Originally from Upstate New York near the Canadian border, I am a Ph.D. candidate in the Department of Astronomy and Astrophysics at the University of Chicago. I completed my A.B. in Astrophysical Sciences with honors at Princeton University in 2023.

My research focuses on measuring stellar metallicities in the faintest dwarf galaxies, using low-to-medium resolution spectroscopic observations to understand the earliest phases of galaxy formation. I currently am advised by Prof. Alexander Ji at UChicago.

Outside of research, I love kayaking, running, and watercolor painting.
