Research

I am a theoretical and computational cosmologist and am interested in cosmic evolution and structure formation. My research often utilizes numerical simulations run on supercomputers. I develop and apply N-body, hydrodynamic, and radiative transfer codes to simulate how structures form and evolve in the expanding Universe. I am interested in complex problems involving the gas, stars, galaxies, and galaxy clusters that we observe directly with modern telescopes. I am actively working on understanding how the first generation of stars, galaxies, and quasars reionized the Universe by the time it was a billion years old. As a member of the Atacama Cosmology Telescope (ACT) project, I work on discovering and interpreting massive galaxy clusters. As a member of the Sloan Digital Sky Survey (SDSS III) project, I work on using quasars as background sources to study the intervening intergalactic gas.
