Our Research

Below are details of publications arising from studies conducted using information provided by twins and their families here in Australia. Without the cooperation of the twins and their families none of this would have been at all possible and so we cannot thank then enough for their participation so far and we hope to continue with their support in the future. Where possible there are copies or links to the publications (some external sites may require registration).
