    As the Center of Excellence in the Physics of the Heliosphere and the Sun (CEPHEUS) Deputy Director, Dr. Guidoni sustains and enhances the educational program associated with The Catholic University’s on-going collaboration with the Heliophys Science Division at NASA Goddard Space Flight Center.

    Dr. Guidoni is a heliophysicist who focuses on the study of solar eruptions. In particular, she is interested in magnetic reconnection and physical processes of reconnected plasma. At NASA Goddard Space Flight Center, she runs and analyzes simulations of solar eruptions using the Adaptively Refined Magnetohydrodynamics Solver code, a state-of-the-art, parallelized, computer program. She is currently a Pricipal Investigator on a grant for computer time at the NASA High End Computing systems.

    Dr. Guidoni has also experience analyzing data from several NASA missions. She has studied and modeled solar flares and related transient activity using data from the Solar Dynamics Observatory (SDO), Solar TErrestrial RElations Observatory (STEREO), and Hinode missions.

    Dr. Guidoni is very active in the Heliophysics community, she has served as a member of NASA panels, as a peer-reviewer for The Astrophysical Journal, the Astrophysical Journal Letters, and the Solar Physics journal, and as a judge for the Outstanding Student Paper Awards for the American Geophysical Union and the Solar Physics Division Student Poster Award. She is a science consultant for a high school in Argentina and a session organizer for the National Solar Heliospheric and INterplanetary Environment (SHINE) Conference.
