Adrian E. Bayer is primarily a cosmologist who specializes in simulating and analyzing the large-scale structure of the universe and the cosmic microwave background. His work aims to optimally uncover the secrets of our universe, such as the fundamental nature of dark matter and dark energy and the mass of neutrinos. He also develops statistical and machine learning tools for use throughout astrophysics and beyond. Bayer studied physics at Imperial College London, earned a master’s in applied mathematics at the University of Cambridge, completed a Ph.D. in physics at the University of California, Berkeley, and now holds a joint research position at the Flatiron Institute and Princeton University.
