I explore the intricate relationship between the interstellar medium, star formation, and feedback and its role in how galaxies evolve.

My research links the properties of the interstellar medium (ISM) from large scales measured in extragalactic sources to the small scales observed within the Milky Way. Linking large and small ISM scales offers insight into many key open questions about the role of the ISM and star formation in galaxy evolution, including: How is interstellar turbulence driven? How do molecular clouds form? What role does the atomic ISM play in the evolution of molecular clouds?
