About My Work

Pryke is an experimental cosmologist and educator. His research currently centers on the cosmic microwave background (CMB) - the after glow from early times when the Universe was a smooth hot plasma. By studying the CMB we can learn much about the origin, contents and ultimate fate of the Universe - CMB studies are at the center of the current "golden age" of cosmology.Pryke has played a leading role in the construction and operation of a series of CMB telescopes cited at the South Pole in Antarctica, and the analysis of the data they produce.He was a key member of the DASI team which produced the first detection of the polarization of the CMB.

More recently he co-led the QUaD experiment - another ground breaking CMB polarimeter.Currently he is co-leading the Keck-Array CMB polarimeter (aka SPUD) which takes sensitivity to the next level in the quest to detect gravity waves spawned by inflation in the first instant after the big bang.Pryke is also a member of the SZA and SPT collaborations which are using the CMB as a "backlight" to study the evolution of massive clusters of galaxies and learn about the mysterious dark energy which appears to pervade empty space.
