Laufey Tryggvadóttir

Laufey received a BSc degree in biology from the University of Iceland in 1983 and MSc degree in epidemiology from the University of Western Ontario, Canada, in 1986. She is a clinical professor at the Faculty of Medicine, University of Iceland, and has been lecturer in epidemiology and human genetics, supervisor and member of PhD- and MSc committees since 1988. Laufey has been on the steering committee of the Nordic Summer School in Cancer Epidemiology from the outset (1990), and a supervisor and tutor since 1997.

Laufey has been on the board of directors for the Association of Nordic Cancer Registries since 1989. Current and recent collaborative projects include Avoidable cancers in the Nordic Countries, Nordic Obesity Surgery Cohort, Nordic Anti-reflux Surgery Cohort, Adult life after Childhood Cancer in Scandinavia (AliCCS), Collaboration on familial cancer in the Nordic countries, Nordic Occupational Cancer Study (NOCCA), Prognostic Factors, Treatment and Breast Cancer Survival in Nordic BRCA2 Mutation Carriers. Laufey is the Icelandic PI in Nordic follow-up studies of the MSD trial on HPV vaccination.

Laufey is in charge of epidemiological research at the Icelandic Cancer Registry and has a long-standing experience in cancer epidemiology. Special subjects of interest are environmental and genetic factors that affect cancer risk, and factors that affect survival of cancer patients, with a special focus on the epidemiology and biology of breast- and prostate cancer in BRCA2 mutation carriers.
