Kieran studied philosophy in Australia, the United States and Germany in the 1970s and 1980s. He taught for a short period at the Australian National University, then spent nearly twenty years working for the Australian Government's overseas aid program. During this time he made numerous visits to countries in Africa, Asia and the Pacific, learning much from local people and from many fine aid workers dedicated to improving the lives of others. Praying for Sunlight, Waiting for Rain has its genesis in the visits Kieran made as an aid official to the highlands of Papua New Guinea.
