Tim Spector is a British epidemiologist, medical doctor, and professor of genetic epidemiology at King's College London. He is widely known for his research on genetics, nutrition, and the gut microbiome, and he founded the long-running TwinsUK study, which has followed thousands of twins to better understand how genes and lifestyle influence health and disease. Over time, his work shifted toward exploring how gut microbes affect metabolism, immunity, and overall wellbeing, leading him to co-found the health science company ZOE, which focuses on personalized nutrition and large-scale nutrition research. Spector is one of the most cited scientists in his field and is also a bestselling author of books on diet and gut health, including The Diet Myth, Spoon-Fed, Food for Life, and Ferment.
