Dr. Alexandre Barreira (ORIGINS Fellow)

I am a theoretical and numerical cosmologist, and I work primarily on the area of large-scale structure, i.e., the distribution of the dark matter and galaxies on the largest observable scales of our Universe. Analyses of this large-scale structure can help answer many current open questions about the most fundamental constituents of our Universe, including the nature of dark energy and dark matter, the law of gravity on large-scales, the physics of inflation and the primordial Universe, and the mass of neutrino particles. During my PhD studies at Durham University in the UK, I focused on using large-scale structure observations to test theories of gravity beyond Einstein's theory of General Relativity. Over more recent years, as a postdoctoral researcher at the Max Planck Institute for Astrophysics in Munich, I have become increasingly interested in using combinations of numerical simulations and analytical theory techniques to make theoretical predictions for different aspects of our Universe. Now, as an ORIGINS fellow I am focused on extending these predictions further. I am interested in particular in studying the connection between the visible and the dark Universe (called galaxy bias), and optimizing the extraction of information about fundamental physics from observations of our Universe.
