I went to undergrad at Carnegie Mellon University, intending to double major in physics and philosophy, I eventually got too hooked on math and switched to physics and mathematics, specializing in astrophysics.

Inspired by my undergrad research in Galactic Dynamics with Dr. Matthew Walker and my summer research experience for undergraduates (REU) in Cosmology with Dr. Lloyd Knox, I applied to graduate school in astrophysics. Before I started the PhD program in the Princeton Astrophysics Department, I completed Part III of the Mathematical Tripos at the Institute of Astronomy (IoA) at Cambridge University in England. While in Cambridge I did research with Dr. Vasily Belokurov and Dr. Wyn Evans on the structure of the Milky Way’s Stellar Halo.

Early in my PhD at Princeton I worked on a large variety of topics in Astrophysics. My work under Dr. David Spergel caused me to travel often to the Center for Computational Astrophysics (CCA) (where I now work) and where I collaborated with many other researchers. I also worked closely with Dr. Jenny Greene on observational projects related to Intermediate Mass Black Holes.

In 2019 I started my thesis work with Dr. Eve Ostriker, though I also worked closely with Dr. Chang-Goo Kim and Dr. Jeong-Gyu Kim. The main guiding goal of my thesis was to try to understand the magneto-hydrodynamic (MHD), stellar dynamic, and feedback processes involved in star formation in dense environments. I am particularly interested in the outstanding problem of Multiple Populations in Globular Star Clusters, and how feedback from forming stars can act to chemically enrich gas that subsequently forms more stars, creating chemically distinct but co-natal populations. In order to tackle this larger goal, I have found that we must first form a much better understanding of how winds from massive stars interact with the dense environments in which these stars form.

As a Junior Fellow in the Simons Society of Fellows from 2022-2025 I continued work on understanding the dynamics of WBBs in the presence of background magnetic fields and the co-evolution of stellar winds with the gas that is photo-ionized by massive stars in star-forming regions.

My recent and ongoing work focuses on how we can use the intricate understanding of the dynamics of star-forming regions that I have developed to make predictions for the observed properties of these regions from current and upcoming observational facilities, such as the James Webb Space Telescope (JWST), the Chandra X-ray Observatory, and large spectroscopic surveys of gas in nearby galaxies such as the Local Volume Mapper (LVM) and PHANGS-MUSE.
