Research Interests

My research interests are in high-energy astrophysics and cosmology. I am particularly interested in finding non-gravitational evidence for dark matter. This has led me to investigate the astrophysics of the Galactic Center. It is there that the non-gravitational signatures of dark matter are likely to be largest but unfortunately, there are also a lot of astrophysical processes taking place in that location. These processes have to be accurately accounted for before one can determine if there is any residual dark matter self-annihilation signal.
