Research Interests:

• Observational studies of the chemistry and physics of the diffuse interstellar medium.
• Analysis of the interaction between gas and dust, as indicated by depletion studies (optical and UV) and by infrared solid-state absorption features.
• Studies of interstellar dust extinction.
• Observational and laboratory research on the diffuse interstellar bands.
• Ground-based and space-based spectroscopy, in the UV, visible, and infrared wavelength bands.
