David Galvan is an Associate Physical Scientist with expertise in space science and engineering, remote sensing, quantitative data analysis, modeling and simulation. His policy research interests include space, transportation, the environment, energy, and defense. Since joining RAND in 2012, he has contributed to research efforts on a variety of topics including satellite anomalies, implications of disaggregated architectures on the space launch enterprise, dependence of U.S. launch vehicles on foreign components, alternative fuel vehicles, traveling ionospheric disturbances, and modeling and simulation of air-to-air combat.
Before joining RAND, Galvan was a Caltech Postdoctoral Scholar at NASA Jet Propulsion Laboratory (2009-2012). He used ground-based GPS receivers to study ionospheric disturbances caused by tsunamis.
Galvan earned his Ph.D. (2009) and M.S. (2005) in Geophysics and Space Physics from UCLA. He explored the dynamics and density structure of the plasmasphere, a population of cold plasma in Earth's inner magnetosphere, using remote sensing techniques such as extreme ultraviolet (EUV) imaging and total electron content (TEC) measurements from GPS receivers onboard LEO satellites. He also repaired and deployed geophysical magnetometers in Antarctica and Puerto Rico.
Galvan earned his B.S. (2003) from UC San Diego, majoring in Physics with a minor in Space Science and Engineering. While an undergraduate, he served as a co-op at NASA Johnson Space Center, a summer intern at NASA Ames Research Center, and an intern at ISS EarthKAM, a UCSD/NASA project enabling middle school students to command an Earth-pointing camera onboard the International Space Station.
