Jones explores the dependency of all life and systems on Earth – ecological, biological and physical – on our nearest star. He explores the connections between those systems, and the connections between the various disciplines that study them, from astronomy to cancer prevention, from microbiology to the study of sleep. He also charts his own work and interests over fifty years against developments in a wide range of fields, showing how what was once seen as a narrow specialism has become a subject of vast scientific, social and political significance. Jones is Professor of Genetics at University College London and President of the Galton Institute.
