Paul Wallace teaches physics and astronomy at Agnes Scott College in Decatur, Georgia. His scientific work was in experimental nuclear physics and gamma-ray astrophysics, but his love of the history of astronomy drew him away from technical research. His unusual background and informal approach make him a sought-after speaker at churches, conferences, colleges, and retreats. His first book, Stars Beneath Us: Finding God in the Evolving Cosmos, was published in 2016.
