  • Brief Bio

    Padi is the Hubble Space Telescope Deputy Project Scientist for Operations and the Associate Chief of the Astroparticle Physics Laboratory. She has been at NASA's Goddard Space Flight Center since 1993, when she was a USRA visiting scientist with the High Speed Photometer and Polarimeter Team aboard the Hubble Space Telescope, studying the optical and ultraviolet polarization seen in X-ray binaries, pulsars and active galaxies. In 1995 she joined the Monitoring X-ray Experiment (MOXE) team, an X-ray all-sky monitor that was in development and testing as part of the Russian-led Spectrum X-Gamma mission. In 1997 she joined the Rossi X-ray Timing Experiment (RXTE) Guest Observer Facility (GOF), performing science support for the mission when not pursuin her own research on the long-term X-ray variability of X-ray binaries. From 2003 to 2008 she managed the RXTE GOF as well as the Swift Science Center.

    She spent two years on a detail at NASA Headquarters in Washington as the program scientist for the Kepler mission, the US point of contact for the MOST US Guest Observer program and as a discipline scientist for X-ray and gamma-ray astronomy. She was also the Program Officer for the Origins of Solar Systems Exoplanets program.

    Research Interests

    Long-term variability in X-ray binaries and accretion disk dynamics.

    Multiwavelength studies of the flux and spectral variability of binaries harboring a compact object, on timescales much longer than the orbital period. Application of nonlinear time series analysis methods to X-ray light curves to uncover the drivers of accretion disk dynamics, and/or accretion rate changes.

    Current Projects

    Anomalous low states in X-ray binaries and their effects on long-term cycles (LMC X-3, Her X-1).

    Characterization of non-periodic long-term cycles through novel time series analysis techniques (Cyg X-2, Cyg X-3, LMC X-3, SMC X-1, X1705-440).

    Swift survey of the Kepler field of view to detect previously unidentified CVs, X-ray binaries and active stars.

    X-ray spectral analysis of the transient Be/X-ray binary pulsar Swift J1626-5156.
