She is co-principal investigator of the Million Women Study, a very large UK cohort study of women’s health, and sits on the steering committee for several international collaborations including the Collaborative Group on Hormonal Factors in Breast Cancer, the Endogenous Hormones and Breast Cancer Collaborative Group, and the Collaborative Group on Epidemiological Studies of Ovarian Cancer.
Gillian trained originally as a statistician and completed a PhD in statistics before becoming interested in epidemiology. Her main research interests are the roles of hormonal and other risk factors in the development of female cancers. She is particularly interested in risk factors and patterns of survival for molecular subtypes of breast cancer.
