Research Interests

My research focuses on what the formation and evolution of structure can tell us about the fundamental nature of our universe. My interests fall into a few broad categories:

  1. Large-Scale Structure (Clusters and Groups of Galaxies)
    1. Constraints on Cosmology ( DES, LSST)
    2. Non-thermal Emission and Particle Acceleration

  2. Indirect Detection of Dark Matter
    1. Multiwavelength (gamma-ray, X-ray, radio) Searches for DM Annihilation/Decay
    2. The Origin of X-ray Lines
    3. Constraints on DM Self-interaction

  3. Galaxy Evolution
    1. Hot Gas in Galaxies
    2. The Effects of Environment on Galaxies
    3. AGN populations as a function of environment

Most of my free time is spent with my family. I have two awesome, crazy boys, Alex and Nico. I also swim. I train with the Santa Cruz Masters, and I compete in open water races.
