assistant professor at the Catholic University of America. Her primary interest is in the magnetic structure and dynamic evolution of coronal mass ejections (CMEs), and she uses theoretical CME models to explain a wide variety of space- and ground-based observations of CMEs from pre-eruption, through initiation and eruption, to their post-eruption state. A particular focus is observations and models of coronal prominence cavities, which represent dynamic equilibrium states that store magnetic energy, and Dr. Gibson leads an ISSI international working group to study coronal cavities. She is also a leader of the Whole Sun Month and Whole Heliosphere Interval international coordinated observing and modeling efforts to characterize the three-dimensional, interconnected solar-heliospheric-planetary system. Dr. Gibson was the recipient of the AAS-SPD 2005 Karen Harvey Prize. She obtained her Ph.D. in astrophysics from the University of Colorado, Boulder. She is a scientific editor for the Astrophysical Journal and serves on the Heliophysics Subcommittee of the NASA Advisory Council, on the AURA Solar Observatory Council, and as a member of the ATST Science Working Group. She has served on the NRC’s Committee on Solar and Space Physics, the Committee on Distributed Arrays of Small Instruments for Research and Monitoring in Solar-Terrestrial Physics: A Workshop, and the Astro2010 Panel on Radio, Millimeter, and Submillimeter from the Ground.
MICHAEL HESSE is an astrophysicist and director of the Heliophysics Science Division at NASA GSFC. Dr. Hesse has also served as director of the Community Coordinated Modeling Center at the Laboratory for Solar and Space Physics, as acting branch head for the Geospace Physics Branch, and as the project scientist for theory and modeling for NASA’s Living With a Star Program. Prior to his work at GSFC, Dr. Hesse was a principal scientist at Hughes System Corporation and a postdoctoral researcher at Los Alamos National Laboratory (LANL). His professional interests include research into fundamental physical processes in space plasmas, particularly studies of magnetospheric, solar physical, and astrophysical problems. He has been a recipient of a NASA Group Achievement Award for the Community Coordinated Modeling Center and of eleven GSFC performance awards. He was a participant in the NASA Sun-Earth Connection Roadmap. Dr. Hesse earned his Ph.D. in theoretical physics from Ruhr University, Bochum, Germany. He served on the NRC Panel on Solar Wind and Magnetospheric Interactions for the 2003 decadal survey.
J. TODD HOEKSEMA is a senior research scientist in the W.W. Hansen Experimental Physics Laboratory at Stanford University. His professional experience includes research administration, system and scientific programming, and the design, construction, and operation of instruments to measure solar magnetic and velocity fields from both the ground and space. He is co-investigator and magnetic team lead for the Helioseismic and Magnetic Imager on NASA’s Solar Dynamics Observatory (SDO) and the instrument scientist for the Michelson Doppler Imager instrument on the Solar and Heliospheric Observatory that was launched by NASA and the European Space Agency (ESA). He has been associated with the Wilcox Solar Observatory at Stanford for three sunspot cycles. His primary scientific interests include the physics of the Sun and the interplanetary medium, solar-terrestrial relations, the large-scale solar and coronal magnetic fields, solar velocity fields and rotation, helioseismology, and education and public outreach. Dr. Hoeksema was chair of the Solar Physics Division of the American Astronomical Society (AAS) and has served on the heliophysics subcommittee of the NASA Advisory Council Science Committee. He served for 4 years as a solar physics discipline scientist at NASA. Dr. Hoeksema led NASA’s 2005 Heliophysics Roadmap Team. He has been awarded the NASA distinguished public service medal and is a member of the AAS, AGU, International Astronomical Union (IAU), American Scientific Affiliation, and AAAS. He earned his Ph.D. in applied physics from Stanford University. For several years, Dr. Hoeksema was the vice chair of Commission E.2 of the Committee on Space Research. He served on the NRC’s Astro2010 Panel on Optical and Infrared Astronomy from the Ground.
