Biography

Dr. King is an experimentalist interested in studying electric space propulsion systems, including Hall-effect thrusters, ion engines, and arcjets. By utilizing strong electromagnetic forces to accelerate an ionized plasma propellant, electric thrusters take advantage of on-orbit solar power generation to enjoy significant fuel savings over traditional chemical rockets. King's research experience in the broader field of plasma physics includes such diverse subjects as the design of the in-situ electrostatic probes, ion-energy analysis and time-of-flight mass spectrometry, Doppler laser cooling of trapped ions, optical flow diagnostics, and antimatter confinement.
