PhD Researcher in Radiochemistry | Chemiker (m/w/d)

Job Summary

This PhD position is part of the 'TRANSFER' research project, a joint initiative focused on nuclear safety and geological repository systems for high-level radioactive waste. As a doctoral researcher at Forschungszentrum Jülich, you will investigate the retention of radionuclides like 226Ra and 90Sr in carbonate-bearing claystones. Your day-to-day work involves conducting complex sorption and recrystallization experiments, utilizing advanced analytical techniques such as Raman spectroscopy and SEM, and applying geochemical-thermodynamic modeling to interpret data. You will collaborate with a multidisciplinary team of modelers to evaluate radionuclide migration across various scales. This role is highly attractive for early-career researchers seeking a structured doctoral program within the Helmholtz Association, offering access to unique scientific infrastructures, international networking through a dedicated graduate school, and the opportunity to contribute to critical environmental and energy research.
