About me

Specialized in the methodological aspects of clinical epidemiology, I have a passion for teaching and for making cutting edge methodologies known and used by the research community. The overarching aim of my work is to, using epidemiological studies, provide information that will help patients and caregivers better understand chronic disease and disease course, and to make informed choices about therapeutic options.

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. 

Research description

As part of Johan Askling's research group on chronic inflammatory disease epidemiology, my team's work can broadly be divided in pharmacoepidemiological projects on treatments for rheumatic diseases and multiple sclerosis, and etiological studies with a focus on the familial aggregation of chronic inflammatory joint diseases. My research is funded by research grants from US-based Patient Centered Outcomes Institute (PCORI), the Swedish Research Council, patient organizations in Neurology and Rheumatology, and the MS Research Foundation (MS-forskningsfonden). My work in the Anti-Rheumatic Therapies In Sweden (ARTIS) project has been funded funded by post-authorization safety studies contracted between the Kaorlinska Institutet and several pharmaceutical companies.
