The Interstellar Medium* Group at the Space Telescope Science Institute (STScI) is a collaboration between STScI research staff, associated external collaborators, and the students and postdocs with whom they work. We meet weekly, pool resources and expertise, and collaborate on research projects. We focus on interstellar, circumstellar, and circumgalactic media, mainly in nearby galaxies. But our interests are diverse and we often use stars and stellar populations in our analyses; hence the *. 

The overall focus of the ISM*@ST group is the study of nearby galaxies (including the Milky Way) as laboratories for the physical processes of the ISM, star formation, stellar feedback, and galaxy evolution. We are broad in our approach: we use wavelengths from radio to ultraviolet, spectroscopy and imaging, bayesian inference and deep learning, targeted observations and archival studies.
