About me

My current research focuses on the consequences of sick leave and risk factors for sick leave using data from the Swedish Twin Registry, questionnaires and other sources. 

My PhD project was focused on using exercise as a treatment for mild to moderate depression. The data came from a large RCT, the Regassa study (http://www.regassa.se/sv/) and included treatment as usual and three exercise groups of varying intensity. 

Additionally I have worked on a project regarding risk and protective factors for fall injuries in elderly. In this project we used data from registers and the Stockholm Public Health Cohort.
