Stephen M. Barr is Professor Emeritus of Physics at the University of Delaware and former Director of its Bartol Research Institute. His physics research centered mainly on “grand unified theories”; the cosmology of the early universe, including the origin of matter (“baryogenesis”) and dark matter; and the properties of fundamental particles. In 2011, he was elected to be a Fellow of the American Physical Society “for his original contributions to grand unification, CP violation, and baryogenesis”. He writes and lectures extensively on the relation of science and religion. Many of his articles and reviews have appeared in First Things, on whose Editorial Advisory Board he has served. He has also written for National Review, The Public Interest, Commonweal, The Wall Street Journal, and other national publications. He is the author of Modern Physics and Ancient Faith (Univ. of Notre Dame Press, 2003), A Student’s Guide to Natural Science (Intercollegiate Studies Institute, 2006), Science and Religion: The myth of conflict (Catholic Truth Society, 2011), and The Believing Scientist: essays on science and religion (Eerdmans, 2016). He was elected in 2010 to the Academy of Catholic Theology. He is the first president of The Society of Catholic Scientists, which he and a group of colleagues founded in June, 2016, and which has grown to 2,500 members. He and his wife Kathleen have five grown children.
