Vivian Miranda is an Assistant Professor at the C.N. Yang Institute for Theoretical Physics at Stony Brook University. Her research lies at the intersection of theoretical cosmology and data science, with a focus on understanding dark energy, inflation, and the fundamental physics driving cosmic acceleration. Before joining Stony Brook in 2022, she was a Senior Research Associate and Postdoctoral Research Associate at the University of Arizona and a Postdoctoral Fellow at the University of Pennsylvania. She earned her Ph.D. in Astrophysics from the University of Chicago, where she worked with Professor Wayne Hu, and holds M.S. and B.S. degrees in Physics from the Federal University of Rio de Janeiro.

Research
Miranda’s research combines theoretical modeling, numerical simulations, and machine learning to probe the nature of dark energy and the evolution of the universe. Her work leverages data from major cosmological surveys—including the Dark Energy Survey, the Rubin Observatory Legacy Survey of Space and Time (LSST), and the Nancy Grace Roman Space Telescope—to test fundamental physics through multi-probe analyses of weak lensing, galaxy clustering, and supernova observations. She has developed novel statistical and AI-driven methods for cosmological inference, contributing to advances in how the field interprets tensions among key parameters such as the Hubble constant and matter density. Through her leadership in large collaborations and NASA science working groups, Miranda’s work is shaping the next generation of precision cosmology.
