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. He has been serving as the chief of the Heliospheric Physics Laboratory since 2010. Dr. Szabo is a member of the American Geophysical Union and has refereed for several journals. He has authored or co-authored over 120 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, Parker Solar Probe, DSCOVR, and WIND spacecraft. He is the NASA mission scientist for the Parker Solar Probe and HelioSwarm, and project scientist for the DSCOVR mission.
