I’m interested in studying the evolution of galaxies and the dark matter haloes in which they reside. Many aspects of dark matter haloes are still not well understood. In particular through the use of N-body simulations I’ve studied what it means to have a “Milky Way-like” dark matter halo, how dark matter halo properties correlate with subhalo abundances, and what dark matter halo density profiles look like without their subhaloes. Because we reside within the Milky Way we have a much more limited understanding of its history and evolution. I have spent time with the SDSS-IV Milky Way as a galaxy group on determining photometric properties of the Milky Way using machine learning in order to better determine the Milky Way’s color and luminosity which provide insight into its evolution.
