Research interests

Physical activity and sedentary behaviour in adults.

Main interests include: workplace interventions for promoting activity and reducing sitting time; measurement of physical activity and sedentary behaviour; secondary analysis of population based data sets for estimating physical activity and sedentary behaviour and their associations with health risks and outcomes; social marketing and mass media campaigns related to physical activity.
