Position: Professor Office: Duane C-332 Phone: (303) 492-7669 FAX: (303) 492-7178 Email: tsnow@casa.colorado.edu

Teaching Interests:

• ASTR 1040-010 Accelerated Astronomy 2 (Spring 2003)
• Emphasis on undergraduate courses, ranging from introductory level general astronomy to upper-division astrophysics.
• Development of multimedia and Internet applications for teaching, including in-class presentations and WWW resources.
• Writing of textbooks for physical sciences, especially introductory astronomy. New book coming out in january, 1997: Universe: Origin and Evolution, by Snow and Brownsberger (Wadsworth)

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.
