Julia Roman-Duval

Julia Roman-Duval is tenured astronomer at STScI. Her long-term research objective is to understand the physical processes that dynamically shape the structure and properties of the interstellar medium (ISM) and how these properties influence the star formation process and the evolution of galaxies. Her focus over the last few years has been to study dust evolution in the ISM of nearby galaxies, using a multi-wavelength approach (UV to radio). Julia co-leads the ISM*@STScI working group.
