Bogdan Andrei Bernevig Physics Department, Stanford University, Stanford, California 94305 (bernevig@stanford.edu). Mr. Bernevig is a Ph.D. candidate at Stanford University, where he is studying a number of theoretical aspects of spintronics and spin manipulation in semiconductors. His doctoral advisor is Professor Shoucheng Zhang, the co-director of the IBM–Stanford Spintronics Science and Applications Center. A native of Bucharest, Romania, Mr. Bernevig won his country's Physics Olympiad competition for high school students for four consecutive years (1994–1997), receiving gold and silver medals in the subsequent international competitions in his junior and senior years, respectively. He entered Stanford as a President's Scholar. In 2000, he won the David S. Levine Award for the most outstanding junior physics major, and he was a finalist for the American Physical Society 2000 LeRoy Apker Award for outstanding achievements in physics by undergraduate students. In 2001, Mr. Bernevig received both a bachelor's degree in physics and a master's degree in mathematics.

Shoucheng Zhang Physics Department, Stanford University, Stanford, California 94305 (sczhang@stanford.edu). Dr. Zhang received a B.S. degree in 1983 from the Free University of Berlin, Germany, and a Ph.D. degree in 1987 from the State University of New York at Stony Brook. He was a Postdoctoral Fellow at the Institute for Theoretical Physics (ITP) of the University of California at Santa Barbara from 1987 to 1989 and a Research Staff Member at the IBM Almaden Research Center from 1989 to 1993. In 1993, he joined the faculty at Stanford University, where he is now a professor of physics. Professor Zhang is well known for his research on high-temperature superconductivity, for which he proposed a unifying theory of antiferromagnetism and superconductivity based on the SO(5) symmetry. In 2004 he co-discovered a new law governing the dissipationless spin transport in semiconductors that could be the basis for a new generation of low-power, spin-based computing devices. Prof. Zhang is the co-director of the IBM–Stanford Spintronics Science and Applications Center.
