My research generally focuses on observations of transiting exoplanets, ranging from hot Jupiters to temperate terrestrial planets. I use both ground-based and space-based telescopes to understand the chemistry, dynamics, and habitability of these extrasolar worlds. I received my PhD from University of Chicago in 2021, where my dissertation focused on observations and modeling of highly irradiated exoplanets. I was a NASA Sagan Postdoctoral Fellow at University of Arizona from 2021-2024 and a 51 Pegasi b Fellow at Arizona State University from 2024-2025.
