L. Clifton Johnson

L. Clifton Johnson is a Research Assistant Professor at Northwestern University's Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) and Department of Physics and Astronomy. His research analyzes star formation across spatial scales from galaxies to individual stellar complexes.

He specializes in combining Hubble Space Telescope optical data with ALMA sub-mm observations to study star clusters and pre-main-sequence stars in nearby galaxies including Andromeda and the Magellanic Clouds. His work examines how galactic environments influence star formation processes.

Dr. Johnson pioneers citizen science collaborations through Zooniverse, developing public participation in astronomical research. He leads imaging projects like the Panchromatic Hubble Andromeda Treasury (PHAT) survey.
