My interests center around the nature of
interstellar, circumstellar, and interplanetary
dust grains, and the role they play in the formation of planetary systems. In
the past few years I have been investigating the emission characteristics of
the grains in the dusty disks surrounding young stars, and how they are
evolving as the stellar systems age. The particle sizes and compositions are
being compared to those of the diffuse interstellar medium, cometary grains of our own solar system, and dust grains
condensed in the laboratory. Most of my recent observational work has been
carried out with the Broadband Array Spectrograph System (BASS) of The
Aerospace Corporation on the NASA Infrared Telescope Facility.
