Areas of Current Research Interest: Logic, Truth Theory, Metaphysics, Islamic Philosophy and Theology, Philosophy of Mathematics

Dr. Aladdin Yaqub’s areas of research include logic, truth theory, philosophy of mathematics, metaphysics, and Islamic philosophy and theology. In recent years, he has also developed broad expertise in the histories and philosophical theologies of the world’s monotheistic traditions.

Dr. Yaqub came to philosophy from a background in mathematics. Originally from Baghdad, Iraq, he earned his B.S. in Mathematics from the University of Baghdad in 1979. He completed his graduate studies at the University of Wisconsin–Madison, earning an M.A. in Mathematics in 1988, an M.A. in Philosophy in 1990, and a Ph.D. in Philosophy in 1991.

Before joining Lehigh University in 2006, Dr. Yaqub taught at the University of Wisconsin–Madison, Florida State University, Luther College, and the University of New Mexico. His scholarly work spans formal logic, theories of truth, metaphysics, Islamic philosophical theology, and the philosophy of mathematics.

Dr. Yaqub has published four books addressing truth theory, Islamic philosophical theology, logical theory, and metalogic with Oxford University Press, the University of Chicago Press, and Broadview Press. He is currently working on an annotated translation of Qur’anic exegeses by six early Muʿtazilite masters, a book project under contract with Brill.
