Prevention and treatment of chronic diseases

Testing physical activity and weight management interventions to reduce the risk of non-communicable diseases.

Most of the population are overweight, do not complete enough physical activity each week and sit for long periods every day, which increases the risk of developing non-communicable diseases and dying prematurely. Our focus is to save as many lives as possible through our pioneering world class research.

We are conducting world leading research that is testing health behaviour interventions to prevent and mange diseases such as cancer, cardiovascular diseases and mental illness.
