Hereditary Breast and Ovarian Cancer Syndrome; Molecular Epidemiology

Research interests

My research interests cover the following aspects of hereditary breast and ovarian cancers:

  • Epidemiology and prevention
  • Cancer risk prediction models
  • Quality of life and supportive cancer needs
  • Healthcare delivery services for the high-risk cancer population

Techniques, methods & infrastructure

My group provides genetic testing to patients with or without cancers that may be suspected of having a BRCA or related genes alteration. With patient consent, data and samples are collected for national and international clinical trials to better understand the risk factors and functions of BRCA and related genes and their impact on therapy.

Most projects are conducted using the data from the Austrian Hereditary Cancer Biobank and Register Study (ATHENA) using advanced lab techniques, epidemiological designs and statistical analyses, and in collaboration with the following international consortiums:

  • International BRCA1/2 Carrier Cohort Study (IBCCS)
  • Consortium of Investigators of Modifiers of BRCA1/2 (CIMBA)
  • Evidence-based Network for the Interpretation of Germline Mutant Alleles (ENIGMA)


  • Identification and molecular analyses of brain metastasis in breast cancer patients (BRCAbrain) (2022)
    Source of Funding: Medical University of Vienna, CCC Initiative Krebsforschung Research Grant
    Principal Investigator
  • Precision medicine for breast cancer: multi-omics towards predicting complete remission and avoiding surgery, PREDICTOME (2021)
    Source of Funding: WWTF (Vienna Science and Technology Fund), Life Sciences Call 2020 - Precision Medicine
    Principal Investigator
  • Austrian BRCA‐associated metastatic breast cancer registry (2019)
    Source of Funding: Pfizer, Research Grant
    Principal Investigator
  • BRCA-P - Prospectively randomized place-controlled phase 3 study to determine the effect of denosumab on breast cancer prevention in BRCA1 mutation carriers (2019)
    Source of Funding: U.S. Department of Defense, Breast Cancer Research Program Breakthrough Award - Funding Level 4
    Coordinator of the collaborative project
