My research focuses mainly on volume and temporal patterns of physical activity and sedentary behaviour and their associations with health. I'm particularly interested how physical activity and sedentary time are associated with cardiovascular diseases and perceived health.

Research interests

  • Measurement of physical activity and sedentary behaviour
  • Physical activity profiles
  • Health effects of exercise
