Hello! My name is Derek Inman, and I am a scientist at iTHEMS whose research is focused on cosmology. Our Universe contains a substantial amount of dark matter the behavior of which we broadly know, but the composition of which we don’t. I try to understand how different ideas for what dark matter is (particles? black holes? something else?) change how the Universe looks and evolves at various times and length scales. I am particularly interested in cosmological structure formation, which rapidly becomes a nonlinear problem and so I tend to use numerical simulations run on supercomputers to understand the relevant physics.
