I have enjoyed reading and learning for as
long as I can remember. In 2015 I started my PhD studies in vaccination epidemiology at Karolinska Institutet. 
In 2016-2018 I had the opportunity to join the KI/Stockholm county research school for clinicians in epidemiology.

My PhD project is
conducted as a collaboration project between Karolinska Institutet and the 
Public Health Agency of Sweden.
Associate professor Anna Nilsson is my main supervisor and my co-supervisor are
Phd epidemiologist Malin Kark and associate professor Adam Roth. 


The project aims at:

  • Validating the Swedish Vaccination Register
  • Determining socioeconomic and medical risk factors for incomplete and untimely vaccination among Swedish infants
  • Evaluating what effect incomplete or untimely vaccination will have on infectious disease morbidity in a high-covarage setting
