Personal Bio I am passionate about cosmology (the development of the universe) as well as inspiring others' (especially young women's) interests in STEM. I’d love to offer advice on anything you have questions on. I explored how neutrinos with mass that scatter with other neutrinos in the early universe affect the cosmic microwave background (photons traveling towards us from 380,000 years after the big bang!) and structure growth (like galaxy formation); it is amazing how the smallest particles can have substantial effects on structure in the universe! During undergrad I also spent time on Mars research and wrote an optimization algorithm to extract the most mineralogical information possible from hyperspectral data taken by one of the Mars orbiters, information critical to planning the rover paths! After graduating I spent a year in Germany with a DAAD Scholarship doing research at the Max Planck Institute for Astrophysics on modified General Relativity and using current cosmological data sets to place bounds on the propagation of gravitational waves.
Fun Fact I’ve ridden horses my entire life and have competed at the World Championship a few times. I also enjoy singing and really want to try mounted archery.

Research Pitch This fall I am working with Bruce Draine on deriving from first principles the electron energy distribution in HII regions, which are mainly composed of ionized Hydrogen (e.g. Orion nebula). The goal is to establish what the distribution is and definitively rule out various models that have been proposed to explain temperature measurement discrepancies. My work is mainly numerical and involves relating fundamental physics to astrophysical phenomena. Chasing theories behind anomalous phenomena drives me: What physics can we learn if we analyze data differently? Some of the most fruitful questions arise when posed at the intersection of different fields and perspectives.
