BMJ CONFIDENTIAL Liam Smeeth: Still hoping for Olympic gold

Liam Smeeth is professor of clinical epidemiology at the London School of Hygiene and Tropical Medicine. His interest in the causes of disease and the evidence base for its treatment was triggered by wondering about the evidence behind his advice to patients as a GP. One of his first studies helped to refute the link between the MMR vaccination and autism by using general practice records, and he is an enthusiast for the value of linking big data for the better understanding of disease.
