PostDoc (f/m/d) Functionalization, radiolabeling and characterization of complex protein assemblies

As a member of the Helmholtz Association of German Research Centers, the HZDR employs about 1,400 people. The Center's focus is on interdisciplinary research in the areas energy, health and matter.

At the Institute of Radiopharmaceutical Cancer Research scientists from the fields of physics, chemistry, biology, pharmacy, immunology, medicine and IT develop innovative radiopharmaceuticals and novel tools for functional characterization, improved imaging and personalized treatment of tumors.

As part of the Institute, the Department of Radionuclide Theragnostics invites applications as PostDoc (f/m/d) Functionalization, radiolabeling and characterization of complex protein assemblies.

The position will be available from 1 January 2022. The employment contract is limited to two years.


The successful candidate (f/m/d) will work on an interdisciplinary European project as part of a well-established radiopharmaceutical science research team and the responsibilities will include, but are not limited to:

  • Carry out cutting-edge research in the areas of radiochemistry, biology and biochemistry with particular focus on the modification and characterization of protein assemblies and nanoparticle-protein complexes
  • Propose, evaluate, interpret and validate appropriate radiolabeling protocols for complex protein assemblies
  • Investigate and evaluate the stability and functionality of radiolabeled molecules in vitro by cell binding and uptake studies
  • Perform experiments in a state-of-the-art radiochemistry laboratory infrastructure, deploy novel technologies and collaborate with internal and external partners to promote the project
  • Quality control and quantification of radioconjugates by Radio High Performance Liquid Chromatography (Radio-HPLC), Radio Thin Layer Chromatography (Radio-TLC) and Size Exclusion Chromatography (SEC) in the radiochemistry lab environment
