I am a Center for Particle Cosmology Fellow and previously a NSF Astronomy & Astrophysics Postdoctoral Fellow at the University of Pennsylvania. My research aims to build our understanding of dark matter and the early Universe by studying Galactic dynamics and ancient stars. Specifically, I am interested in characterizing the inner regions of the Milky Way, dwarf galaxies, and their oldest stars.
CV Publications (Link to ADS)These are the main tools I use to constrain the early Universe.
I use stellar spectroscopy to study nucleosynthesis in the early universe by measuring the chemical composition of ancient stars.
Galactic dynamics is a key tool for testing theories of dark matter. I am specifically interested in the Galactic bar's and inner halo's sensitivity to dark matter models.
My research relies heavily on large astronomy surveys (e.g., Gaia, SDSS, Rubin, and Roman) and I frequently use machine learning techniques to push the frontier of what these data can do.

In addition to the acitivities listed below, I love mentoring students in research and giving public talks. During grad school, I helped organize the Astronomy on Tap event in Austin and now love to speak at other chapter's events.
I co-teach an introductory undergratuate-level astronomy class at New Jersey prisons.
My work on Carbon-Enhanced Metal-Poor stars was featured in this WIRED article about Gaia DR3.
My dissertation was summarized for the public in this Forbes article.
