Postdoctoral Scholar in Physics

The experimental cosmology group at Caltech ( is offering a postdoctoral position in Cosmic Microwave Background studies. The group, led by Professor Jamie Bock, is currently developing the BICEP Array experiment, a series of 4 microwave telescopes optimized for sensitive measurements of degree-scale polarization, aimed at the detection of B-mode polarization signal from inflationary gravitational waves. The qualified applicant will participate in the analysis of current data from multiple receiver-year observations obtained at the South Pole with the highly-successful predecessors of BICEP Array: BICEP2, Keck Array, and BICEP3. In addition, the applicant may develop new detector arrays for expanded frequency coverage for coming seasons, and technology for larger focal plane arrays for new experiments under development, including balloon- and space-based. Depending on skills and scientific interest, candidates may participate in the development of TIME, a [CII] tomography experiment designed to probe the epoch of reionization, and possibly of SPHEREx (, a near-infrared NASA Medium Explorer mission currently in Phase A.
