Alexandra Semposki is a postdoctoral scholar who received her Ph.D. in 2025 studying the application of Bayesian uncertainty quantification and model mixing to the dense matter equation of state (EOS), specifically neutron star matter. Her research covers a wide range of densities, and she is currently expanding her horizons to include finite temperature calculations, e.g., those of Fermi liquids, neutron star mergers, and hyperonic matter. Additionally, she is applying her model mixing techniques to nuclear reaction observables with collaborators at the Facility for Rare Isotope Beams (FRIB). Some of her other pursuits have included the development of emulators for computing the macroscopic properties of neutron stars. Alexandra is a member of the Bayesian Analysis of Nuclear Dynamics (BAND) and Modular Unified Solver of the Equation of State (MUSES) collaborations.
