Marc Kamionkowski

Marc Kamionkowski, the William R. Kenan, Jr. Professor of Physics and Astronomy at Johns Hopkins University, is a theoretical physicist who specializes in cosmology and particle physics. He has worked on a broad range of topics, but is perhaps best known for work on dark matter, cosmological-parameter determination with the cosmic microwave background, and the polarization of the cosmic microwave background. He is also known for more recent work on the possibility that dark matter could be made of primordial black holes, and the notion that the Hubble tension might be resolved by new early-Universe physics. Before joining Johns Hopkins, he was on the faculty at Columbia University and the California Institute of Technology (Caltech). He did undergraduate work at Washington University in St. Louis, earned a Ph.D. from the University of Chicago, and was a postdoc at the Institute for Advanced Study. Kamionkowski is the Editor-in-Chief and Astrophysics and Cosmology Editor of Physics Reports. His contributions have been recognized by an array of awards, including the Department of Energy E. O. Lawrence Award, the American Astronomical Society/American Institute of Physics Dannie Heineman Prize for Astrophysics, and the Gruber Cosmology Prize.
