Nils Halverson arrives at CU Boulder in summer 2005 as a new Assistant Professor working 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
