Hi, and welcome to my website! I'm currently a Postdoctoral Fellow at the Kavli Institute for Theoretical Physics (KITP) in Santa Barbara, CA. I was previously an NSF Graduate Fellow at University of Wisconsin - Madison, where in Summer 2020 I completed my Ph.D. on "Cosmic Ray Transport and the Galaxy Gas Cycle" with my advisor Ellen Zweibel and co-advisor Elena D'Onghia.
My research focuses on plasma astrophysics. More specifically, I explore, through both analytic studies and simulations, how galactic winds expel mass from galaxies and regulate star formation; how energetic particles called cosmic rays launch galactic outflows and shape their multiphase environments; and how cosmic ray propagation can be constrained with observations. I'm also interested in the formation and survival of cold/warm gas in hot, circumgalactic environments, with one fascinating, nearby example being the Magellanic Stream.

Within the broader fields of galaxy evolution and plasma astrophysics, my research program is defined by a few principal methodologies and topics:
Turbulence and multiphase gas in galaxy halos
Leveraging both proprietary and open-source tools to create, analyze, and visualize terabytes of simulation data
Creating mock observations to bridge gaps between theory and observations
Exploring emerging machine learning technologies to extract insights from data

Some galaxies (e.g. the M82 starburst galaxy shown in the image) can launch extended outflows of multiphase gas at speeds greater than 1000 km/s. I study how these winds are launched by supernovae and how they compare to observations. A recent focus of my work is the Magellanic system, an intriguing case-study in gas dynamics that provides a useful test-bed for models of galactic outflows.
Cosmic rays, shown in this depiction of a cosmic ray air-shower hitting the Pierre-Auger detector, are the highest energy particles in the Universe and affect a variety of astrophysical environments. I study how cosmic rays assist the launching of galactic winds, how they structure the interstellar medium, and how they are accelerated at astrophysical shocks, including shocks produced by galactic winds.
