My name is Cliff Johnson and I am a CIERA postdoctoral fellow at Northwestern University.

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.

I currently collaborate as a member of three survey teams: the SMIDGE survey, analyzing Hubble Space Telescope imaging of the Small Magellanic Cloud; the SMASH survey, analysing DECam imaging of the Large and Small Magellanic Clouds; and the PHAT-M33 survey, analysing Hubble Space Telescope imaging of the Triangulum Galaxy.

I completed my PhD at the University of Washington under the co-supervision of Julianne Dalcanton and Anil Seth. I analyzed the star cluster population of M31 as part of the Panchromatic Hubble Andromeda Treasury (PHAT) survey.
