Charles Robin Graham is professor emeritus of mathematics at the University of Washington, known for a number of contributions to the field of conformal geometry and CR geometry; his collaboration with Charles Fefferman on the ambient construction has been particularly widely cited. The GJMS operators are, in part, named for him. He is a 2012 Fellow of the American Mathematical Society. Graham received his Ph.D. from Princeton University in 1981, under the direction of Elias Stein.
