Research

My current position is a postdoctoral researcher in the E-MOVE project (funded by Research Council of Finland) and a project funded by the Turku Urban Research Programme, where the aims are to investigate the associations between environmental factors (such as greenness) and physical activity and health using the Centre for Population Health Research cohorts.

My PhD thesis at the Turku PET Centre (defence 8/2025) studied the effects of reducing sedentary behavior on cardiovascular health.
