CLASS is a team effort. Undergraduates, PhD students, postdoctoral researchers (“postdocs”), professors, professional research scientists, and engineers all make key contributions to the project. The team is responsible for building the telescopes and high desert site, operating the telescopes, and analyzing the data for cosmology.

CLASS is led from Johns Hopkins University in collaboration with NASA Goddard Space Flight Center, NIST Boulder, and other universities in the United States, Canada, and Chile. On this page, we list the people who have helped make CLASS happen, both now and in the past.
