Science
I graduated from UCLA in 2022 with a B.S. in astrophysics and minor in atmospheric and oceanic sciences. After graduating, I spent two years working at Los Alamos National Laboratory (LANL) on magnetospheric research as a post-baccalaureate researcher. At LANL, my primary effort was in a comprehensive reprocessing and analysis of HOPE mass spectrometer ion measurements taken over the overarching duration of the Van Allen Probes mission, culminating in characterization of a prominent, asymmetric heavy-ion population in the near-Earth magnetosphere.
I have now begun graduate study at the University of Michigan in Ann Arbor. In the Department of Climate and Space Sciences (familiarly known as CLASP) , I will be continuing to investigate the structure and dynamics of planetary magnetospheres, working with Professor Mike Liemohn on empirical analysis and numerical modeling of the distinctive gas-giant plasma environments.
At the University of Michigan, I am a member of the MITHRAS (Magnetosphere-Ionosphere-Thermosphere Research & Applied Sciences) research group, which synergistically strives to enhance our understanding of the coupled dynamics of plasma and electromagnetic fields in various heliospheric and planetary systems, primarily through the development and use of state-of-the-art space-weather models. More information on MITHRAS can be found here.
