About Me

I’m a second-year Ph.D. student in the UChicago Department of Astronomy & Astrophysics. My research is in observational cosmology: I am currently working on measuring the Hubble constant to high precision and accuracy using the Tip of the Red Giant (TRGB) and newly-developed J-region Asymptotic Giant Branch methods. My advisor is Wendy Freedman.

I was an undergrad at Penn, where I worked with Gary Bernstein. I graduated with a B.A. in Physics in 2019.
