About Me

I’m a Ph.D. student in the UChicago Department of Astronomy & Astrophysics. I am an observational cosmologist. I am currently focusing on developing high-precision local distance indicators, like the JAGB method and TRGB, to measure the Hubble constant. I am also interested in using strongly lensed quasar systems to measure cosmological parameters with the TDCOSMO collaboration. I received my B.A. in physics at Penn in 2019.
