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 research in experimental cosmology focuses on understanding the physics of the very early Universe and constraining potential extensions to the \(\Lambda CDM\) cosmological model.  Much of this work involves developing novel millimeter-wave instruments to measure faint, diffuse backgrounds from early times: the cosmic microwave background (CMB) and the integrated emission of high-redshift galaxies (line intensity mapping).  Projects that I work on include:

  • South Pole Observatory: a collaboration between BICEP/Keck Array and the South Pole Telescope CMB experiments
  • CMB-S4: the next-generation CMB experiment
  • SuperSpec: a millimeter-wave on-chip spectrometer for line intensity mapping and surveys of high-redshift galaxies

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.
