Research Interests

Multiwavelength Observational Astronomy

My research involves multiwavelength observations of accreting compact objects such as black holes and neutron stars. My primary interests are in applying such observations to understand the structure, physical conditions, and astrophysics of the accretion flows onto these objects in both X-ray bright phases and quiescent states. To achieve this I use a variety of space-based telescopes including the Hubble Space Telescope for ultraviolet and optical observations and the Chandra X-ray Observatory and Rossi X-ray Timing Explorer for X-ray data, and also several ground-based optical, infrared, and radio facilities. In more detail, my two most active interests are: constraining the geometry and efficiency of X-ray irradiation of accretion disks using multiwavelength spectral energy distributions and reverberation mapping; and probing the instabilities in accretion onto quiescent black holes by studying short-timescale variability and correlating variability at different wavelengths.
