About Me
I am an NSF Graduate Research Fellow in the Astronomy department at UC Berkeley.
I study the formation and evolution of galaxies by tracing the
metal content of massive quiescent galaxies over cosmic time. My primary research
advisor is Prof. Mariska Kriek.
I received my B.S. in Physics and Astrophysics from the University of Minnesota in 2019.
During my time in undergrad, I worked with Claudia Scarlata
and Gabe Brammer on the spatial
distribution of star formation in the WISP and 3D-HST surveys.
Outside of astronomy, I enjoy competeing in Strongman (see picture), knitting,
being in the outdoors, and eating lots of Thai food!

Elemental Abundances and Ages of z ~ 0.7 Quiescent Galaxies on the Mass-Size Plane:
Implication for Chemical Enrichment and Star-Formation Quenching
In this Letter we derive the elemental abundances and ages of 65 quiescent galaxies
at z ~ 0.7 from the LEGA-C survey. We find that (a) at z ~ 0.7, more compact
galaxies are more metal rich, and (b) the metallicity of the quiescent galaxy
population evolves significantly between z ~ 0.7 and z ~ 0. These results
have implications for the chemical enrichment histories and star-formation quenching
of galaxies in the early universe. Namely, (a) the mass-metallicity relation is
driven by a galaxy's ability to retain its metal-rich gas, and (b) progenitor
bias combined with quenching via gas ejection, is key to explaining the observed
metallicity evolution.
