My research has focused principally on how galaxies from and evolve and what their properties tell us about cosmology. I am particularly interested in small-scales, scales on which direct galaxy-galaxy interactions play an important role in the evolution of galaxies and their properties. My main tool is Sloan Digital Sky Survey. In my recent work my collaborators and I measured the two-point correlation function for the Luminous Red Galaxy sample in SDSS down to 10 kpc separations. Using this result we are trying to probe the profile of dark matter halos on these scales and put constrains on the inner cusp of the dark matter halo profiles.
Here you can find a JPEG of my poster on this topic for the Nearly Normal Galaxies in a ΛCDM Universe Conference.
