I am a computational astrophysicist with research interests lying at the intersection of cosmology and galaxy evolution. Studying cosmology with measurements of large-scale structure pushes present-day theoretical tools to their limits. As large-scale surveys continue to produce richer measurements with higher precision, our discovery potential is increasingly limited by our ability to model cosmic structure formation with high accuracy. Much of my research focuses on developing new techniques to help present and near-future imaging surveys achieve their promise to uncover the physical nature of dark matter and dark energy. My work makes combined use of galaxy survey data, cosmological simulations, and data-driven semi-analytic modeling of the connection between galaxies and their dark matter halos.
