Research interests

I am leader of the Nutritional Epidemiology Group which I established at the University of Leeds since 1994. It is a research-intensive group to create, advance and disseminate nutrition research to make an impact on population health. I am also a founder member of the new professional organisation - the Association for Nutrition which has responsibility for registration of nutritionists in the UK

My main areas of research are:

  • Nutritional epidemiology
  • The role of diet in chronic disease aetiology
  • Diet-gene interactions
  • Assessment of nutrition interventions
  • Development of dietary assessment methods

My major research project over the last few years has been the UK Women's Cohort Study which has detailed information on diet and cancer incidence in 35,000 British women. Other major research activities include the evaluation of the school fruit and vegetable scheme; an intervention to improve school lunchboxes; and a study of caffeine consumption in pregnancy and its effect on birthweight.

In recognition of my work in public health nutrition and epidemiology, I held one of the first DoH/NHS Career Scientist Awards for Public Health (2001-2006).
