Paul J. Steinhardt is the Albert Einstein Professor in Science and Director of the Princeton Center for Theoretical Science at Princeton University, where he is also on the faculty of both the Department of Physics and the Department of Astrophysical Sciences. He received his B.S. in Physics at Caltech in 1974; his M.A. in Physics in 1975 and Ph.D. in Physics in 1978 at Harvard University. He was a Junior Fellow in the Harvard Society of Fellows from 1978-81 and on the faculty of the Department of Physics and Astronomy at the University of Pennsylvania from 1981-98, where he was Mary Amanda Wood Professor from 1989-98. He is a Fellow in the American Physical Society and a member of the National Academy of Sciences. He shared the P.A.M. Dirac Medal from the International Centre for Theoretical Physics in 2002 for his role as one of the architects of the inflationary model of the universe; the Oliver E. Buckley Prize of the American Physical Society in 2010 for his contribution to the theory of quasicrystals; and the John Scott Award in 2012 for his work on quasicrystals, including the discovery of the first natural quasicrystal. In 2012, he was named Simons Fellow in Theoretical Physics; Radcliffe Institute Fellow at Harvard; and Moore Fellow at Caltech. He is the author of over 200 refereed articles, 100 reviews and popular articles, nine patents, four patents pending, three technical books, numerous popular articles, and, in 2007, co-authored Endless Universe: The Big Bang and Beyond, a popular book on contemporary theories of cosmology. He is one of the co-discoverers of icosahedrite, the first natural quasicrystal, and, in 2011, led a successful geological expedition to Chukotka in Far Eastern Russia to find new information about its origin and retrieve more samples.
