Current Position

I am a NPP Fellow at NASA GSFC. My research mentor at Goddard is Dr. Mark Clampin, JWST Observatory Project Scientist.

Research Interests

Circumstellar Disks: I use multi-wavelength observational techniques to investigate the structure, evolution, and origin of a wide variety of circumstellar disks and envelopes.

    High Contrast Imaging of Protoplanetary and Debris Disks: I use a variety of ground- and space-based facilities to spatially resolve protoplanetary and debris disks. Identifying and characterizing morphological features and colors of these disks provides insight into the formation and early evolution of extra-solar planetary systems.

    Circumstellar Environments of MS and Post-MS stars: I also study the disks, winds, and ejecta of massive main- and post-main-sequence OB stars. My work currently focuses on assessing how rapid rotation and other environmental factors, such as metallicity, influence the evolution of massive stars and their circumstellar environments.

Extrasolar Planets: I am currently engaged in projects which use transit photometry and high-precision astrometry as means to detect new extrasolar planetary systems.
