Lee was born in New York City in 1955 and raised there and in Cincinnati. In September of 2001 he moved to Canada to be a founding member of the Perimeter Institute for Theoretical Physics, where he has been ever since. Lee's main contributions to research are so far to the field of quantum gravity. He was, with Abhay Ashtekar and Carlo Rovelli, a founder of the approach known as loop quantum gravity, but he has contributed to other approaches including string theory and causal dynamical triangulations. He is also known for proposing the notion of the landscape of theories, based on his application of Darwinian methods to Cosmology. He has contributed also to the foundations of quantum mechanics, elementary particle physics and theoretical biology. He also has a strong interest in philosophy and his three books, "Life of the Cosmos," "Three Roads to Quantum Gravity" and "The Trouble with Physics" are in part philosophical explorations of issues raised by contemporary physics. His latest book, "Time Reborn," will be published in April 2013 from Hooughton Mifflin Harcourt in the United States, Random House in Canada and Penguin in the UK.
