We are seeking an ambitious Postdoc candidate to advance radionuclide therapy as an effective and widely accessible treatment for cancer patients. If you are passionate about contributing to cutting-edge cancer research and making a real difference in patients' lives, we encourage you to apply.

In radionuclide therapy, a tumor-targeting vector is coupled to a therapeutic radionuclide to specifically irradiate tumor lesions from inside the body. This approach allows for the delivery of a high radiation absorbed dose to (metastasized) tumor lesions, while sparing healthy tissues. Despite the high potential of treatment, we currently do not know which type of radionuclide is most effective to kill cancer cells and what is its underlying mechanism of action.

Within this NWO funded consortium project UNRANU; we aim to unravel the radiobiological effects of radionuclide therapy and contribute to novel production methods for therapeutic radionuclides and patient-specific treatment.

Your primary task will be to investigate the radiolabeling of tumor-targeting vectors like small molecules and microspheres. This will involve assessing the purity and quality of radionuclides, followed by the radiolabeling of small molecules and microspheres with various radionuclides for cancer treatment. You will also play a key role in developing vectors such as microspheres and small molecules, optimizing radiolabeling procedures, conducting quality control and stability tests, and managing radioisotope waste.

Effective collaboration is essential for this role, particularly with researchers involved in radioisotope production at Delft University of Technology, and those utilizing the radiolabeled vectors for internal radionuclide therapy in tumor cell and animal models at Radboudumc and Erasmus Medical Center.

Tasks and responsibilities:

• Investigate purity and quality of radionuclides.
• Radiolabel to several vectors like small-molecules, DTPA and microspheres with different radionuclides.
• Optimize vectors, including small molecules and various microspheres that can be labeled with radioisotopes or directly activated by neutrons in a research reactor, to improve radiolabeling efficiency. Additionally, investigate the radiolabeling percentage, shelf life of the formulation, stability in saline, blood, and serum, as well as waste products and other related factors.
• Investigate the stability, biodistribution of the vector-radionuclide constructs in biological models (cell-lines, organoids and mice tumor models).

What we offer you:
We offer you the opportunity to work within a large consortium and maintain close connections with various stakeholders from academia, industry, and society (e.g. TU Delft, ErasmucMC, NRG|PALLAS, AlfaRIM, HUB Organoids, MILabs, Quirem Medical, RTM, Siemens Healthineers, TerThera, URENCO, Von Gahlen, VSL RIVM, Wetenschapsknooppunt, patient organisations) to plan, discuss, and perform research in a stimulating environment.

• Masters degree in Pharmacy, Clinical Technology, Chemistry, Biomedical Sciences, Life Science, health physics or equivalent.
• Experience with working in a (radio)chemisch of (radio)pharmaceutisch laboratorium.
• Permit to work with radioactivity (or willing to obtain this permit).
• Well-developed communicational and social skills directed towards working in a team.
• Strong analytical and problem-solving skills.
• Enthusiastic and highly motivated to successfully complete a Postdoc.

Fixed-term contract: 2 year with a possible extension.
