Miguel H. Díaz

On May 20, 2014, Loyola University Chicago announced that they intended to hire Díaz as a professor despite a University of Dayton harassment allegation. A spokesman for Loyola said in an email, "We have reviewed the allegations raised against Miguel Diaz and our offer to him stands." He became a professor at Loyola on July 1, 2014.

After joining the University of Dayton, he was sought for analysis and comment by the national news media, especially upon the resignation of Pope Benedict XVI in February 2013. He currently holds the John Courtney Murray University Chair in Public Service at Loyola University Chicago where he continues to be sought by multiple media outlets for analysis and commentary.

Díaz gave his first speech on U.S. soil as ambassador on Friday, February 5, 2010, at St. John Vianney College Seminary in Miami, Fl. He spoke at the seminary's 11th Annual Fides et Ratio Conference on the relations between the U.S. Government and the Holy See. Ambassador Díaz attended St. John Vianney College Seminary and obtained a certificate in Pre-Theology.

He presented his credentials on October 2, 2009, and served until November 10, 2012.

Prior to his service as ambassador, he was a professor of theology at the College of Saint Benedict and Saint John's University in Minnesota. Díaz is the co-editor of the book From the Heart of Our People: Explorations in Catholic Systematic Theology and author of On Being Human: U.S. Hispanic and Rahnerian Perspectives, named "Best Book of the Year" by the Hispanic Theological Initiative at Princeton Theological Seminary. Díaz has taught religious studies and theology at Barry University, the University of Dayton and the University of Notre Dame. From 2001 to 2003, he taught and served as academic dean at St. Vincent de Paul Regional Seminary in Boynton Beach, Florida. He is a board member of the Catholic Theological Society of America (CTSA) and past president of the Academy of Catholic Hispanic Theologians of the United States (ACHTUS).
