Abby's research is focused on experimentally investigating some of the most fundamental questions about the nature of our Universe. Her research ranges from the study of the extremely early universe to probing our understanding of particle physics and astrophysics at extremely high energies.

Abby works on a series of polarimeters at the South Pole (BICEP2, The Keck Array, and BICEP3) that aim to directly probe the epoch of Inflation in the very early universe by measuring the unique polarization signature which would have been imprinted on the Cosmic Microwave Background by the Inflationary Cosmic Gravitational-Wave Background.

Abby also works on experiments that search for ultra-high energy neutrinos (E~1018 eV) using radio detection techniques. She works on ANITA, a balloon-borne telescope that was designed to search for coherent radio emission produced by the interaction of UHE neutrinos with Antarctic ice and by UHE cosmic rays that induce showers in the atmosphere. She is also working on a new detector, the Greenland Neutrino Observatory (GNO) that will look for ultra-high energy neutrinos from a ground-based array at Summit Station in Greenland.

For more about her research, see her web page.
