Research Focus

Molecular Tumorpathology

  • Genetic instability and signalling of GI-tract cancers
  • Epigenetic regulation of GI-tract cancers
  • Molecular mechanisms of targeted therapies (therapy prediction)
  • R&D molecular pathology/molecular diagnostics of FFPE-tissues specimens (e.g. NGS)

DKTK Research Topic

Molecular Diagnostics:

  • Development and Validation of Biromarkers for metastasis (Co-work with Prof. Martin Werner, Dr. Dr. Melanie Börries)
  • Integrated Molecular Diagnostics and advanced clinical application of tumor selected at the Molecuzlar Tumor Board Freiburg (Co-work with Prof. Nikolas von Bubnoff, Dr. Dr. Melanie Börries)

Further Collaborative Projects:

  • 2014: Detection of mutated, free circulating tumor DNA and noncoding RNA in plasma of patients with resectable, stage I-IIIA non-small cell lung cancer (Co-Work with Prof. Nikolas von Bubnoff)


Working Group Members DKTK
