My research interests include study design, biostatistical methods, and how to make the most of registers and other secondary data sources for pharmacoepidemiological studies. During 2020 to 2022 I worked part time at the National Board of Health and Welfare on issues concerning data quality in the national healthcare and social service registries. Starting in March 2023, I am working on issues linked to using healthcare data for research through the Clinicum initiative - organized methods support for clinical and translational research funded by KI and Region Stockholm.
