He is currently investigating the relationship between fiscal policy and religious protest in early Islam. He also has ongoing projects comparing the institutions of excommunication in Islam, Christianity and Judaism; and investigating the development of Islamic canonical revenues, ghanīma, fayʾ, kharāj, khums, anfāl, ṣadaqa, and zakāt, the ways in which these terms overlap and relate to each other, and the ways in which they were both practically applied and conceptualized by early Islamic jurists and thinkers.
He is also working on a book entitled “Agents of the Hidden Imam: the Birth Pangs of Twelver Shiʿism, 850-950 CE.” He has published, or has articles forthcoming in Iranian Studies, Comparative Islamic Studies and the Journal of Arabic and Islamic Studies.
