Aun Hasan Ali's research focuses on the intellectual history of Shi'ism, including both the pre-modern and modern periods. In particular, he is interested in studying Shi'ism through the lens of the concept of tradition and social network theory. Ali is also interested in Shi'i law and legal theory, especially the interplay between shariah and legislation. His current project examines intellectual life in the city of Hillah in southern Iraq in the twelfth and thirteenth centuries CE. Ali is also preparing the final draft of an article in which he examines the relationship between Sunnism and Shi'ism through the lens of the issue of documentary evidence in Islamic law. His recent publications include a translation of a Persian chapter about the Qajar philosopher Abu'l-Hasan Jilveh in Philosophical traditions in Qajar Iran, set to be published by Brill in 2015, and two articles on Shi'i legal theory, classical and modern, in The Oxford Encyclopedia of Islam and Law.
