Duane Alexander Miller is a researcher and lecturer in Muslim-Christian relations at The Christian Institute of Islamic Studies. He holds a BA in Philosophy from the University of Texas at San Antonio, an MA in Theology from St Mary's University in San Antonio, a diploma in Arabic from the Kelsey Language Institute in Jordan, and a PhD in Divinity from the University of Edinburgh in Scotland.

His doctoral research was on the contextual theologies proposed by Christian converts from Islam--what do they claim to know about God, and what attracted them to the Christian faith? The thesis is due for publication in 2016 as Living among the Breakage: Contextual Theology-making and ex-Muslim Christians(Pickwick, 2016).

After studying Arabic, the Millers moved to Nazareth of Galilee, which is a Muslim-majority, Arab city in Israel. There he was the founding academic dean of Nazareth Evangelical Theological Seminary (NETS). He also served as lecturer in church history and theology for the seminary. Duane has also taught at the University of Texas at San Antonio, the University of Edinburgh, and St Mary's University.

Dr. Miller has published numerous articles and chapters on the topics of Christian converts from Islam, the history of Protestant missions in Ottoman Palestine, and contemporary evangelicalism in the Middle East. He is author of Two Stories of Everything: The Competing Metanarratives of Islam and Christianity (2016), which seeks to understand the two faiths not as alternative religions, but as accounts of the entirety of history, from Creation to the final judgment. He is also co-author of Arab Evangelicals in Israel (Pickwick, 2016).
