    Dr. Benna is a planetary scientist with a research emphasis in plasma physics and planetary magnetospheres dynamics. Dr. Benna received his degree in Electrical Engineering from the Engineering School of Tunis (ENIT) in 1999. After obtaining a M.Sc. in Radio-wave Telecommunication from the University of Tunis in 2000, he received in 2002 a Ph.D. in Space Science from the University of Toulouse in France. From 2002 to 2003, Dr. Benna was an associate scientist at the Planetary and Terrestrial Geophysics Laboratory (CNRS) in France, and from 2003 to 2006, he was an NRC postdoctoral fellow at NASA's Goddard Space Flight Center.

    Dr. Benna’s main research interest is the numerical modeling of planetary magnetospheres and exospheres. Besides his scientific work, he uses his engineering experience to support the development of several space-borne instruments (ROSETTA-CONSERT, CONTOUR-NGIMS MSL-SAM, LADEE-NMS, and MAVEN-NGIMS). His publications include papers on MHD modeling of planetary magnetospheres, comets and icy moons of the solar system, radiotomography techniques, and ill-posed inverse problems.

    Brief Bio

    Dr. Benna is a planetary scientist with a research emphasis in plasma physics and planetary magnetospheres dynamics. Dr. Benna received his degree in Electrical Engineering from the Engineering School of Tunis (ENIT) in 1999. After obtaining a M.Sc. in Radio-wave Telecommunication from the University of Tunis in 2000, he received in 2002 a Ph.D. in Space Science from the University of Toulouse in France. From 2002 to 2003, Dr. Benna was an associate scientist at the Planetary and Terrestrial Geophysics Laboratory (CNRS) in France, and from 2003 to 2006, he was an NRC postdoctoral fellow at NASA's Goddard Space Flight Center.

    Dr. Benna’s main research interest is the numerical modeling of planetary magnetospheres and exospheres. Besides his scientific work, he uses his engineering experience to support the development of several space-borne instruments (ROSETTA-CONSERT, CONTOUR-NGIMS MSL-SAM, LADEE-NMS, and MAVEN-NGIMS). His publications include papers on MHD modeling of planetary magnetospheres, comets and icy moons of the solar system, radiotomography techniques, and ill-posed inverse problems.
