Research interests

The focus of my research is the development of new PET (positron emisson tomography) tracers with different applications, e.g. neurology, psychiatry and oncology. For my doctoral thesis, I have been working on the synthesis of new radiopharmaceuticals for the Translocator Protein (TSPO). The TSPO is a highly interesting target for neurodegenerative disorders, where inflammation plays a major role. Unfortunately, no ideal TSPO PET tracer exits. A new improved TSPO PET tracer would provide deeper understanding and more accurate diagnosis of several diseases, such as multiple sclerosis and Alzheimer's disease.

Techniques, methods & infrastructure

  • Drug development: synthetic organic chemistry, radiochemistry.
  • Characterization techniques: HPLC, NMR, UV-Vis and IR spectroscopy.
  • In vitro techniques: autoradiography, genotyping, metabolism, binding affinity experiments.


  • Synthesis of novel TSPO PET tracers: in vivo evaluation of [18F]VIE_TSPO_011 in NAFLD mice models (2018)
