is a leader in the application of particle and nuclear physics to astrophysics and cosmology and has made important contributions to the theory of big-bang nucleosynthesis, big-bang baryogenesis, the inflationary universe, and the nature of dark matter and its role in the formation of structure in the universe. He has been a Sloan Foundation Fellow and is a recipient of the Helen B.Warner Prize from the American Astronomical Society, the Julius Edgar Lilienfeld Prize from the American Physical Society, the Quantrell Award for excellence in undergraduate teaching at the University of Chicago, and the Halley Lectureship at Oxford University. Prof. Turner was chair of the NRC’s Committee on the Physics of the Universe. He has also been a member of other NRC committees, including the 2001 Astronomy and Astrophysics Survey Committee.
DONALD C.SHAPERO received a B.S degree from the Massachusetts Institute of Technology in 1964 and a Ph.D. from MIT in 1970. His thesis addressed the asymptotic behavior of relativistic quantum field theories. After receiving the Ph.D., he became a Thomas J.Watson Postdoctoral Fellow at IBM. He subsequently became an assistant professor at American University, later moving to Catholic University and then joining the staff of the National Research Council in 1975. He took a leave of absence from the NRC in 1978 to serve as the first executive director of the Energy Research Advisory Board at the Department of Energy. He returned to the NRC in 1979 to serve as special assistant to the president of the National Academy of Sciences. In 1982, he started the NRC’s Board on Physics and Astronomy (BPA). As BPA director, he has played a key role in many NRC studies, including the two most recent surveys of physics and the two most recent surveys of astronomy and astrophysics. He is a member of the American Physical Society, the American Astronomical Society, and the International Astronomical Union. He has published research articles in refereed journals in high-energy physics, condensed-matter physics, and environmental science.
TIMOTHY I.MEYER is a program associate at the NRC’s Board on Physics and Astronomy. Dr. Meyer joined the NRC staff in 2002 after earning his Ph.D. in experimental particle physics from Stanford University. His thesis concerned the time evolution of the B meson in the BaBar experiment at the Stanford Linear Accelerator Center. His work also focused on radiation monitoring and protection of silicon-based particle detectors. During his time at Stanford, Dr. Meyer received both the Paul Kirkpatrick and Centennial Teaching awards for his work as an instructor of undergraduates. He is a member of the American Physical Society, the American Association for the Advancement of Science, Phi Beta Kappa, and the Union of Concerned Scientists.
