Dr. Moore is the Head of the Interplanetary Physics Branch in the Laboratory for Extraterrestrial Physics at NASA's Goddard Space Flight Center. His principal interests are in the heating and acceleration of ionospheric plasmas, their escape into space to form planetary plasmaspheres, and in the further acceleration of these plasmas to form unstable plasma sheets and diamagnetically-trapped ring currents. He has also conducted active space plasma experiments to explore plasma heating phenomena. Dr. Moore is the lead investigator for the IMAGE LENA instrument and has been involved as a science investigator or project scientist in investigations on a number of NASA suborbital, space shuttle, and orbital missions, including the Retarding Ion Mass Spectrometer (RIMS) experiment on Dynamics Explorer-1 and the Thermal Ion Dynamics Experiment and Plasma Source Instrument on Polar. Dr. Moore has served on numerous committees and study teams, including the NRC Space Studies Board Committee on Solar and Space Physics, the NASA Sun-Earth Connection Advisory Subcommittee, and the NASA study teams for the Solar Probe and Inner Magnetosphere Imager missions.
