Who we are

Our research group in sarcoidosis epidemiology is part of the Chronic Inflammatory Diseases Epidemiology research section based at the Clinical Epidemiology Unit, Department of Medicine Solna.


Assistant professor

Elizabeth Arkema

Organizational unit: Group J Askling

Graduate Student

Marios Rossides

Organizational unit: Group J Askling
Epidemiologist and MD. Currently pursuing his doctoral studies in Epidemiology. Working primarily with sarcoidosis, but also with systemic lupus erythematosus.


Our vision and mission

Our overarching goal is to better understand the causes and consequences of sarcoidosis.

Specifically, our aims are to:

  • Identify risk factors for sarcoidosis

  • Reduce the time from symptoms to diagnosis

  • Improve treatment strategies for sarcoidosis

  • Minimize the long-term consequences of sarcoidosis

Our mission is to provide evidence-based answers to etiological and clinical questions using epidemiological methods.


Our data

Sweden’s high quality and comprehensive healthcare data allow us to conduct large-scale investigations of risk factors for and outcomes after sarcoidosis. These nationwide data from health and demographic registers form the basis of our data repository for sarcoidosis research. It is further enriched by the inclusion of clinical and laboratory data for about 1500 individuals included in the sarcoidosis clinical cohort at Karolinska University Hospital.

Our work is supported by grants from the Swedish Research CouncilHjärt-Lungfonden, Svenska Läkaresällskapet, SFO Epidemiology, and Karolinska Institutet Research Foundation.



Our work brings together the expertise of clinicians, immunologists and epidemiologists. Collaborations are essential for the exchange of expertise from all scientific fields and we welcome researchers interested in sarcoidosis research to contact us.

Currently, we work closely with the following entities:
