Tatsuya Nakanishi is an Associate Professor of Institute for Research in Humanities, Kyoto University, Japan. He has studied Hui Muslims’ (Chinese-speaking Muslims) intellectual activities by investigating Chinese, Arabic, and Persian historical sources. Particularly, he has explored how the Hui scholars have negotiated their religious belief and practice with non-Muslim Chinese people. As a fruit of this study, he published a Japanese monograph, Chūka to taiwa suru isurāmu: 17-19 seiki chūgoku musurimu no sisōteki eii (Islām in Dialogue with Chinese Civilization: Intellectual Activities of Chinese Muslims during the 17th-19th Centuries) (Kyoto: Kyoto University Press, 2013). Presently, he is grappling with how the Hui scholars after the 19th century responded to new Islamic ideas, such as thoughts of Ibn ʿArabī, Ibn Taymiyya, Aḥmad Sirhindī, and their proponents, from various regions of the Muslim world.
