Tim Spector is Professor of Genetic Epidemiology and Head of the Department of Twin Research at King’s College London. He was one of the co-founders of the ZOE Covid Symptom study, which for which he was awarded an OBE. He has also written best-selling books about the relationship between what we eat and our health and well-being.

Tim was born in London in 1958 into a medical family. His mother was a physiotherapist and his father was an eminent pathologist, although Tim initially resisted his father’s encouragement to follow him into medicine. Once qualified, Tim specialised in rheumatology before switching to epidemiology. In 1992, he set up a large-scale research study of twins which now has more than 15,000 identical and non-identical twins taking part.

After a health scare in 2011, Tim became more interested in how we can influence the microbes in our gut to help us stay well. He has published several books on the science of eating well and is a pioneer in personalised food nutrition.

Tim lives in London with his wife, who is also a doctor.
