Christopher Barry Collins is a cosmologist who has written many papers with Stephen Hawking. He is a professor emeritus of applied mathematics at the University of Waterloo.[1]

Collins earned his Ph.D. in 1972 from the University of Cambridge under the supervision of F. Gerard Friedlander.[2] Among his works with Hawking is a 1973 paper that uses the anthropic principle to provide a solution to the flatness problem.[3][4][5]
