Kevin Huffenberger works in broad areas of astrophysics and cosmology, which is the study of the large-scale universe to learn about its structure, content, origin, and evolution. In his group, the primary subject is the Cosmic Microwave Background (CMB). The afterglow of the Big Bang, the CMB is seen today in the microwave-wavelength band of the electromagnetic radiation spectrum. His group also works on topics like large-scale structure, the cosmic X-ray background, gravitational weak lensing, and mm-wave-bright galaxies and transient objects. Prof. Huffenberger works in several experimental / observational collaborations: The Atacama Cosmology Telescope, The Simons Observatory, and CMB-S4. In the past, he worked with the Planck satellite mission and the Q/U Imaging ExperimenT (QUIET). He has also worked on a number of independent projects in smaller groups, some related to the CMB and some related to other aspects of cosmology or astrophysics. His work is funded by NASA, the National Science Foundation, and the Department of Energy.
