William Tang is the Chief Scientist at the Princeton Plasma Physics Laboratory (PPPL), the national laboratory for fusion research. He is also the Associate Director for the Princeton Institute for Computational Science and Engineering (PICSciE) which was recently established at Princeton University to stimulate progress in innovative computational science via interdisciplinary alliances involving computer science, applied mathematics, and prominent applications areas in the physical sciences and engineering disciplines. In October, 2006, the Chinese Institute of Engineers-USA (CIE-USA), the oldest and most widely recognized Chinese-American Professional Society in North America, presented him its Distinguished Achievement Award "for his outstanding leadership in fusion research and contributions to fundamentals of plasma science." After receiving a PhD. in Physics from the University of California, Davis in 1972 with dissertation research carried out at the Lawrence Livermore National Laboratory, he advanced to the Principal Research Physicist rank at PPPL and Lecturer with Rank of Professor in the Department of Astrophysical Sciences by 1979 and became a Fellow of the American Physical Society at that time. He successfully served as Head of the PPPL Theory Department, generally recognized as the premier plasma science theory group in the world, from 1992 through 2004. Under his leadership, theoretical research at PPPL was diversified into non-fusion areas -- especially high-performance computing activities. He played a prominent leadership role for the Department of Energy's development multi-disciplinary program in advanced computational science, SciDAC (Scientific Discovery through Advanced Computing). He is currently the Director of the Plasma Science Advanced Computing Institute for DOE's Fusion Energy Sciences Program. In research activities, he is internationally recognized for his leading role in developing the requisite kinetic formalism as well as the associated computational applications dealing with electromagnetic plasma behavior in complex geometries. He has over 200 publications (including more than 130 papers in peer-reviewed journals such as Science, Phys. Rev. Letters, Physics of Plasmas, etc.) and has presented more than 40 invited talks at major conferences and prominent venues. He has contributed strongly to teaching and research training in Princeton University's Department of Astrophysical Sciences for over 20 years and has supervised numerous successful Ph.D. students, who have gone on to highly productive scientific careers. Examples include recipients of the prestigious Presidential Early Career Award for Scientists and Engineers in November, 2000 and in June, 2005.
