Physicist, string theorist and author of The Elegant Universe, Brian Greene is one of the world’s leading theoretical physicists and a brilliant, entertaining communicator of cutting-edge scientific concepts. The Washington Post described him as “the single best explainer of abstruse concepts in the world today.”

In his national bestseller, The Elegant Universe, Greene recounted how the theories of general relativity and quantum mechanics transformed our understanding of the universe, and introduced us to string theory, a concept that might be the key to a unified theory of the universe. The book sold more than a million copies and became an Emmy and Peabody Award-winning NOVA special that Greene hosted.

His second book, The Fabric of the Cosmos, spent six months on The New York Times bestseller list and is currently being adapted into a four-part NOVA miniseries airing in the fall of 2011 on PBS. Greene's forthcoming book, Hidden Reality: Parallel Universes and The Deep Laws of the Cosmos, will be published in January 2011.

His latest book, Icarus at the Edge of Time, is a futuristic retelling of the Greek myth. The Wall Street Journal described it as “terrific” and Seed magazine called it “moving and successful" and "beautifully illustrated”. Greene and David Henry Hwang adapted the story for a symphonic performance in collaboration with composer Philip Glass; the world debut was in the spring of 2010.

In 2008, Brian Greene co-founded The World Science Festival. An annual event, its mission is to take science out of the laboratory, making the esoteric understandable and the familiar fascinating to the general public.

A graduate of Harvard and a Rhodes Scholar at Oxford, Greene is a professor in both Physics and Mathematics at Columbia University. He has written essays for NPR, Wired Magazine and The New York Times. He has appeared on a variety of programs, including Charlie Rose, Nightline and The Late Show with David Letterman, and he made cameo appearances in the films Frequency, Maze, and The Last Mimzy. 

Called "a charismatic speaker" by Publishers Weekly, he considers lecturing "a form of performance." Wrote Newsweek, "Greene's theatrical lectures -- which include lots of metaphors, cool 3-d visuals and dry humor -- routinely draw hundreds."
