Profile

Jeffrey McMahon

Assistant Professor
Departments of Astronomy and Astrophysics and Physics and the College

Jeffrey McMahon studies cosmology and fundamental physics through measurements of the cosmic microwave background (CMB). He is particularly interested in using the CMB as a tool to study known mysteries including dark matter, dark energy, and inflation—the theory of our universe’s first moments; and to hunt for new surprises. He collaborates with the Atacama Cosmology Telescope, Simons Observatory, the South Pole Telescope, and CMB-S4 to pursue these research topics.

He has published more than 120 peer-reviewed research articles in such publications as The Astrophysical Journal, Applied Optics, and Astroparticle Physics.

McMahon received his PhD in physics from Princeton University and was a postdoctoral fellow in the Enrico Fermi Institute and the Kavli Institute for Cosmological Physics at the University of Chicago. Prior to joining the University of Chicago, he was an associate professor of physics at the University of Michigan, where he received the Class of 1923 Memorial Teaching Award.
