Eloisa Bentivegna is a senior research scientist at IBM. She has long worked on building computational models of strong-gravity systems, including binary black holes, black-hole lattices, and other nonlinear structures in cosmology. She has been a long-term contributor to the Einstein Toolkit and the author of package COSMOTOOLKIT, thanks to which she tackled the study of discrete gravitational structures in general relativity as a toy model for the formation and growth of structure in the universe. In 2012, she completed the first ever exact evolution of a black-hole lattice, a problem that had been open since 1957. In November 2015, she was part of one of the two collaborations that simulated the full relativistic evolution of a dust cosmological model. More recently, thanks to a £1.1m UKRI Future Leaders Fellowship, she has also been investigating new approaches to the search, optimisation, and problem inversion of large-scale models using physics-aware AI. Eloisa is an alumna of the Marie Curie and Rita Levi Montalcini fellowship schemes. She is an international committee member of the International Society on General Relativity and Gravitation, and a Fellow of the Royal Astronomical Society and of the Institute of Physics.
