About me

I am professor in infectious disease epidemiology since 2009. I began research in tumor virology in 1982, working with George Klein on Epstein-Barr virus and became professor in virology in 2001. Since 1989, my group has conducted Human Papillomavirus (HPV) research in the areas of molecular biology, immunology and vaccinology, clinical virology and epidemiology. Major ongoing projects include Swedescreen, the first started randomised trial of HPV-screening (since 1997), biobank- and registry-based follow-up studies of HPV vaccination (since 1999), the International Papillomavirus Reference Center (, the National Quality Registry of Cervical Cancer Prevention, the Nordic Information for Action eScience Center of Excellence ( and the European Union project on Excellence in Comparative Effectiveness Research (CoHeaHr).

Research description

My research is focused on cancer screening and tumor virology, especially human papillomavirus (HPV). Projects include large trials of HPV screening, Nordic follow-up studies of HPV vaccination and international networking efforts for large-scale molecular epidemiological studies for evaluation of the role of infections in cancer. By promoting the development and linkage of high quality key research infrastructures for cancer research such as cohorts, biobanks and registries, my research aim is to develop more effective health services for cancer control.
