TEDS twin Rosa talks about her interest in twin studies

My interest in twin studies began with my participation in TEDS 21 years ago. Twins, I discovered, offer an elegantly simple scientific method for investigating the relative role of nature and nurture in determining traits like behaviour, personality, and health.

TEDS have launched a new study called “Children of TEDS”, or CoTEDS for short
