FOR VICE PRESIDENT WICK HAXTON University of Washington

Haxton received his PhD from Stanford in 1976. After a year as a researcher in Germany, he joined the Theory Division in Los Alamos in 1977. In 1984 he joined the University of Washington, where he is Professor of Physics and Adjunct Professor of Astronomy. In 1990, with Ernest Henley, he helped found the Institute for Nuclear Theory, a Department of Energy visitor center. He has been the Institute’s director since 1991. Haxton chaired the APS Division of Astrophysics in 1997 and the Division of Nuclear Physics in 1993, served as Councillor-at-large during the years 1991-95, and chaired the Nominations Committee in 1997-98. He was elected to the National Academy of Sciences in 1999. He was awarded the APS Prize in 2004 for contributions to neutrino astrophysics. He currently serves on the National Academy’s Board on Physics and Astronomy. Haxton’s research focuses on theoretical aspects of neutrino and , low-energy tests of symmetries and conservation laws, and many-body techniques. His work includes the description of nuclear reactions in the high-temperature plasmas found in stellar cores and supernovae; the detection of astrophysical neutrinos and their impor- tance as a probe of neutrino mass and mixing; tests of CP violation and hadronic parity violation through atomic electric dipole and anapole moment measurements; modeling the core-collapse super- nova mechanism; and the adaptation of effective field theory methods for the solution of nonrelativistic many-body problems. He has dabbled, somewhat unsuccessfully, in the area of deep underground science facilities, discovering in the process that experimental physics is more complicated than theory.

CHERRY A. MURRAY Lawrence Livermore National Laboratory

Murray has been Deputy Director for Science and Technology at Lawrence Livermore National Laboratory since December, 2004, leading the Laboratory’s science and tech- nology activities. She received her PhD in physics in 1978 from the Massachusetts Institute of Technology. Formerly Senior Vice President for Physical Sciences and Wireless Research at , Lucent Technologies, she first joined Bell Labs in 1978 as a member of the technical staff. She held a number of management positions over the years, includ- ing department head for low temperature physics, department head for condensed matter physics, department head for semiconductor physics and director of Bell Lab’s physical research lab. In 2000, Murray became vice president for physical sciences and then senior vice president in 2001. Murray is an experimental condensed matter physicist who has worked in surface and low temperature physics, light scattering and phase transitions in complex fluids. Discover Magazine named her one of the “50 Most Important Women in Science” in 2002. She served on the APS Executive Board and Council from 2001-2004, and has been an active member of many APS taskforces, divisions and forums. In 1989, she won the APS Maria Goeppert-Mayer Award, and in 2005, the APS George E. Pake Prize.
