Leigh Ann Craig studies the history of medieval European religion, gender, and culture. Her present research focuses on the ways in which people from differing walks of life diagnosed and coped with disabilities which modern people would refer to as mental illness. In particular, she is exploring the question of how medieval people decided whether a given individual was suffering from a humoral imbalance (such as melancholy, mania, or frenzy) or from demonic possession. Her research is currently focused on this question as it appears in later medieval miracle stories. In support of this research, she spent the summer of 2009 as a seminar participant with the NEH Seminar “Disease in the Middle Ages” held at the Wellcome Library in London, and was a Fellow of the Summer Research Institute at Harris Manchester College, Oxford, in 2010.
