She was a paediatrician specialising in twins and as president of the International Society of Twin Studies worked closely with geneticists. She also worked as an inspector for the Human Fertilisation and Embryology Authority and was the author of several books on twins and multiples. Elizabeth died of cancer early in 2008.
