    After a short post-doctoral position at MIT (1993-1994), Dr. Szabo accepted a National Research Council (NRC) Research Associate position at the NASA/Goddard Space Flight Center (1994-1996). After the conclusion of the NRC fellowship, Dr. Szabo became a Hughes STX principal scientist contracted to GSFC until February 1998 when he was appointed a NASA civil service astrophysicist at the GSFC. Dr. Szabo is a member of the American Geophysical Union and has refereed for several journals. He has authored or co-authored over 90 scientific papers.
    Dr. Szabo specializes in heliospheric and magnetospheric shocks and discontinuities. His work includes the extension of the MHD "Rankine-Hugoniot" shock jump condition fitting technique. He has extensively analyzed the Earth, Uranus, and Neptune bow shocks. Dr. Szabo has also investigated the structure of the heliospheric current sheet and its evolution from the Sun. Recently, he has also investigated some aspects of interplanetary magnetic clouds and medium scale (10 days - 10 years) variations of magnetofluid parameters in the interplanetary medium. He has extensive experience analyzing and interpreting plasma and magnetic field data from the Voyagers, IMP 8, and WIND spacecraft. He is the data manager for the magnetic field investigation of WIND, serves as the Living With a Star Sentinels Study Scientist and leads the distributed data environment Virtual Heliospheric Observatory consortium.

    Brief Bio

    After a short post-doctoral position at MIT (1993-1994), Dr. Szabo accepted a National Research Council (NRC) Research Associate position at the NASA/Goddard Space Flight Center (1994-1996). After the conclusion of the NRC fellowship, Dr. Szabo became a Hughes STX principal scientist contracted to GSFC until February 1998 when he was appointed a NASA civil service astrophysicist at the GSFC. Dr. Szabo is a member of the American Geophysical Union and has refereed for several journals. He has authored or co-authored over 90 scientific papers.
    Dr. Szabo specializes in heliospheric and magnetospheric shocks and discontinuities. His work includes the extension of the MHD "Rankine-Hugoniot" shock jump condition fitting technique. He has extensively analyzed the Earth, Uranus, and Neptune bow shocks. Dr. Szabo has also investigated the structure of the heliospheric current sheet and its evolution from the Sun. Recently, he has also investigated some aspects of interplanetary magnetic clouds and medium scale (10 days - 10 years) variations of magnetofluid parameters in the interplanetary medium. He has extensive experience analyzing and interpreting plasma and magnetic field data from the Voyagers, IMP 8, and WIND spacecraft. He is the data manager for the magnetic field investigation of WIND, serves as the Living With a Star Sentinels Study Scientist and leads the distributed data environment Virtual Heliospheric Observatory consortium.
