Research Focus

Therapy resistance in cancer

Elucidating the molecular basis of therapy resistance in cancer is an unmet clinical need.

Our aim is to characterize the evolution of cancer therapy resistance. Based on preliminary results we hypothesize that therapy resistance is linked to the rare population DTP cells that survive treatment through the stabilization of transient drug-induced phenotypes, until mechanisms ensuring stable drug resistance emerge. Our aim is to characterize tumors during different stages of therapy to identify vulnerabilities of this adaptive process.

Effective targeting of DTPs will result in a paradigm shift, changing the focus from countering drug resistance mechanisms to preventing or delaying therapy resistance, leading to improved treatments of patients.

In 2020, we established a research consortium within the university, and successfully applied for funding from the FWF Doc-fund to establish an excellence-based graduate training program.
