculations and modeling of the rapid proton capture process in thermonuclear x-ray bursts and/or the rapid neutron capture process in neutron-star mergers. The position offers a unique opportunity to explore nuclear data and their impact on neutron-star physics, in collaboration with Finnish and international partners. Applicants must have a Ph.D. in theoretical or computational nuclear astrophysics, astrophysics, or a closely related field, completed before the start date. Essential qualifications include a strong background in nucleosynthesis and astrophysical simulations, proficiency in computational methods and programming (C++, Python, Fortran), and excellent communication and teamwork skills. Experience with neutron star physics, high-performance computing, and nuclear models is preferred. Candidates must be ready to work in an international research team and meet the University’s language requirements. The position offers a competitive salary (3600–4800 €/month gross, depending on qualifications and experience), determined by the university salary system (demand level 5–6), with a settling-in allowance and support for relocation. Additional benefits include resources for research visits and conference travel, and a vibrant, multidisciplinary research environment. The University of Jyväskylä provides excellent working conditions, a lively campus, and is located in a city known for its high standard of living, strong educational and cultural scene, and beautiful natural surroundings. To apply, candidates must submit their application via the University of Jyväskylä online application form by February 4, 2026. Required documents (in English, PDF format) include a CV, motivation/cover letter, publication list, degree certificate, and contact details for at least two references. Applicants must have a public ORCID profile. For further information, contact Prof. Anu Kankainen ([email protected]). The University values equality and diversity and encourages qualified applicants from all backgrounds to apply.
