Sean Carroll, PhD
Carroll is a Senior Research Associate in Physics at the California Institute of Technology. He received his Ph.D. in 1993 from Harvard University. His research ranges over a number of topics in theoretical physics, focusing on cosmology, field theory, particle physics, and gravitation. He is the author of the upcoming "From Eternity to Here," about cosmology and the arrow of time.
Clifford Johnson, PhD
Johnson received his PhD. from the University of Southampton, U.K., and is currently a theoretical physicist at the University of Southern California. His research focuses on strongly coupled phenomena, which are important in a wide variety of physics topics, including quantum gravity, black holes, cosmology, string theory, and field theory. He is part of the ongoing international effort to use modern physics to understand and describe the origin, past, present and future of the universe.
Nick Warner, PhD
Warner is a leading expert on the conditions inside of black holes and has played an integral role in the development of string theory. Warner is one of the key figures in creating the new mathematical field of "mirror symmetry." He has been a Professor of Physics and Astronomy at USC since 1990 and Professor of Mathematics since 2003. He received his Ph.D. in 1982 from the University of Cambridge, where his dissertation advisor was the renowned physicist Stephen W. Hawking.
