About





I am a PhD student at the University of Chicago working with Professor Daniel Holz, and I am a member of the LIGO-Virgo-KAGRA Scientific Collaboration. I am a NSF Graduate Research Fellow and a William Rainey Harper Fellow.


I am interested in using populations of gravitational wave sources to learn about the Universe. Looking at each gravitational wave detection as part of a larger collection reveals insights about compact object formation, binary stellar evolution, the expansion of the Universe, gravitational lensing, and more. Inferring this population from gravitational-wave data lets us extract this information for ourselves.


In my free time, I like to hike, take care of plants, and spend time by Lake Michigan.
