Join a current study

Are you a twin or triplet? A very precious gift that only you can give is the donation of your time to a twin study. By participating in twin studies, you'll be helping researchers to better understand what contributes to our health and happiness.

Below are our latest studies seeking twins and triplets. You'll find there are many ways to get involved - and often it is as simple as completing a questionnaire but this can be invaluable to research.
