Research interests

  • Radiochemical labeling of small molecules with medical radionuclides (especially 11C, 18F, 68Ga, 177Lu)
  • Implementation of tracer production for in-house use.
  • Development of novel radiolabeling methods using [11C]CO2-fixation chemistry.
  • Chemical synthesis of stable precursors for radiolabeling
  • In vitro preclinical evaluation of potential PET tracers (e.g. parameters like receptor binding affinity, ligand receptor kinetics, lipophilicity, plasma protein binding and metabolic stability)
  • Structures of special interest: bile acids, PARP inhibitors, muscarinic acetylcholine receptor ligands

Techniques, methods & infrastructure

  • Labs for handling open radioactivity (hot cells, radiosynthesis modules)
  • Radiochemistry of PET nuclides (especially 11C, 18F) provided by the AKH cyclotron
  • Organic synthetic chemistry
  • Analytical chemistry and structure identification (NMR, MS and other spectroscopic methods), chromatography (especially various HPLCs)
  • Radioligand binding assays
