Offer Description

The Department of Physics is seeking to recruit aPostdoctoral Researcher inexperimental nuclear astrophysics startingJanuary 2027 or as soon as possiblethereafter,fora duration of 2 years.The position is fixed-term, as it is related to a research project. The research will be carried out within the newly established Centre of Excellence in Neutron-Star Physics 2026-2033 (https://neutronstars.fi/ ), funded by the Research Council of Finland. The Centre of Excellence status provides us with long-term funding, strong connections to related Finnish and international research groups, and generous resources for research visits and conference travels.

The local research team at the University of Jyväskylä, the Exotic Nuclei and Beams (IGISOL) group is led by Prof. Anu Kankainen. The group investigates properties of atomic nuclei by employing high-precision mass spectrometry as well as laser and decay spectroscopy at the IGISOL facility in the JYFL Accelerator Laboratory. The conducted research at IGISOL focuses on nuclear astrophysics, nuclear structure, neutrino physics, and fundamental interactions.

The selected postdoctoral researcher is expected to:

• Perform atomic mass measurements with the JYFLTRAP Penning trap and/or the Multi-Reflection Time-of-Flight Mass Spectrometer (MR-ToF-MS) at the IGISOL facility in JYFL-ACCLAB
• Contribute to the development of JYFLTRAP/MR-ToF-MS and their application to decay spectroscopy studies
• Participate in experiments at the IGISOL radioactive-ion-beam facility
• Present scientific results at international conferences and publish in peer-reviewed journals
• Supervise students and summer trainees.

Who should apply

The successful candidate will significantly contribute to cutting-edge experiments in nuclear astrophysics, in particular mass measurements and complementary spectroscopic studies in JYFL-ACCLAB.

Qualifications:

• Experience in ion trapping and charged-particle manipulation techniques
• Experience in mass spectrometry, preferably with a Penning trap and/or multi-reflection time-of-flight mass spectrometer
• Familiarity with the production of radioactive ion beams
• Strong background in nuclear astrophysics is considered as an asset
• Proficiency in computational methods, programming (e.g., Python,..) and data analysis
• Mentoring of less experienced team members (i.e. students)
• Ph.D. degree in nuclear physics, nuclear astrophysics or related field.

Strong motivation for experimental research and academic career, excellent written and oral communication skills in English, and the ability to work effectively in an international research environment are also considered as essential for the position.

Department of Physics

The primary areas of research at the Department of Physics are materials physics, nuclear physics and particle physics. In materials physics, the core research fields are the physics of nanomaterials and thin films, quantum matter and quantum technologies, light-matter interaction and physics and chemistry of nanoparticles. Nuclear physics concentrates on nuclear astrophysics, nuclear structure and applied accelerator-based research, and particle physics on the physics of the strong interaction and ultrarelativistic heavy-ion collisions, particle cosmology and neutrino physics. Starting January 2026, the Department hosts three Finnish Centre of Excellences (CoEs) funded by the Research Council of Finland: CoE in Quark Matter, CoE in Quantum Materials, and CoE in Neutron-Star Physics. Experimental research at the Department is conducted in the Accelerator Laboratory, the multidisciplinary Nanoscience Center (NSC) and in foreign research centers, such as CERN and FAIR.
