About Me

I am an experimental physicist who develops cutting-edge instrumentation and data analysis techniques to make sensitive measurements of cosmic history.

Currently, I am a graduate student in my final year at UC Berkeley working on the South Pole Telescope (SPT), a 10-meter microwave telescope at Amundsen-Scott South Pole Station in Antarctica. During grad school I built and commissioned SPT-3G, the most recent camera on the SPT. SPT-3G makes precision measurements of the Cosmic Microwave Background, the oldest light in the universe. I am currently working on my thesis project. Using the data from SPT-3G, I am developing novel analysis techniques to measure the polarization of the CMB to search for the signature of gravitational waves imprinted during inflation.

Previous to grad school, I worked on a variety of projects pursuing my interest in high-energy astrophysics. These included doing site characterization and instrumentation for the Greenland Neutrino Observatory, an in-ice radio detector for astrophysical ultra-high energy neutrinos, and studying cosmic ray acceleration in supernova remnants with the Fermi LAT and VERITAS.

In Fall 2022, I will start as a NASA Einstein Fellow at the University of Chicago and will subsequently hold a joint appointment as a Fermilab Lederman Fellow and as a University of Chicago KICP Fellow.
