JACK MILLER is currently principal investigator and leader of a group at the Lawrence Berkeley National Laboratory conducting and analyzing the results of accelerator experiments with high-energy heavy ions, with an emphasis on the study of heavy-ion fragmentation and transport in matter. These studies are directed primarily toward the assessment and mitigation of risks to humans in space outside the geomagnetosphere. The experiments focus on characterizing the radiation field produced by interactions of the high-energy heavy-ion component of galactic cosmic radiation with spacecraft and planetary habitat shielding materials and biological organisms, including humans. Dr. Miller’s professional interests and experience include nuclear physics with heavy ions; sources and effects of space radiation, in particular the heavy ions in the galactic cosmic radiation; simulation of the space radiation environment at particle accelerators; and theoretical modeling of space radiation effects. He received a Ph.D. in physics from the University of California in 1987, an M.S. in physics from San Francisco State University, and a B.S. in physics at the University of Michigan.
WALTER SCHIMMERLING is the former program scientist for NASA’s Space Radiation Health Program, Bioastronautics Research Division. Dr. Schimmerling served as a research biophysicist and senior research scientist at the Lawrence Berkeley National Laboratory from 1972 to 1989. He also served as a NASA visiting senior scientist at the Jet Propulsion Laboratory, manager of the Radiation Health Program at NASA Headquarters, and program director of the joint NASA-National Cancer Institute research project on genomic instability. He is the author of numerous publications on mitigating the health effects of radiation during spaceflight. He was also the chief scientist of the Space Life Sciences Division of the Universities Space Research Association.
HOWARD J. SINGER is chief of the Science and Technology Infusion Branch at the National Oceanic and Atmospheric Administration’s (NOAA’s) Space Environment Center (SEC). In addition, he is the project scientist for the current and future NOAA Space Environment Monitor instruments on the Geostationary Operational Environmental Satellite (GOES) spacecraft and the responsible scientist for the GOES spacecraft magnetometers. Prior to joining SEC, Dr. Singer was with the Air Force Geophysics Laboratory, where he was the principal experimenter for the fluxgate magnetometer on the joint Air Force-NASA Combined Release and Radiation Effects satellite. Dr. Singer’s research is in the area of solar-terrestrial interactions, ultra-low-frequency waves, geomagnetic disturbances, storms, and substorms. He has served on various NASA, National Science Foundation (NSF), U.S. Geological Survey, and NRC committees, including recent service on the NASA Living With a Star Geospace Mission Definition Team. From 2001 to 2003 he served on the NRC Solar and Space Physics Survey Panel on Atmosphere-Ionosphere-Magnetosphere Interactions. Dr. Singer is currently on the NSF Geospace Environment Modeling Steering Committee and the Editorial Advisory Board of Space Weather: The International Journal of Research and Applications. Dr. Singer was co-editor of the 2001 AGU Geophysical Monograph, Space Weather. He has received awards from the Air Force, NASA, and NOAA, including the prestigious Department of Commerce Gold Medal for Leadership. He serves on the NRC Committee on Solar and Space Physics.
LEONARD STRACHAN is an astrophysicist at the Harvard-Smithsonian Center for Astrophysics, where he has been working since 1991. He received his Ph.D. in astronomy from Harvard University. Dr. Strachan is a member of the Ultraviolet Coronagraph Spectrometer (UVCS) team on the Solar and Heliospheric Observatory (SOHO) mission. His research focuses on developing remote sensing techniques and instrumentation for studying the solar corona and solar wind using extreme ultraviolet radiation spectroscopy. Specifically, he is interested in determining the plasma properties and large-scale characteristics of the solar wind acceleration region of the solar corona. Such measurements are important for understanding
