HST image from PHAT of cluster, association, and galaxy


My name is Cliff Johnson and I am a Research Assistant Professor at Northwestern University in CIERA and the Dept. of Physics and Astronomy, and the Co-Director & Science Lead of the Zooniverse at the Adler Planetarium.

My current research focuses on understanding star formation behavior at spatial scales ranging from that of galaxies down to individual star-forming complexes through the combined study of stellar populations and the interstellar medium. Specifically, I study the formation and evolution of star cluster populations and young pre-main sequence star populations in the Local Group, focusing on how star and cluster formation processes depend on galactic environment. Citizen science and crowdsourcing are important tools in my research.
