I am John Snow Professor of Epidemiology at Queen Mary University of London. My current interests are in cancer epidemiology and clinical trials, with special interest in prevention and screening.
My research activities are concentrated on cancer screening and early diagnosis. There is potential for considerable saving of lives from cancer if it were diagnosed at an earlier stage.
Our group investigates cancer evolution, with a focus on understanding how genetic changes influence disease progression, response to therapy and development of resistance. We particularly concentrate on gastrointestinal cancers such as colorectal, stomach and oesophageal cancer.
