Emma Christoper is the author of "A Merciless Place: The Lost Story of Britain's Convict Disaster in Africa and How it Led to the Settlement of Australia," and "Slave Ship Sailors and their Captive Cargoes, 1730-1808." She is also the co-editor, with Marcus Rediker and Cassandra Pybus, of "Many Middle Passages: Forced Migration and the Making of the Modern World." Emma gained her PhD from the University College, London in 2002 and now holds an Australian Council Research Fellowship at the University of Sydney. Emma is currently writing the history of a small west African slave trading factory and also involved in making a documentary about this story. She has traced slaves from the factory to Cuba and Sierra Leone and the slave traders to the USA and Australia. Because of the unique set of documents related to the case it has, remarkably, been possible to find descendants of both groups today and so to reveal some of the global legacy of one small outpost of the transatlantic slave trade. Emma is researching and filming this story in Liberia, Sierra Leone, Cuba, the USA and Australia. Emma lives in Sydney, Austratlia.
