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.
