Research interests

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

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


Techniques, methods & infrastructure

Much of this work is conducted within the following population or case-control studies:

  • Austrian Hereditary Cancer National Study (ATHENA),
  • 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 (2022)
