About me

My research focuses on breast cancer in a very broad sense. We build our projects on the strong epidemiologic tradition and infrastructure of the Department of Medical Epidemiology and Biostatistics, and collaborate with several strong research groups and clinical networks. 

Research description

Main research interests

  • To determine genetic variants associated with prognosis of breast cancer (inherited alterations)
  • To identify novel breast-tumor specific markers for disease progression (somatic alterations)
  • To study the long-term breast cancer prognosis as well as the panorama of diseases in breast cancer survivors.
  • Mammographic screening and interval breast cancer
  • Better understanding of mammographic density and implementation for clinical use

Current supervision of PhD students

Scientific Networks

From 2014, member of the steering group for BRECT (Breast Cancer Theme Center), KI.

From July 2008, Deputy Director of CRisP Center financed by Swedish Research Council (PI: Henrik Grönberg) that aims on ‘Individualized prediction and prevention of breast and prostate cancer.

From 2007, member of the international Breast Cancer Association Consortium (BCAC). More than 60 groups worldwide contribute information on genetic and non-genetic factors. So far BCAC has identified more than 180 susceptibility SNPs.

From 2010, member of NorTwinCan (Nordic Twin Study of Cancer), the largest twin study on cancer in the world. The NorTwinCan team seeks to more accurately quantify the heritable and familial risk of various cancers through the creation of a unique database that pools information from twin and cancer registers in four Nordic countries (Finland, Denmark, Sweden, and Norway).
