I am a postdoctoral scholar at the University of Chicago and Fermilab, where I hold an NSF Astronomy and Astrophysics Postdoctoral Fellowship and a Schramm Fellowship in Experimental Astrophysics. 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:

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

From 2017 to 2020 I was a Grainger and KICP Fellow at the University of Chicago.  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.
