I am a NPP Fellow at NASA GSFC. My research mentor at Goddard is Dr. Mark Clampin, JWST Observatory Project Scientist.
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
Extrasolar Planets: I am currently engaged in projects which use transit photometry and high-precision
astrometry as means to detect new extrasolar planetary systems.
