Hayley Macpherson

Hayley Macpherson is a Postdoctoral Researcher at the University of Chicago, affiliated with the Enrico Fermi Institute and James Franck Institute. Her research focuses on cosmology, general relativity, and numerical relativity, with particular emphasis on understanding cosmological structure formation, inhomogeneous cosmology, and the effects of nonlinear gravity on the universe's evolution. She is also involved with the Einstein Toolkit, a computational framework for relativistic astrophysical simulations.

Her work bridges theoretical predictions and observational cosmology, addressing questions about the Hubble parameter's anisotropy, redshift drift in structured universes, and the impact of sky sampling on cosmological parameters. Her contributions include studies on void statistics, quadrupolar expansions in Hubble flow, and cosmographic methods for analyzing local universe properties.

Macpherson collaborates with institutions like Argonne National Laboratory and Fermilab, contributing to interdisciplinary projects in gravitational physics and astrophysics. Her research leverages advanced numerical methods and high-performance computing to model complex cosmological phenomena.
