The Clinical Epidemiology and Electronic Health Records Research Team, the THIN Database Research Group and the Primary Care Methodology Research Group are all led by Irene Petersen.


What we do

The team includes epidemiologists and statisticians who work on a range of clinical and methodological topics in collaboration with colleagues in London, UK and around Europe. 

Using different data sources and methods we work on topics such as: 

  • Does antidepressant treatment in pregnancy increase the risk of congenital heart defects?
  • What is the incidence and prevalence of type 2 diabetes in the UK and how is it pharmacologically managed?
  • Is it possible to predict postnatal depression using pregnant women's electronic health records?
  • How many people are prescribed antibiotics in a year, and how many antibiotics are they prescribed?
  • Does diabetes mellitus increase the risk of caesarean section?
  • Does smoking increase the risk of schizophrenia?
  • Common infections in patients prescribed systemic glucocorticoids.
  • New methods to deal with missing data.
