Christopher White received his PhD in the Committee on the Study of Religion at Harvard University, where he studied science, technology, spirituality and culture in modern Europe and America.  He is particularly interested in the cultural history of religion and science, media technologies, spirituality and popular culture.  He has published articles on these and other subjects in scholarly journals and edited books, including articles in Religion in American Culture and the American Historical Review.  His first book, Unsettled Minds: Psychology and the American Search for Spiritual Assurance (California: University of California Press, 2009) examined how modern Europeans and Americans used psychological and medical insights to fashion new, more scientific ways of testing, analyzing and sometimes even fostering religious trances, visions and experiences.  His second book, Other Worlds: Spirituality and the Search for Invisible Dimensions (Harvard University Press, 2018), examined the cultural history of the idea that the universe has hidden dimensions, spaces and worlds.  Other Worlds won an inaugural book prize from the ISSR.
