Research interests

My main research focus is primarily concerned with tumor immunology and immuno-oncology (IO). In particular I am investigating the role of therapy-induced (i.e. chemotherapy, radiotherapy) DNA damage and it's correlation with DNA and RNA sensors, endoplasmic reticulum (ER) stress response, immunogenic cell death (ICD), type I and type II interferon (IFN) induction, immune cell infiltration and clinical outcome in solid human malignancies (i.e. colorectal liver metastases).

Techniques, methods & infrastructure

  • Cell culture techniques (i.e. antibody-dependent cell-mediated cytotoxicity & phagocytosis assay)
  • Molecular biology techniques (i.e. IHC, IF, ICC, RT-qPCR, ELISA, western blot)
  • Imaging techniques (i.e. laser scan-, fluoreszence- or light-microscopy)
  • Flow cytometry (FCM), imaging flow cytometry (IFC)

Our Surgical Research Laboratories are endowed with various instruments for standard techniques in molecular biology, cell culture, protein biochemistry and immunology. They are located within the Anna Spiegel Research Building, also known as the „Center of Translational Research“ of the Medical University of Vienna, which is equiped with Core Facilities for Genomics, Proteomics, Flow Cytometry and Imaging, providing scientists easy access to state-of-the-art high-end equipment and cutting edge technology to address highly sophisticated research questions.

Furthermore, our studies are arried out within the frames of the Immunology Research Cluster (IRC)Comprehensive Cancer Center (CCC) Research Cluster Immunology and InflammationColorectal Cancer Unit (CCC-CRC) and the Ludwig Boltzmann Institute Applied Diagnostics (lbi:ad).
