Tim Key's main interests are the roles of diet and hormones in the aetiology of cancer, particularly cancers of the breast, prostate and colon, and the health status of vegetarians and vegans.
He currently works mostly on the European Prospective Investigation into Cancer and Nutrition (EPIC), as the principal investigator of the Oxford cohort of 60,000 subjects, including 30,000 people who don’t eat meat.
He also co-ordinates the Endogenous Hormones and Breast Cancer Collaborative Group.
Tim Key has worked as a cancer epidemiologist at the University of Oxford since 1985.
