Marc Kamionkowski

Marc Kamionkowski is the William R. Kenan, Jr. Professor in the Department of Physics & Astronomy at Johns Hopkins University, part of the Krieger School of Arts & Sciences. He holds a BA from Washington University (1987) and a PhD from the University of Chicago (1991). His career includes roles at Columbia University, Caltech (as Robinson Professor of Theoretical Physics and Astrophysics), and has been at Johns Hopkins since 2011. His research focuses on theoretical cosmology and particle physics, particularly dark matter, cosmic microwave background, and gravitational waves.

Key research areas include particle dark matter, inflationary cosmology, cosmic acceleration, neutrino physics, and large-scale structure. He has contributed to understanding dark matter halos, early universe phase transitions, and gravitational wave detection methods. His work bridges particle physics and astrophysical observations, addressing cosmological tensions like the Hubble constant discrepancy.

Publications span gravitational wave backgrounds, 21-cm signal modeling, neutrino mass constraints, and early dark energy theories. He collaborates on projects like line-intensity mapping and pulsar timing arrays, advancing observational cosmology techniques.

He has advised numerous graduate students and researchers, though specific names are not listed here. His research is supported by grants exploring cosmic microwave background analysis, dark matter detection, and gravitational wave astrophysics. Kamionkowski’s work also interfaces with upcoming facilities like LISA and next-generation ground-based observatories.
