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 also 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
CATHERINE A. GRUBER, editor, joined the SSB as a senior program assistant in 1995. Ms. Gruber
first came to the NRC in 1988, as a senior secretary for the Computer Science and Telecommunications
Board and also worked as an outreach assistant for the National Science Resources Center. She was a
research assistant (chemist) in the National Institute of Mental Health's Laboratory of Cell Biology for 2
years. She has a B.A. in natural science from St. Mary's College of Maryland.
AMANDA R. THIBAULT, research associate, joined the Aeronautics and Space Engineering Board
(ASEB) in 2011. Ms. Thibault is a graduate of Creighton University, where she earned her B.S. in
atmospheric science in 2008. From there she went on to Texas Tech University, where she studied
lightning trends in tornadic and non-tornadic supercell thunderstorms and worked as a teaching and
research assistant. She participated in the Verification of the Origins of Rotation in Tornadoes
Experiment (VORTEX 2) field project from 2009 to 2010 and graduated with an M.S. in atmospheric
science from Texas Tech in August 2010. She is a member of the American Meteorological Society.
DIONNA WILLIAMS is a program associate with the SSB, having previously worked for the National
Academies' Division of Behavioral and Social Sciences and Education for 5 years. Ms. Williams has a
long career in office administration, having worked as a supervisor in a number of capacities and fields.
Ms. Williams attended the University of Colorado, Colorado Springs, and majored in psychology.
TERRI M. BAKER was a senior program assistant for the SSB until April 2012. She came to the SSB
from the National Academies' Center for Education. Mrs. Baker has held numerous managerial,
administrative, and coordinative positions and has focused on improving productivity and organization
wherever she works. Mrs. Baker is currently working on her B.A. in business management.
DANIELLE PISKORZ, an SSB Lloyd V. Berkner space policy intern, recently graduated from the
Massachusetts Institute of Technology with a degree in physics and a minor in applied international
studies. She has done various research projects at L'Institut d'Astrophysique de Paris, Los Alamos
National Laboratories, and the Jet Propulsion Laboratory and spent her junior year studying at the
University of Cambridge. Ms. Piskorz plans to begin her graduate studies in Fall 2012 in geophysics.
MICHAEL BARTON, an SSB Lloyd V. Berkner space policy intern, recently graduated from Mississippi
State University with a B.S. in aerospace engineering with a concentration in astronautics and a minor in
leadership studies. He spent last summer in the NASA Academy for Space Exploration at NASA Glenn
Research Center, where he worked on research projects in computational fluid dynamics and microgravity
test beds. As part of the NASA Academy, Mr. Barton was able to tour other NASA centers and
commercial space operations, as well as meet many engineers and managers across the workforce.
Previous to that, he was a co-op engineer in space shuttle guidance and navigation during the waning
years of the Space Shuttle Program at NASA Kennedy Space Center. These experiences have given him
insight into the culture and operational processes of NASA. At Mississippi State, Mr. Barton has served
