Professor Dame Kay Davies

Kirsty Young's castaway this week is the scientist Professor Kay Davies. She has dedicated much of her life to finding a cure for the severest form of muscular dystrophy. Before she was 40, she had helped to develop the antenatal test which is now used around the world, then she isolated the gene sequence which could be instrumental in treating the condition. After years spent working on that, human trials for a possible treatment are about to begin. It's quite something for a woman who doesn't have an O-level in biology. Although, even as a child she did possess that critical quality crucial to scientific pioneers: "I loved solving problems," she says, "I was very tenacious and would sit in my room until I had finished the problem. I am a sticker."
