Research description

My research is on using exercise as a treatment for mild to moderate depression. I have worked with data from a large RCT, the Regassa study (, which explores exercise and internet-based cognitive-behavioral therapy as treatment for depression. 

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.
