Andrea Schaffer is an epidemiologist who has been primarily working on OpenSAFELY since 2022 and has over 15 years’ experience working with routine data. Her research interests include using routine data to understand how medicines are used in the population, with a particular interest in methods for evaluating the impact of policy interventions on medicine use and health outcomes. Prior to coming to the University of Oxford, she was based in Australia and obtained her PhD in pharmacoepidemiology from the University of New South Wales, and also has an MSc in Epidemiology (McGill University), and an MBiostat in Biostatistics (University of Sydney).
