Christiane Nusslein-Volhard is a geneticist who studies the mechanisms of development. Her early work focussed on zebra fish, but she is best known for her studies of embryonic development in fruit flies, for which she was a joint recipient of the 1995 Nobel Prize in Physiology or Medicine.
By inducing mutations in fruit flies and observing the effects on their offspring, Christiane’s work has revealed the major events that make up the fruit fly’s embryonic development, as well as the genes that direct cells to form specific body parts. Her work has assisted the study of similar genes in humans, improving our understanding of the causes of congenital disorders.
