Brian Greene is a professor of physics and mathematics at Columbia University, and is recognized for a number of groundbreaking discoveries in his field of superstring theory. His books are widely read: The Elegant Universe was a finalist for the Pulitzer Prize and has sold more than a million copies worldwide; The Fabric of the Cosmos spent half a year on The New York Times bestseller list, and inspired The Washington Post to call him the “single best explainer of abstruse ideas in the world today.” His latest book, The Hidden Reality, also a New York Times bestseller, explores the multiverse.

Greene has had many media appearances, from Charlie Rose to David Letterman; his three-part NOVA special based on The Elegant Universe won an Emmy Award and a Peabody Award, and the four-part NOVA special based on The Fabric of the Cosmos has been nominated for a 2012 Emmy Award. A past recipient of an Alfred P. Sloan Foundation Fellowship and a National Science Foundation Young Investigator Award, Greene is co-director of Columbia’s Institute for Strings, Cosmology, and Astroparticle Physics (ISCAP), and is leading a research program applying superstring theory to cosmological questions. With producer Tracy Day, he is the co-founder of the World Science Festival.
