Attila Komjathy

Attila Komjathy is a Principal Investigator and a Senior Research Staff of the Ionospheric and Atmospheric Remote Sensing (IARS) Group of the Tracking Systems and Applications Section at NASA's Jet Propulsion Laboratory (JPL), the California Institute of Technology, specializing in various aspects of ionospheric and atmospheric remote sensing techniques. He received his Ph.D. from the Department of Geodesy and Geomatics Engineering of the University of New Brunswick, Canada. He spent four years as a postdoctoral researcher at the University of Colorado at Boulder. He has been with JPL since 2001. He is recipient of the Canadian Governor General's Gold Medal for Academic Excellence, several NASA awards including an Exceptional Space Act Award, Best Paper Awards, numerous JPL Group Achievement Awards, and a United States Patent in Oct 1997. He was honored with the recognition “50+ Leaders to Watch” by GPS World Magazine in May 2008. He is a member of the WAAS Integrity Performance Panel (WIPP). He is also Editorial Board member of the Journal GPS Solutions and AGU’s Radio Science.
