My dissertation, entitled "Legal Justice, Medical Authority and Madness in Qing China," examines the medical assessments of insanity in Qing legal administration. It provides a historical analysis of the integration of medicine into the Qing legal system before the coming of modern medicine and Western psychiatry. Moving beyond the scope of mental hospitals, it tells a broader story of how the Qing state, through its judiciary system—an integral component of late imperial China bureaucracy—regulated and shaped perceptions of insanity.
