Isabelle Ang is a sinologist, lecturer at Collège de France and full member of the Centre de recherche sur les civilisations de l'Asie orientale (CRCAO). She is the editor of the various collections published by Institut des Hautes Études chinoises at Collège de France. Her research focuses on the history and current status of Chinese religious cults, combining research into sources (epigraphic, historical and literary) with fieldwork. Her main subjects of study are: the history of the cult of Xu Xun 許遜 (239-374) in Jiangxi and its topicality; the history of the cult of the immortal Lü Dongbin 呂洞賓; the territories and links of the god-caves and blessed lands (dongtian fudi 洞天福地) of Jiangxi with local cults. In particular, she has published articles on the revival of the cult of Xu Xun in Jiangxi, the rituals associated with this cult in a clan village and the pilgrimage dedicated to Xu Xun in Xishan, near Nanchang.
