Professor Halverson works in experimental cosmology, including observations of the Cosmic Microwave Background (CMB) and mm-wave instrumentation development efforts. His previous experience at Caltech, Chicago, and Berkeley has been in mm-wave studies of the CMB, including measurements of CMB temperature and polarization anisotropy with DASI (Degree Angular Scale Interferometer), and development of the APEX-SZ galaxy cluster survey instrument. His current interests include Sunyaev-Zel'dovich effect galaxy cluster surveys and fine scale CMB anisotropy measurements using the 12m APEX telescope (Chile/Atacama) and the 10m South Pole mm-wave Telescope.
