I am a postdoctoral scholar at the University of Chicago, where I hold a Grainger Fellowship in Experimental Physics and a Kavli Institute for Cosmological Physics (KICP) Fellowship.  My work focuses on developing instruments and experimental techniques to make precision measurements of faint, diffuse radiation from the early Universe. 

With the BICEP/Keck Array series of Cosmic Microwave Background (CMB) polarization experiments located at the Amundsen-Scott South Pole Station, I work on understanding how instrumental systematics affect nanoKelvin-precision CMB polarization maps at the degree angular scales where a B-mode signature of inflationary gravitational waves might exist. 

I also work on development of a kinetic inductance detector-based millimeter-wave on-chip spectrometer.  SuperSpec will enable observations in the 200-300 GHz band with moderate spectral resolution without using a bulky grating or Fourier Transform Spectrometer.  In an initial deployment to the Large Millimeter Telescope we will demonstrate on-sky performance by measuring spectra of high-redshift dusty star-forming galaxies.  Eventually we plan to use SuperSpec in a line intensity mapping experiment to measure the ionized carbon ([CII]) power spectrum during the Epoch of Reionization.

In 2017 I completed my Ph.D. in the Harvard CMB Lab advised by John Kovac, and before that I was an undergraduate at Caltech.
