In 1983 he left MIT to join the US Peace Corps, where he served for two years in Kenya teaching physics and astronomy. Upon his return to the US in 1985 he became an assistant professor of physics at Lafayette College, in Easton, Pennsylvania, where he taught until his entry into the Jesuit order in 1989. He took vows as a Jesuit brother in 1991, and studied philosophy and theology at Loyola University Chicago, and physics at the University of Chicago before his assignment to the Vatican Observatory in 1993.

He is the author or co-author of four books exploring faith and science issues, including The Way to the Dwelling of Light (U of Notre Dame Press, 1998); Brother Astronomer (McGraw Hill, 2000); God's Mechanics (Jossey-Bass, 2007), and Would You Baptize an Extraterrestrial?
