He has lectured extensively in North America, Eastern and Western Europe and Australasia on mathematics, the philosophy of science and the intellectual defence of Christianity. He has written a number of books on the interface between science, philosophy and theology. These include God’s Undertaker: Has Science Buried God? (2009), God and Stephen Hawking, a response to The Grand Design (2011), Gunning for God, on the new atheism (2011), and Seven Days that Divide the World, on the early chapters of Genesis (2011). His latest book, Against the Flow (2015), looks at the lessons for today’s society that one can draw from the life of the biblical figure, Daniel. Furthermore, in addition to over seventy published mathematical papers, he is the co–author of two research level texts in algebra in the Oxford Mathematical Monographs series.
Either human intelligence ultimately owes its origin to mindless matter; or there is a Creator. It is strange that some people claim that it is their intelligence that leads them to prefer the first to the second.”
He debated Richard Dawkins on “The God Delusion” in the University of Alabama (2007) and on “Has Science buried God?” in the Oxford Museum of Natural History (2008). He has also debated Christopher Hitchens on the New Atheism (Edinburgh Festival, 2008) and the question of “Is God Great?” (Samford University, 2010), as well as Peter Singer on the topic of “Is there a God?” (Melbourne, 2011). Furthermore, he has participated in public discussions on similar topics with many other academics on campuses around the world.
