dynamic code validation and verification. She is the recipient of an NSF CAREER Award. Dr. Winebarger
received an M.S. and a Ph.D. in physics from the University of Alabama, Huntsville.
DANIEL WINTERHALTER is a principal scientist with JPL, California Institute of Technology. His research
interests include the spatial evolution of the solar wind into the outer reaches of the heliosphere, as well
as its interaction with, and influence on, planetary environments. He has published articles in refereed
journals and edited two books on this subject. Most recently he has been interested in the low-frequency
radio emissions from the (presumed) magnetospheres of extrasolar planets, for which his team has carried
out observations with the world’s largest radio telescopes. As a member of several flight teams over the
years, Dr. Winterhalter is and has been intimately involved with the planning, launching, and operating of
complex spacecraft and space science missions. He received a NASA Special Recognition Certificate for
his work on Mars Observer. Dr. Winterhalter is the experiment representative for the Mars Global Surveyor
magnetometer team, and until recently was the investigation scientist for the Cassini Radio Science Experiment. He was the study scientist for the space science Mercury Orbiter effort in 1996 and the pre-project
scientist for the Mars Science and Telecom Orbiter. Dr. Winterhalter has received achievement awards
for his participation on the Voyagers 1 and 2, Pioneer 11, and Mars Observer, Mars Global Surveyor, and
Cassini interplanetary probes. He received an M.S. and a Ph.D. in geophysics and space physics from
UCLA. Dr. Winterhalter previously served on the NRC’s NASA Technology Roadmaps: Instruments and
Computing Panel.
THOMAS N. WOODS is the associate director for Technical Divisions at LASP at the University of Colorado, Boulder. He previously held research scientist positions at LASP and HAO. His research is focused
primarily on solar ultraviolet irradiance and its effects on Earth’s atmosphere. Dr. Woods is the principal
investigator for numerous experiments, including the EUV Variability Experiment on the NASA SDO;
X-Ray Sensor and EUV Sensor on NOAA GOES-R; Solar Radiation and Climate Experiment as a mission
for NASA’s Earth Observing System; and the Solar EUV Experiment on the Thermosphere, Ionosphere,
Mesosphere Energetics and Dynamics mission. He received an M.A. and a Ph.D. in physics from Johns
Hopkins University.

ARTHUR A. CHARO, Study Director, joined the SSB as a senior program officer in 1995. He has directed
studies that have resulted in some 30 reports, notably the first NRC decadal survey in solar and space
physics (2003) and in Earth science and applications from space (2007). Dr. Charo received his Ph.D. in
physics from Duke University in 1981 and was a postdoctoral fellow in chemical physics at Harvard University from 1982 to 1985. He then pursued his interests in national security and arms control at Harvard
University’s Center for Science and International Affairs, where he was a research fellow from 1985 to
1988. From 1988 to 1995, he worked as a senior analyst and study director in the International Security
and Space Program in the U.S. Congress’s Office of Technology Assessment. Dr. Charo is a recipient of a
MacArthur Foundation Fellowship in International Security (1985-1987) and a Harvard-Sloan Foundation
Fellowship (1987-1988). He was the 1988-1989 American Institute of Physics AAAS Congressional Science
Fellow. In addition to NRC reports, he is the author of research papers in molecular spectroscopy, reports
on arms control and space policy, and the monograph “Continental Air Defense: A Neglected Dimension
of Strategic Defense” (University Press of America, 1990).
