Research Areas

My main areas of research are

  • Sexual health epidemiology with particular focus on the interplay between sexuality and general physical and mental health
  • Classic descriptive and analytical epidemiology on cancer and autoimmune diseases, notably HPV-associated cancers, rheumatoid arthritis, lupus erythematosus, inflammatory bowel diseases and multiple sclerosis.

I am the PI of Project SEXUS, a large, prospective population-based cohort study aimed to shed light on the sexual health and well-being of the Danish population as well as on the poorly understood interplay between sexual health and ill-health on one side and general physical and mental health on the other.
