Research

Interstellar dust is ubiquitous, yet its precise composition is still widely debated. The overall goal of my research is to trace the evolution of dust as it cycles from the diffuse regions of interstellar space into cold dark clouds where grain growth and ice mantles change the nature of the dust grains. My colleagues and I accomplish this goal by studying the infrared spectra of dust in the general interstellar medium, cold dark clouds and star-forming regions. The dust that becomes part of the star-formation process will eventually be incorporated into protoplanetary disks that may resemble the beginnings of our own Solar System.
