Molecular Oncology

Our group’s main focus is on pancreatic ductal adenocarcinoma (PDAC). We try to increase understanding of the molecular underpinnings of this fatal disease, for which patients are in dire need of additional potent therapeutic options. We work on oncogene dependency, metabolic vulnerabilities and tumor-stromal crosstalk at the levels of anti-tumor immune response and tumor cell interaction with cancer associated fibroblasts and the extracellular matrix. Based on gained knowledge we explore new targeted and immuno-therapeutic options in preclinical translational settings and model systems. Currently, we are exploring synergistic implications of indirect interference* with the activity of the virtually omnipresent and central oncogenic driver in PDAC: mutant KRAS.

Model Systems/Samples

  • State of the art genetic endogenous murine models (GEMMs) for PDAC
  • 2D and 3D cell culture systems including patient derived PDAC organoids
  • Patient derived samples


  • In vivo PDAC GEMM therapy trials
  • Small animal magnetic resonance and ultrasound imaging
  • Temporo-spatially controlled in vivo genetic perturbation of specific cell-types of the tumor stroma in PDAC GEMMs
  • In vitro genetic manipulation
  • Multiplex immunohistofluorescence/-chemistry
  • Flow cytometry and (imaging) mass cytometry (collab.)
  • Metabolomics (collab.)
  • Proteomics (collab.)
  • Genomics/Transcriptomics (collab.)
  • Analysis of the impact of targeted therapy approaches on human immune cells


Collaborations with groups from the Medical Faculty and with external experts exist and are continuously being intensified, particularly with a focus on the interconnection between oncogenic signaling dependency and tumor-immune-escape. Based on our collaborations and the locally available core facilities we have access to all -omics approaches, advanced microscopy, high-dimensional flow cytometry and (imaging) mass cytometry.
