The Twins Early Development Study

The Twins Early Development Study is one of the world's premier studies of how genes and environments shape our development from birth to young adulthood. The study is based at King's College London, one of the world's top 25 universities, under the leadership of Professor Robert Plomin, who has been ranked among the 100 most eminent psychologists in the history of science. The TEDS researchers use the latest discoveries in psychology and genetics to untangle the complex interplay between nature and nurture.
