Matthew D. Walz, Ph.D.

Matthew Walz was born in New York, but grew up mostly in Ohio. He completed undergraduate studies at Christendom College, double-majoring in philosophy and theology and graduating as the valedictorian of the class of 1995. He did graduate studies in the School of Philosophy at The Catholic University of America (CUA). There he earned a doctorate in philosophy by completing a dissertation on Thomas Aquinas's understanding of free will.

Matthew has been teaching at the college level since 1998. As a graduate student, he taught for two years at CUA. Then he began teaching at Thomas Aquinas College, where he remained for eight years. Since 2008 he has been a professor in the Department of Philosophy here at the University of Dallas. He has served as Chair of the Philosophy Department for four years. In addition, in the summer of 2012, he began serving as the Director of the Philosophy & Letters and Pre-Theology Programs and became the Director of Intellectual Formation at Holy Trinity Seminary. In the summer of 2022, moreover, he was appointed Associate Dean of the Constantin College of Liberal Arts.

Matthew's research and writing focus primarily on medieval philosophy, ancient philosophy, and philosophical anthropology. Besides Aquinas, his favorite philosophical authors include Aristotle, Augustine, Anselm, and Wojtyla.

Matthew has been married since 1999 to his lovely wife Teresa. They have been blessed with eight children (two boys and six girls) who keep them busy, of course, but also joyful and grateful to God for His multitudinous gifts.
