Sonia was born and brought up near Manchester. She attended the University of Glasgow, graduating in 1968 with a degree in Botany. For several years, Sonia worked as editor of a scientific journal and in 1985 began to study printmaking at Morley College. As a result of her new interest Halfmoon Printmakers was formed with fellow artists Pip Carpenter and Susie Perring. Sonia is a member of the Greenwich Printmakers Association and of the Printmakers Council. She has exhibited throughout the UK since 1993, and her work has proved particularly popular in the Royal Academy Summer Exhibition. Sonia grew up surrounded by a selection of different animals including Hilary the pig who would let Sonia ride on her back. It is clear that the natural world still exerts an important influence on her work.
