Fr. Hollenbach's teaching and research deals with human rights, religious and ethical responses to humanitarian crises and refugees, and religion in political life. He approaches these issues in a way shaped by Catholic social thought, contemporary theology and moral philosophy, as well as by social science approaches. In his free time, Fr. Hollenbach enjoys swimming, music, and watching college football and basketball games.
Before coming to GU, Fr. Hollenbach held the University Chair in Human Rights and International Justice and was Director of the Center for Human Rights and International Justice at Boston College. In 2015 he held the Cary and Ann Maguire Chair in Ethics and American History at the John W. Kluge Center for Scholars at the Library of Congress. He has taught often at Hekima University College in Nairobi, the Jesuit Philosophy Institute in Ho Chi Minh City, and the East Asian Pastoral Institute in Manila. He has conducted workshops for parliamentarians and for church heads in South Sudan on human rights in their newly independent country.
