Marc Kamionkowski (born 1965)[1] is an American theoretical physicist and currently the William R. Kenan, Jr.
Professor of Physics and Astronomy at Johns Hopkins University.
His research interests include particle physics, dark matter, inflation, the cosmic microwave background and gravitational waves.
[2] He is known primarily for work on supersymmetric dark matter and the cosmic microwave background.
He was awarded the US Department of Energy's 2006 E. O. Lawrence Award in High Energy and Nuclear Physics for "his theoretical analyses demonstrating that precise observations of the cosmic microwave background can lead to deep understanding of the origin and evolution of the Universe, thereby motivating a series of increasingly precise cosmological experiments".
