Hadi Qazwini is an educator and researcher. His scholarly interests are in Islamic intellectual history, with a focus on theology, law, and Imāmī Shīʿīsm. He completed his Ph.D. in Religious and Islamic Studies at the University of Southern California. His dissertation, titled “The Islamic Debate on Juristic In/Fallibility (al-takhṭiʾa wa al-taṣwīb) and the Construction of Competing Orthodoxies,” explores the intellectual and practical underpinnings of the debate in Islamic legal theory over whether all legal experts are correct (kullu mujtahid muṣīb). In addition to pursuing the academic study of Islam, Hadi obtained advanced training in the Shīʿī seminary (al-ḥawza al-ʿilmiyya) in Qum, Iran, specializing in the traditional study of Islamic thought and practice. He recently published a peer-reviewed article in Islamic Studies entitled “Heir of the Prophets: Veneration of Ḥusayn b. ʿAlī and the Socio-Religious Positioning of Twelver Shiism.” He is in the early stages of writing a book, tentatively titled Islam and the Problem of Truth: An Intellectual History. In addition to his scholarly work, Hadi serves in several non-profit organizations in the areas of higher education and international development and relief.
