Dr. Teruaki Moriyama is an Associate Professor in School of Theology at Doshisha University (Kyoto, Japan), and a Visiting Researcher in the Prince Alwaleed bin Talal Center for Muslim-Christian Understanding (ACMCU) at Georgetown University. He received his M.A.(History) from Tokyo Metropolitan University in 1999, and conducted his research in Damascus from 2001 to 2003 as a Chercher Associé in Institut Français d’Études Arabes du Damas (IFEAD). In 2009, he defended his dissertation in History of West Asia from the University of Tokyo. The dissertation analyzed how medieval Hadith scholars, who called themselves ‘Ashab al-Hadith,’ compiled, distributed and used the biographical local histories, such as History of Baghdad by al-Khatib al-Baghdadi (d. 1071), in their scholarly activities. From 2010 to 2013, he worked as a Research Fellow in the Japan Institute of International Affairs, and joined faculty of the School of Theology at Doshisha University in 2013. Since that, he has taught Qur’an and Hadith studies, history of the medieval West Asian Muslim society, and political and social situations in the modern Middle East. The title of his research project at ACMCU is “A Study on Linkage between Scholarly Activities of ‘Ashab al-Hadith’ and Formation of the Sunnis.” This project is a joint international research with Dr. Jonathan A. C. Brown and his colleagues, which is supported by Japan Society for the Promotion of Science Fund for the Promotion of Joint International Research (Fostering Joint International Research) (16KK0043).
