Eric Koch

I'm an astronomer researching how matter in interstellar space accumulates to form stars. I'm a Submillimeter Array (SMA) & NSERC Fellow, and the Director of Seamless Astronomy at the Center for Astrophysics | Harvard & Smithsonian.


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?

About Me

I'm from Western Canada, where I completed my BSc at UBC-Okanagan, and MSc and PhD at the University of Alberta. I started at the CfA in Fall 2020.

I enjoy hockey, hiking in the mountains, and occasionally climbing rocks.
