Charles Birch is one of the world's leading geneticists. His early investigations into the insect world led to his interest in population ecology. He went on to explore the inter-reaction of humanity with the environment, studying genetics at Chicago University then Oxford. As Challis Professor of Biology at Sydney University, he helped lay the foundations for the new science of ecology. His search for a philosophy that could embrace both science and God culminated in what he calls ""an ecological model of God"".
